Protection Functions60 DOCA0102EN-00 05/2016IntroductionSection 3.1IntroductionElectrical Distribution ProtectionPresentationMicrologic X control units are designed to provide protection against overcurrents and ground-fault currents.Micrologic X control units offer protection characteristics that comply with the requirements of standard IEC 60947-2.DescriptionWhen choosing protection characteristics, take into account:Overcurrents (overloads and short-circuits) and potential ground-fault currentsConductors that need protectionCoordination and selectivity between the devicesThe presence of harmonic currentsProtection characteristics can be represented on a trip curve that shows the circuit breaker trip time as a function of the measured current and protection settings. Protection settings are indexed on the rated current In of the Micrologic X control unit.Rated Current InThe protection setting ranges depend on the rated current In, defined by the sensor plug inserted in the Micrologic X control unit. The sensor plug can be replaced or modified. Mechanical mismatch protection prevents the installation of a sensor plug that is not compatible with the circuit breaker frame.For each circuit breaker frame size, the range of sensor plugs available is shown in the following table.Sensor plug MTZ1 frame rated current MTZ2 frame rated current MTZ3 frame rated currentIn 06 08 10 12 16 08 10 12 16 20 25 32 40 40 50 63400 A XXX––XX–––––––––630 A XXXX–XXX––––––––800 A – XXXXXXXX–––––––1000 A – – XXX–XXXX––––––1250 A – – – XX––XXXX–––––1600 A – – – – X–––XXXX––––2000 A – – – – – – – – – XXXXX––2500 A – – – – – – – – – – XXXXX–3200 A – – – – – – – – – – – XXXXX4000 A – – – – – – – – – – – – XXXX5000 A – – – – – – – – – – – – – – XX6300 A – – – – – – – – – – – – – – – X

Protection FunctionsDOCA0102EN-00 05/2016 65Long-Time Overcurrent Protection (L or ANSI Code 49RMS)PresentationLong-time overcurrent protection protects cables, busbars, and busbar trunking against overloads, based on the true RMS current. It is implemented independently for each phase and for the neutral.This protection function is an overcurrent time-dependent protection with thermal memory. It operates as a thermal image, using the heating and cooling model of a conductor. After tripping, the protection continues to integrate the cooling of the conductor.This protection function can be used also for transformer or generator protection thanks to the wide range of settings offered.AvailabilityLong-time overcurrent protection is available on:Micrologic 2.0 X, 5.0 X, 6.0 X, and 7.0 X control units3-pole and 4-pole circuit breakersLong-time overcurrent protection is powered by the current flowing through the internal current transformers of the circuit breaker and it does not require additional external power supply.Operating PrincipleThermal ImageThe control unit uses the calculation of a thermal image to evaluate the conductor heat rise and precisely monitor the thermal state of the conductors.Example:Comparison of the heat rise calculation without thermal image (diagram A) and with thermal image (diagram B):0 Instantaneous current (cyclical) in the load1 Conductor temperature2 Thermal state calculated without thermal image (diagram A), with thermal image (diagram B) 3 Long-time overcurrent protection thresholdControl unit without thermal image: On each current pulse, the control unit only considers the thermal effect on the pulse under consideration. No tripping occurs despite the build-up in conductor heat rise.Control unit with thermal image: The control unit adds the thermal effect of successive current pulses. Tripping occurs based on the actual thermal state of the conductor.The thermal image function protects cables and busbars from overheating in case of low-amplitude repetitive faults. Such faults can be due to repetitive motor starts, fluctuating load, intermittent ground faults, or subsequent closing after a fault.Long-time overcurrent protection is based on the true RMS current of phases and neutral, up to harmonic 15.Long-time overcurrent protection is implemented independently for each phase and for neutral when present (see page 76).132123AB00

Protection Functions66 DOCA0102EN-00 05/2016Traditional electronic protection does not protect against repetitive faults because the duration of each overload detected above the threshold setting is too short to trigger effective tripping. However, each overload involves a temperature rise in the installation. When cumulated, overloads can overheat the system.Thanks to its thermal memory, the thermal image function remembers and integrates thermal heating caused by each overload detected above the threshold setting:Before tripping, the integrated heating value reduces the associated time delay. The reaction of the control unit is closer to the real heating of the power network system.After tripping, the thermal function reduces the time delay when closing the circuit breaker on an overload.The thermal memory works whatever the current value. It offers an accurate image of the cable or busbar thermal status. The time constant is the same for heating and cooling.In the case of a control unit that is not supplied, the thermal memory is performed by a capacitor, which implies a fixed cooling time constant. The time constant is equivalent to a tr setting of 12 seconds.Thermal Memory ResetThe thermal memory can be reset with Ecoreach software.The thermal memory reset is recorded as an event.Setting the ProtectionThe long-time overcurrent protection settings are:Ir long-time overcurrent protection thresholdtr long-time overcurrent protection time delayThey can be set as follows:On the Micrologic X display screen, at Home → Protection → I Long timeWith Ecoreach softwareWith Masterpact MTZ mobile AppBy sending a setting command using the communication network.Long-time overcurrent protection can be duplicated when dual settings are activated (see page 78).Protection SettingsThe tr long-time overcurrent protection time delay is given in cold-state conditions, and for a phase or neutral current equal to 6 x Ir. When the current is higher than Isd or Ii, only short-time overcurrent protection and instantaneous protection are operational.Tripping Time According to tr Time DelayProtection CharacteristicsThe accuracy on the tr time delay is:-20% to 0% when tr > 2 s-25% to 0% when tr = 2 s-30% to 0% when tr < 2 sIr characteristics:I < 1.05 x Ir: no tripI > 1.2 x Ir: tripSetting Unit Range Step Factory settingIr threshold A 0.4–1 x In 1 A 1 x Intr time delay s 0.5–24 0.5 0.5tr setting (tripping time at 6 x Ir) 0.5 s 1s 2s 4s 8s 12 s 16 s 20 s 24 sResulting tripping time at 1.5 x Ir 12.5 s 25 s 50 s 100 s 200 s 300 s 400 s 500 s 600 sResulting tripping time at 7.2 x Ir 0.34 s 0.69 s 1.38 s 2.7 s 5.5 s 8.3 s 11 s 13.8 s 16.6 s

It includes two characteristics, definite time and inverse time, which depend on the status of the I²t setting.AvailabilityShort-time overcurrent protection is available on:Micrologic 5.0 X, 6.0 X, and 7.0 X control units3-pole and 4-pole circuit breakersShort-time overcurrent protection is powered by the current flowing through the internal current transformers of the circuit breaker and it does not require an additional external power supply.Operating PrincipleShort-time overcurrent protection is based on the true RMS current of phases and neutral, up to harmonic 15.In order to trip on an intermittent fault, the control unit accumulates the intermittent currents in the short-time tripping range that do not last long enough to trigger a trip. This accumulation may lead to shorter tripping times than those set. Setting the ProtectionThe short-time overcurrent protection settings are:Isd short-time overcurrent protection thresholdtsd short-time overcurrent protection time delayI²t short-time overcurrent protection curve (I²t ON or I²t OFF)They can be set as follows:On the Micrologic X display screen, at Home → Protection → I Short timeWith Ecoreach softwareWith Masterpact MTZ mobile AppBy sending a setting command using the communication network.

The protection operates with a definite time characteristic. It trips without additional time delay as soon as the setting current is exceeded. The protection offers two typical total breaking times:Standard breaking time of 50 ms, used for applications requiring selectivity. Full selectivity can be ensured with any Compact NSX circuit breaker installed downstream of a Masterpact device (for Ue ≤ 440V and MTZ other than type L. Refer to selectivity tables for details).Fast breaking time of 30 ms, typically used for applications where the thermal constraints of the equipment need to be limited and when selectivity is not required.NOTE: On Micrologic 2.0 X, instantaneous protection is a short-time protection without time setting.AvailabilityInstantaneous overcurrent protection is available on:Micrologic 2.0 X, 5.0 X, 6.0 X, and 7.0 X control units3-pole and 4-pole circuit breakersIt is powered by the current flowing through the internal current transformers of the circuit breaker and it does not require an additional external power supply.Operating PrincipleThe instantaneous overcurrent protection threshold sets the level of short-circuit current at which the circuit breaker trips with no intentional time delay.For Micrologic 5.0 X, 6.0 X, 7.0 X control units, instantaneous overcurrent protection can be disabled.Instantaneous overcurrent protection overrides short-time overcurrent protection when the instantaneous overcurrent threshold is adjusted to the same or a lower setting than the short-time overcurrent threshold.Setting the Protection for Micrologic 2.0 XProtection Settings for Micrologic 2.0 XProtection Characteristics for Micrologic 2.0 XThe instantaneous overcurrent protection setting for Micrologic 2.0 X is:Isd short-time overcurrent protection threshold (without time setting)It can be set as follows:On the Micrologic X display screen, at Home → Protection → I InstantaneousWith Ecoreach softwareWith Masterpact MTZ mobile AppBy sending a setting command using the communication network.

Protection Functions72 DOCA0102EN-00 05/2016Ground-Fault Protection (G or ANSI Code 50G/51G)PresentationGround-fault protection ensures protection against phase-to-ground fault, which is more sensitive than protection based on phase current only. It is generally used in TN-S systems but could also be used in other earthing systems. Ground-fault protection is based either on the summation of the phases and neutral current or on the signal delivered by an external sensor, source ground return (SGR) current transformer through the MDGF module. NOTE: Ground-fault protection is also called earth-fault protection.AvailabilityGround-fault protection is available on:Micrologic 6.0 X control units3-pole and 4-pole circuit breakersExternal sensors can be used:Source ground return protection: including ground-fault protection and an SGR sensor installed around the connection of the transformer neutral point to ground.External Neutral Current Transformer (ENCT): measurement of the current on neutralGround-fault protection is powered by the current flowing through the internal current transformers of the circuit breaker and it does not require an additional external power supply.Operating PrincipleThe ground-fault current is calculated or measured according to the circuit breaker configuration, as shown in the following table.Ground-fault protection is based on the true RMS current of phases and neutral, up to harmonic 15.In order to trip on an intermittent fault, the control unit accumulates the intermittent currents in the ground-fault tripping range that do not last long enough to trigger a trip. This accumulation leads to shorter tripping times than those set.Setting the ProtectionGround-fault protection can be enabled or disabled.The ground-fault protection settings are:Ig enableIg ground-fault protection thresholdtg ground-fault protection time delayGround-fault protection curve (I²t ON or I²t OFF)They can be set as follows:On the Micrologic X display screen, at Home → Protection → I Ground FaultWith Ecoreach softwareCircuit breaker configuration Ig ground-fault current3P Ig = I1 + I2 + I34P Ig = I1 + I2 + I3 + IN3P + ENCT Ig = I1 + I2 + I3 + IN (ENCT)3P or 4P + SGR Ig = ISGRThe ground-fault protection threshold Ig sets the level of ground-fault current at which the circuit breaker trips when reaching the ground-fault protection time delay tg.The time delay tg sets the length of time during which the circuit breaker carries a ground-fault within the ground-fault protection threshold Ig range.The time delay tg can be adjusted to:Four setting values with I²t ON. In this case, the tripping curve is an inverse time curve up to 2 x Ir, meaning that the time delay decreases as the current increases. Above 2 x Ir, the tripping curve is a definite time curve with a constant tripping time.Five setting values with I²t OFF. In this case, the tripping curve is a definite time curve with a constant tripping time.

A typical application is to adjust short-circuit protection when the circuit breaker can be supplied by two sources with very different short-circuit currents. For example, the circuit breaker is supplied by either the grid or a generator.AvailabilityThe dual settings function is available on Micrologic 2.0 X, 5.0 X, 6.0 X, 7.0 X.Operating PrincipleWhen the dual settings function is enabled, two sets of protection parameters are available:Set A corresponds to the settings currently selectedSet B is a new set of protection parameters, which can be set as described in Setting the Function (see page 78).Set B is activated as follows:On the Micrologic X display screen at Home → Maintenance → Switch to other set → Switch to set B.By sending a setting command using the communication network.

Protection Functions80 DOCA0102EN-00 05/2016Zone Selective Interlocking (ZSI)PresentationZone-selective interlocking (ZSI), also called zone restraint, is a system designed to reduce the stress on electrical distribution equipment during short-circuit or ground-fault conditions.ZSI works with a previously coordinated distribution system to limit fault stress on the system by reducing the time it takes to clear the fault while maintaining system coordination between overcurrent and ground-fault protective devices.ZSI allows Micrologic X control units to communicate with each other so that a short-circuit or ground-fault can be isolated and cleared by the nearest upstream circuit breaker with no intentional time delay. Devices in all other areas of the system (including upstream) remain closed to maintain service to unaffected loads.Without ZSI, a coordinated system results in the circuit breaker closest to the fault clearing the fault, but usually with an intentional delay. With ZSI, the device closest to the fault ignores its preset short-time and ground-fault delays and clears the fault with no intentional delay.Zone-selective interlocking eliminates intentional delay without sacrificing coordination and it results in faster tripping times. This limits fault stress by reducing the amount of let-through energy the system is subjected to during an overcurrent.The use of ZSI does not cause circuit breakers that are not coordinated (due to improper settings) to coordinate.AvailabilityZone-selective interlocking is available on Micrologic 5.0 X, 6.0 X, and 7.0 X control units.For more information on compatibility and hard wiring, refer to the ZSI Instruction Sheet.Masterpact circuit breakers with ZSI capability are shipped with self-restraint jumpers installed. Self-restraint jumpers must be in place unless zone selective interlocking is activated. If jumpers are removed and zone selective interlocking is not activated, the circuit breaker ignores its programmed delay and trips with no intentional delay.Operating PrincipleA pilot wire interconnects a number of circuit breakers equipped with Micrologic X control units, as illustrated in the following diagram.The control unit detecting a fault sends a signal upstream and checks for a signal arriving from downstream. If there is a signal from downstream, the circuit breaker remains closed for the full duration of its tripping delay. If there is no signal from downstream, the circuit breaker opens immediately, regardless of the tripping-delay setting.Fault 1: Only circuit breaker A detects the fault. Because it receives no signal from downstream, it opens immediately, regardless of its tripping delay set to 0.3.Fault 2: Circuit breakers A and B detect the fault. Circuit breaker A receives a signal from circuit breaker B and remains closed for the full duration of its tripping delay, set to 0.3. Circuit breaker B does not receive a signal from downstream and opens immediately, in spite of its tripping delay set to 0.2.

Protection FunctionsDOCA0102EN-00 05/2016 81NOTE: On device A, the tsd and tg tripping delays must not be set to zero because this would make selectivity impossible.Setting the FunctionThe following settings can be assigned to the ZSI input:Ground-fault protection (Micrologic 6.0 X) Short-time overcurrent protectionBoth protections (factory setting)Setting changes can be made as follows:With Ecoreach softwareBy sending a setting command using the communication network.

Protection FunctionsDOCA0102EN-00 05/2016 87Setting the Long-Time Overcurrent Protection (L or ANSI Code 49RMS)Setting Guidelines for Ir The Ir setting depends on the maximum expected current flow through the breaker and the maximum current that can be withstood by the protected equipment (for example, cables, busbars, generators, and transformers).The installation rules, such as IEC 60364 Chapter 4.43 or similar national standards, require overload protection for conductors as follows:Ib Maximal load currentIr Long time protection settingIz Continuous current-carrying capacity of the circuitI2 Conventional operating current of the circuit breaker = 1.2 x Ir for Schneider Electronic control unitI(A) Current through circuit breaker (phase(s) or neutral)Setting Guidelines for trThe tr setting depends on the maximum duration at maximum current and the maximum current that can be withstood by the protected equipment (for example, cables, busbars, generators, and transformers).Thermal memory: As described in long-time overcurrent protection (see page 65), this protection function is an overcurrent time-dependent protection with thermal memory. It operates as a thermal image, using the heating and cooling model of a conductor. It can be considered as a first order thermal model with one heating time constant.The following table shows the relationship between the tr setting and the thermal time constant of the first thermal model:Summary of tr Setting Guidelines by ApplicationThe following table gives the tr setting guidelines by application:lb lr lz l (A)1,45x lzl2= 1,2 lr <= 1,45 lztr setting (s) Unit 0.5 124812 16 20 24Equivalent time constant for heating and cooling when control unit is energizedseconds 14 28 56 112 224 335 447 559 671minutes – – – – 3.5 5.6 7.5 9.3 11.2Time constant for cooling when control unit is not energizedminutes 5Application Principle Usual valueSecondary side of MV/LV transformer (switchboard main incomer) Tie circuit breaker between two switchboardsTripping time according to circuit thermal withstand for busbars, busbar trunking, cable > 240 mm2:Time constant > 11 mintr = 24 sWhen smaller cables are used in parallel, a lower setting should be used.tr ≤ 24 s

The peak value of the first current wave often reaches 10 to 15 times the rated rms current of the transformer and may reach values of 20 to 25 times the rated current even for transformers rated less than 50 kVA.Example of inrush current: when transformer is switched on:A 1st peak 10 to 25 x InExample of inrush current of direct on line motor when started:Application Principle Isd usual valueSecondary side of MV/LV transformer (switchboard main incomer or tie circuit breaker between two switchboards)Lower than minimum short-circuit or ground-fault current at the end of the protected circuit.Selectivity with downstream circuit breakers10 x IrGenerators Lower than minimum short-circuit or ground-fault current supplied by the generator.Selectivity with downstream circuit breakers2–3 x IrFeeder with other Masterpact or Compact NS 630–3200 A downstreamLower than minimum short-circuit or ground-fault current at the end of the protected circuit.Selectivity with downstream circuit breakers10 x IrFeeder without other Masterpact or Compact NS 630–3200 A downstreamLower than minimum short-circuit or ground-fault current at the end of the protected circuit.Selectivity with downstream circuit breakers10 x IrPrimary side of LV/LV transformer Lower than minimum secondary short-circuit current.10 x IrPower electronic (for example, uninterruptible power supplies, variable speed drives, photovoltaic inverters)Lower than minimum short-circuit or ground-fault current at the end of the protected circuit.Lower setting possible as no selectivity or transient current is expected.1.5–2 x IrMotors Lower than minimum short-circuit or ground-fault current at the end of the protected circuit.Lower setting possible above starting current.10 x IrAIInTItId (5 – 8 In)In10 – 20 ms td (1 – 10 s)

This function allows the curve to be smoothed for low level overcurrent, ensuring fast trip at high current. This is recommended for selectivity with fuses.Application Principle tsd usual valueSecondary side of MV/LV transformer (switchboard main incomer or tie circuit breaker between two switchboards)Selectivity with downstream circuit breakerstsd > tsd of downstream power circuit breaker (tsd = 0.2 s if installation includes three levels of power circuit breaker)Feeder with selectivity with other Masterpact MTZ or Compact > 630 A downstreamSelectivity with downstream circuit breakerstsd > tsd of downstream power circuit breaker (tsd = 0.1 s if installation includes three levels of power circuit breaker)Feeder without selectivity with other Masterpact MTZ or Compact > 630 A downstreamNo need for delayed short-time protectiontsd=0sPrimary side of LV/LV transformer Stability during inrush.Selectivity with downstream circuit breakerstsd = 0.1 s ortsd > tsd of downstream power circuit breaker, if anyPower electronic (Uninterrupted power supplies, variable speed drives, photovoltaic inverters, etc.)No need for delayed short-time protectiontsd=0sMotors Stability during inrush tsd = 0 s or 0.1 s

Protection FunctionsDOCA0102EN-00 05/2016 93SelectivityCoordination Between DevicesCoordination between the upstream and downstream devices, especially selectivity, is essential to optimize continuity of service. The large number of options for setting the protection functions on Micrologic X control units improves the natural coordination between circuit breakers.Three selectivity techniques can be used:Current selectivity, which corresponds to staging of the long-time overcurrent protection threshold.Time selectivity, which corresponds to staging of the short-time overcurrent protection threshold.Energy selectivity, which corresponds to staging of the circuit breaker energy levels: this applies for high intensity short-circuit currents.Selectivity RulesThe selectivity rules depend on:The type of control unit on the circuit breakers installed upstream and downstream: electronic or thermal-magnetic.The accuracy of the settings.Selectivity of Overcurrent ProtectionFor overcurrent protection, the selectivity rules between electronic control units are as follows: Current and time selectivity:A ratio of Ir Q1/Ir Q2 greater than or equal to 1.3 is sufficient between the Ir threshold for long-time protection of the control unit on the upstream circuit breaker Q1 and that of the control unit on the downstream circuit breaker Q2.The tr time delay for long-time protection of the control unit on the upstream circuit breaker Q1 is identical or greater than that of the control unit on the downstream circuit breaker Q2.A ratio of 1.5 is sufficient between the Isd threshold for short-time protection of the control unit on the upstream circuit breaker Q1 and that of the control unit on the downstream circuit breaker Q2.The tsd time delay for short-time protection of the control unit on the upstream circuit breaker Q1 is greater than that of the control unit on the downstream circuit breaker Q2.If the upstream circuit breaker is in the I2t off position, the downstream circuit breakers must not be in the I2t on position.Energy selectivity is provided by the circuit breaker design and build characteristics. The selectivity limit can only be guaranteed by the manufacturer.Ground-Fault Protection SelectivityFor ground-fault protection, only the rules for time selectivity should be applied to the Ig protection threshold and tg time delay: A ratio of 1.3 is sufficient between the Ig threshold for ground-fault protection of the control unit on the upstream circuit breaker Q1 and that of the control unit on the downstream circuit breaker Q2.The tg time delay for ground-fault protection of the control unit on the upstream circuit breaker Q1 is greater than that of the control unit on the downstream circuit breaker Q2.If the upstream circuit breaker is in theI2t off position, the downstream circuit breakers must not be in theI2t on position.

Protection Functions94 DOCA0102EN-00 05/2016Selectivity LimitDepending on the staging of circuit breaker ratings and protection parameter settings, selectivity can be:Limited (partial selectivity) up to a value lower than the maximum expected short-circuit current.Total (total selectivity), performed irrespective of the value of the short-circuit current.Selectivity TableSchneider Electric provides selectivity tables showing the type of selectivity (partial or total) between each circuit breaker for its entire range of circuit breakers (refer to the Complementary Technical Information Catalog).I2t ON/OFF FunctionUse the I2t inverse time curve function to improve circuit breaker coordination. Use it when a protection device using inverse time only is installed upstream or downstream, for example a fuse protection device.I2t OFF I2t ONt(s)gG - 250 ANS800N - Micrologic 5.0 A - 800 A I (A) t(s)gG - 250 ANS800N - Micrologic 5.0 A - 800 A I (A)

All parameters are not displayed on all interfaces (see page 107).An optional external 24 Vdc supply or VPS module is mandatory to measure and display parameters, including energy counters, for currents below 20% of the rated current.Measurement AccuracyPower and energy metering accuracy in Masterpact MTZ with Micrologic X control unit is classified as Class 1, according to IEC 61557-12. This standard specifies performance requirements of measuring and monitoring devices that measure and monitor the electrical parameters within electrical distribution systems. It covers both performance measuring devices with external sensors (PMD-S), such as current and/or voltage transformers, for example, stand-alone power meters, and performance measuring devices with embedded sensors (PMD-D), for example, circuit breakers.Masterpact MTZ, with Micrologic X control unit and embedded sensors, is a PMD-DD device with Class 1 accuracy, according to IEC 61557-12 for power and energy metering. It complies with the requirements of K70 temperature class, according to table 6 of IEC 61557-12.The IEC 61557-12 standard defines the following three levels of uncertainty that need to be checked to establish accuracy class:Intrinsic uncertainty (see page 98)Operating uncertainty (see page 99)Overall system uncertainty (see page 100)A PMD-DD device avoids overall system uncertainty and variation, thanks to its embedded sensors and wiring.Measured Electrical Parameter UncertaintyUncertainty is the estimated percentage by which a measured electrical parameter may differ from the true electrical parameter. In the context of this standard, the total uncertainty of a measured electrical parameter depends on the instrument, the environment, and other elements to be considered.The graphic below shows the total uncertainty of a measured electrical parameter made by:  A PMD-D device, with embedded sensors A PMD-S device, with external sensors
