LSIG Protection

Long-Time Protection

Long-time protection protects equipment

against overloads.• Long-time protection is standard on all trip

units.

• Long-time pickup (Ir) (A) sets themaximum current level based on sensorplug rating (In) which the circuit breakerwill carry continuously. If current exceedsthis value, circuit breaker will trip after thepreset time delay. The long-time pickup(Ir) is adjustable from 0.4–1.0 times thecircuit breaker sensor plug rating (In) (D).

• Long-time delay (tr) (B) sets the length oftime that the circuit breaker will carry an

overcurrent below the short-time orinstantaneous pickup current level beforetripping. Two options are available:

— Standard I2t long-time delay curve.See Table 1 for I2t long-time delaysettings.

— Idmtl (inverse definite minimum timelag) long-time delay curves vary inslope to enhance selectivity.

NOTE: Micrologic trip units are powered from the circuit to alwaysprovide fault protection. All other functions (display, metering,communications, etc.) require external power. See page 15 for more

information.Figure 4: Long-Time Protection Switches

• The overload indicator light (C) indicatesthat the long-time pickup threshold Ir hasbeen exceeded.

• For Masterpact™ NT and NW circuitbreakers, sensor value (In) can bechanged by replacing sensor plug (D)located below the trip unit. For furtherinformation, see the instructions packed

with the sensor plug replacement kit.• Neutral protection is not available when

Idmtl protection is selected.

• The Idmtl selections do not utilize thesame thermal imaging feature as the I2tlong-time protection function. Both thebasic long-time protection and Idmtl EITare I2t curves, but the different thermalimaging features result in different system

performances. For welding applications itis recommended the basic I2t long-timeprotection be used to ensure expectedsystem performance.

• Both long-time pickup and long-time delayare located on the field-replaceableadjustable rating plug. To change settingsto more precisely match the application,various rating plugs are available. Forinstructions on replacing the rating plug,see Section 6—Adjustable Rating PlugReplacement.

• Long-time protection uses true RMS

measurement.Thermal imaging provides continuoustemperature rise status of the wiring, bothbefore and after the device trips. This allowsthe circuit breaker to respond to a series ofoverload conditions which could causeconductor overheating, but would goundetected if the long-time circuit wascleared every time the load dropped belowthe pickup setting or after every trippingevent.

NOTE: If checking trip times, wait a minimumof 15 minutes after circuit breaker trips before

resetting to allow the thermal imaging to resetcompletely to zero or use a test kit to inhibitthe thermal imaging.

Short-Time Protection

Short-time protection protects equipmentagainst short circuits.

• Short-time protection is standard on 5.0P

and 6.0P trip units.• The short-time pickup (Isd) (A) sets currentlevel (below instantaneous trip level) atwhich circuit breaker will trip after the presettime delay.

• The short-time delay (tsd) (B) sets the lengthof time that the circuit breaker will carry anovercurrent above the short-time pickupcurrent level before tripping.

• The I2t on/I2t off option provides improvedselectivity with downstream protectivedevices:

— With I2t off selected, fixed time delay is

provided.— With I2t on selected, inverse time I2t

protection is provided up to 10 x Ir. Above 10 x Ir, fixed time delay isprovided.

• Intermittent currents in the short-time trippingrange which do not last sufficiently long totrigger a trip are accumulated and shortenthe trip delay appropriately.

• Short-time protection can be zone-selectiveinterlocked (ZSI) with upstream ordownstream circuit breakers. Setting tsd tothe 0 setting turns off zone-selective

interlocking.• Short-time protection uses true RMS

measurement.

• Short-time pickup and delay can be adjustedto provide selectivity with upstream ordownstream circuit breakers.

NOTE: Use I2t off with ZSI for propercoordination. Using I2t on with ZSI is notrecommended as the delay in the upstreamdevice receiving a restraint signal could result inthe trip unit tripping in a time shorter than thepublished trip curve.

Instantaneous Protection

Instantaneous protection protects equipmentagainst short circuits with no intentional timedelay.

• Instantaneous protection (Ii) (A) is standardon all trip units.• Instantaneous protection is based on the

circuit breaker sensor rating (In).

• Circuit breaker open command is issued assoon as threshold current is exceeded.

• Instantaneous protection uses peak currentmeasurement.

• When instantaneous protection switch is setto off, the instantaneous protection isdisabled.

Ground-Fault Protection for Equipment

Equipment ground-fault protection protectsconductors against overheating and faults fromground-fault currents ( 1200 A).

• Equipment ground-fault protection isstandard on 6.0P trip units.

• Ground-fault pickup (Ig) (A) sets groundcurrent level where circuit breaker will tripafter the preset time delay.

• Ground-fault delay (tg) (B) sets the length oftime that the circuit breaker will carry aground-fault current above the ground-faultpickup current level before tripping.

• Equipment ground-fault protection can bezone-selective interlocked (ZSI) withupstream or downstream circuit breakers.Setting the ground-fault delay (tg) to the 0setting turns off zone-selective interlocking.

• Neutral protection and equipment ground-fault protection are independent and canoperate concurrently.

NOTE: Use I2t off with ZSI for propercoordination. Using I2t on with ZSI is notrecommended as the delay in the upstreamdevice receiving a restraint signal could result inthe trip unit tripping in a time shorter than thepublished trip curve.

Micrologic 6.0P Trip Unit


16/300

E NGL I S H



Micrologic Trip Unit Configuration

Control Power The P trip unit is designed to be used with an external 24 Vdc power supply.The large LCD display used by the P trip unit requires too much current tobe powered by current flow through the circuit breaker.

The P trip unit has a circuit voltage power supply which will power the tripunit when there is approximately 150 Vac or more between two phases. Thestandard configuration for the voltage probes inside the circuit breaker is atthe bottom connections. If the circuit breaker is open in a top fed application,there is no voltage at the bottom of the circuit breaker and the trip unit willnot be powered.

The following will be powered and functional even if the trip unit is notexternally powered:

• Fault protection for LSIG functions. The P trip unit is fully circuit poweredfor fault protection.

• LED trip indication (powered by an onboard battery). The battery’s onlyfunction is to provide LED indication if all other power is off.

• Ground-fault push-to-trip button works for testing ground fault when thetrip unit is powered by the circuit voltage power supply. The ground-faultpush-to-trip is also functional if a Hand-Held Test Kit or Full-FunctionTest Kit is powering the trip unit.

The following will be powered and functional with external power:

• All of the above functions which are functional without external power.• LCD display and backlight are functional. Backlight intensity is not

controlled or adjustable, and may be different from one trip unit toanother.

• All metering, monitoring, and history logs are functional.• Communications from the trip unit to M2C and M6C programmable

contact modules are powered by a 24 Vdc power supply at F1 and F2.The M6C also required an external 24 Vdc power supply.

• Modbus communications are functional, using a separate 24 Vdc powersupply for the circuit breaker communications module. This separate 24Vdc power supply is required to maintain the isolation between the tripunit and communications.

• The ground-fault push-to-trip is also functional if a Hand-Held Test Kit orFull-Function Test Kit is powering the trip unit.


17/300



External Power SupplyThe trip unit can be powered by:

• 24 Vdc external power supply (recommended).• Over 150 V on the bottom circuit breaker terminals on two phases.• Over 150 V on the top circuit breaker terminals with external voltage

option.

Power supply is used for:

Graphic screen display when the circuit breaker is open and top fed.

Option of linking an alarm to a relay output.

To maintain date and time when the circuit breaker is open.

Advanced Protection

Neutral Protection

Neutral protection protects neutral conductorsagainst overheating.

• For a three-pole circuit breaker, neutralprotection is possible if a neutral currenttransformer is used.

— Adjust the neutral using the trip unitkeypad.

— Possible settings are OFF, N/2, N, or1.6N.

— Factory setting is OFF.

— Oversize neutral protection (1.6N)requires use of the appropriate oversizeneutral current transformer.

NOTICE

HAZARD OF EQUIPMENT DAMAGEIf a four-pole circuit breaker neutral pole switch is set to 4P3D setting, thecurrent in the neutral must not exceed the rated current of the circuitbreaker.

For a three-pole circuit breaker with oversize neutral protection (1.6N),select the appropriate oversize neutral current transformer.

Failure to follow this instruction can result in equipment damage.

• For a four-pole circuit breaker, set systemtype using the circuit breaker neutral selectordial (see Figure 9).

— Make fine adjustments using the trip unitkeypad, with the circuit breaker dialsetting providing the upper limit foradjustment.

— Factory setting is 4P4D.

Alarms

Alarms can be enabled or disabled for protectionor load shedding.

• When an alarm occurs, an entry is made in

the alarm log.• For a trip unit to activate an alarm, both thepickup level and time delay must beexceeded. Therefore for LSIG protection andadvanced protection programmed to trip thecircuit breaker, the trip unit will not activatethe alarm until the circuit breaker trips. (Forexample, if a relay is programmed for thelong-time pickup Ir, the trip unit will not signalan alarm when the long-time overloadindicator lights. The trip unit will only activatethe alarm once the long-time overloadexceeds the time delay and trips the circuitbreaker.)

• Link alarms to a visual or audible signal byprogramming the optional M2C or M6Cmodule contacts, when an external 24 Vpower supply is used on the trip unit.

• View alarms by:

— History logs menu

— The network system managementsoftware

• M2C/M6C contact characteristics:

— Minimum load of 100 mA/24 V

— Breaking capacity at a 0.7 power factor

Reverse Power Protection (rPmax)

Reverse power protection protects alternatorsagainst absorption of the total actual power overall three phases in the event that a drive motorfails.

• Reverse power protection applies a tripcurve based on the total actual power value(A) over all three phases.

• A time delay (B) starts timing if the totalactual power of the three phases is notflowing in the defined direction and if itexceeds a reverse power threshold.

• The power direction is defined during trip unitsetup.

Phase Rotation Protection Protects the circuit when two of the three phases are reversed.

• If one of the phases is down, this protection is inactive.• Options are ABC or ACB.• When system frequency is set to 400 Hz, phase rotation protection is

disabled.

• Do not use phase rotation protection to determine the loss of multiplephases in delta connected systems.

Load Shedding

Load shedding does not trip the circuit breaker,but may be used to activate an alarm linked toan M2C or M6C contact (controlling non-prioritynetwork loads).

• Load shedding is defined by a threshold andtime delay:

A—Activation threshold

B—Activation time delay

C—Dropout threshold

D—Dropout time delay

• Power load shedding depends on the flowdirection set during trip unit setup.

• Current load shedding is connected to the I2tor Idmtl long-time delay values.

• Current load shedding cannot be activated if“Long-time OFF” rating plug is installed.

Metering The Micrologic P trip unit provides continuous metering of system values.Metered values can be checked using the graphic display screen or networksystem management software.

Trip Unit Testing Trip unit LSIG functions can be tested using primary injection testing orsecondary injection testing. Test trip unit using the full-function test kit orhand-held test kit. (See “Trip Unit Installation Check” on page 66 for moreinformation.)

Operation Counter The circuit breaker communication module is required to display the totalnumber of times the circuit breaker has opened since initial installation andsince the last reset and the day/time of last reset

Zone-selective Interlocking

Short-time and ground-fault protection can beinterlocked to provide zone-selectiveinterlocking.

Control wiring links several trip units in thedistribution network and in the event of a fault, atrip unit will obey the set delay time only ifreceiving a signal from a downstream trip unit.

If the trip unit does not receive a signal, trippingwill be instantaneous (with no intentional delay).

• The fault is cleared instantaneously by thenearest upstream circuit breaker.

• Thermal stresses (I2t) in the network areminimized without any effect on the correcttime delay coordination of the installation.

NOTE: Use I2t off with ZSI for proper coordination. Using I2t on with ZSI isnot recommended as the delay in the upstream device receiving a restraintsignal could result in the trip unit tripping in a time shorter than the publishedtrip curve.

NOTE: Setting short-time delay (tsd) or ground-fault delay (tg) to the 0

setting will eliminate selectivity for that circuit breaker.

Figure 16 shows circuit breakers 1 and 2 zone-

selective interlocked.• A fault at A is seen by circuit breakers 1 and

2. Circuit breaker 2 trips instantaneously andalso informs circuit breaker 1 to obey setdelay times. Thus, circuit breaker 2 trips andclears the fault. Circuit breaker 1 does nottrip.

• A fault at B is seen by circuit breaker 1.Circuit breaker 1 trips instantaneously sinceit did not receive a signal from thedownstream circuit breaker 2. Circuit breaker1 trips and clears the fault. Circuit breaker 2does not trip.

buttons: A. Bar Graph Display—Provides real-time bar

graph display of line currents andmeasurement of line current and neutralcurrent (if applicable) (default display)

B. Metering Menu—Provides access tometered values of current, voltage, power,energy and frequency

C. Maintenance Menu—Allows user to changethe trip unit configuration and providesaccess to history logs

D. Protection Menu—Allows precisionadjustments to basic and advanced

protectionWhen the switch cover is closed, the trip unit willreturn to the bar graph (default) display after 3.5minutes of no input. (If the switch cover is open,the display stays at the window selected.) Toaccess another menu, press the button thatcorresponds to the desired menu. The menuappears on the display and the green LEDbelow the menu button lights up.
