Functionsand characteristics
Protection settings........................................................
Protection thresholds and delays are set using the adjustment dials.
The selected values are momentarily displayed in amperes and in seconds.
Overload protectionTrue rms long-time protection.
Thermal memory: thermal image before and after tripping.Setting accuracy may be enhanced by limiting the setting range using a different
long-time rating plug.
The long-time rating plug "OFF" enables to cancel the overload protection.
Short-circuit protectionShort-time (rms) and instantaneous protection.
Selection of I2t type (ON or OFF) for short-time delay.
Earth fault protectionResidual or source ground return.Selection of I2t type (ON or OFF) for delay.
Residual earth-leakage protection (Vigi).Operation without an external power supply.
Protected against nuisance tripping.k DC-component withstand class A up to 10 A.
Neutral protectionOn three-pole circuit breakers, neutral protection is not possible.
On four-pole circuit breakers, neutral protection may be set using a three-position
switch: neutral unprotected (4P 3d), neutral protection at 0.5 In (4P 3d + N/2),neutral protection at In (4P 4d).
Zone selective interlocking (ZSI)A ZSI terminal block may be used to interconnect a number of control units toprovide total discrimination for short-time and earth-fault protection, without a delay
before tripping.
"Ammeter" measurements ...........................................menu
Micrologic A control units measure the true rms value of currents.
A digital LCD screen continuously displays the most heavily loaded phase (Imax)
or displays the I1, I2, I3, IN, Ig, In, stored-current (maximeter) and setting values bysuccessively pressing the navigation button.
The optional external power supply makes it possible to display currents < 20% In.
Communication option
In conjunction with the COM communication option, the control unit transmits thefollowing:

Control unitsMicrologic P "power"
Functionsand characteristics
Micrologic P control units include all thefunctions offered by Micrologic A.
In addition, they measure voltages andcalculate power and energy values.They also offer new protection functionsbased on currents, voltages, frequency andpower reinforce load protection.
Protection settings........................................................ +
The adjustable protection functions are identical to those of Micrologic A
(overloads, short-circuits, earth-fault and earth-leakage protection).
Double settingWithin the range determined by the adjustment dial, fine adjustment of thresholds
(to within one ampere) and time delays (to within one second) is possible on thekeypad or remotely using the COM option.
IDMTL settingCoordination with fuse-type or medium-voltage protection systems is optimised byadjusting the slope of the overload-protection curve. This setting also ensures
better operation of this protection function with certain loads.
Neutral protectionOn three-pole circuit breakers, neutral protection may be set using the keypad or
remotely using the COM option, to one of four positions: neutral unprotected (4P3d), neutral protection at 0.5 In (4P 3d + N/2), neutral protection at In (4P 4d) and
neutral protection at 1,6 In (4P 3d + 1,6N). Neutral protection at 1,6 In is used whenthe neutral conductor is twice the size of the phase conductors (major load
imbalance, high level of third order harmonics).On four-pole circuit breakers, neutral protection may be set using a three-position
switch or the keypad: neutral unprotected (4P 3d), neutral protection at 0.5 In (4P
3d + N/2), neutral protection at In (4P 4d). Neutral protection produces no effect ifthe long-time curve is set to one of the IDMTL protection settings.
Programmable alarms and other protection............................
Depending on the thresholds and time delays set using the keypad or remotely
using the COM option, the Micrologic P control unit monitors currents and voltage,power, frequency and the phase sequence. Each threshold overrun is signalled
remotely via the COM option. Each threshold overrun may be combined with
tripping (protection) or an indication carried out by an optional M2C or M6C
programmable contact (alarm), or both (protection and alarm).
Load shedding and reconnection........................................
Load shedding and reconnection parameters may be set according to the power orthe current flowing through the circuit breaker. Load shedding is carr ied out by a
supervisor via the COM option or by an M2C or M6C programmable contact.
Measurements .......................................................................
The Micrologic P control unit calculates in real time all the electrical values (V, A,W, VAR, VA, Wh, VARh, VAh, Hz), power factors and crest factors.
The Micrologic P control unit also calculates demand current and demand powerover an adjustable time period. Each measurement is associated with a minimeterand a maximeter.
In the event of tripping on a fault, the interrupted current is stored. The optional
external power supply makes it possible to display the value with the circuit breakeropen or not supplied.
Histories and maintenance indicators ................................
The last ten trips and alarms are recorded in two separate history files.Maintenance indications (contact wear, operation cycles, etc.) are recorded for
local access.
Indication option via programmable contacts
The M2C (two contacts) and M6C (six contacts) auxiliary contacts may be used tosignal threshold overruns or status changes. They can be programmed using the
keypad on the Micrologic P control unit or remotely using the COM option.
Communication option (COM)
The communication option may be used to:remotely read and set parameters for the protection functions
transmit all the calculated indicators and measurements
signal the causes of tripping and alarms
consult the history files and the maintenance-indicator register.
maximeter reset.An event log and a maintenance register, stored in control-unit memory but notavailable locally, may be accessed in addition via the COM option.

Functionsand characteristics
Navigation from one display to another is intuitive. The six buttons on the keypadprovide access to the menus and easy selection of values. When the setting cover
is closed, the keypad may no longer be used to access the protection settings, but
still provides access to the displays for measurements, histories, indicators, etc.
Measurements .......................................................................
Instantaneous values
The value displayed on the screen is refreshed every second.
Minimum and maximum values of measurements are stored in memory(minimeters and maximeters).

Demand meteringThe demand is calculated over a fixed or sliding time window that may be
programmed from 5 to 60 minutes. According to the contract signed with the powersupplier, an indicator associated with a load shedding function makes it possible to
avoid or minimise the costs of overrunning the subscribed power. Maximum
demand values are systematically stored and time stamped (maximeter).

Additional technical characteristicsSetting the display languageSystem messages may be displayed in six different languages. The desired language isselected via the keypad.
Protection functionsAll current-based protection functions require no auxiliary source. Voltage-basedprotection functions are connected to AC power via a voltage measurement input builtinto the circuit breaker.
Measurement functionsMeasurement functions are independent of the protection functions.The high-accuracy measurement module operates independently of the protectionmodule, while remaining synchronised with protection events.
Measurement-calculation modemeasurement functions implement the new "zero blind time" concept which consists incontinuously measuring signals at a high sampling rate. The traditional "blind window"used to process samples no longer exists. This method ensures accurate energycalculations even for highly variable loads (welding machines, robots, etc.).
energies are calculated on the basis of the instantaneous power values, in twomanners:vthe traditional mode where only positive (consumed) energies are consideredvthe signed mode where the positive (consumed) and negative (supplied) energies areconsidered separately.

The maximeters and minimeters are available only via the COM option for use with
a supervisor.
Waveform captureThe Micrologic H control unit stores the last 4 cycles of each instantaneous current
or voltage measurement. On request or automatically on programmed events, thecontrol unit stores the waveforms. The waveforms may be displayed in the form of
oscillograms by a supervisor via the COM option. Definition is 64 points per cycle.
Enhanced alarm programmingEach instantaneous value can be compared to user-set high and low thresholds.Overrun of a threshold generates an alarm. An alarm or combinations of alarmscan be linked to programmable actions, including circuit-breaker opening,
activation of a M2C or M6C contact, selective recording of measurements in a log,
waveform capture, etc.
Event log and maintenance registersThe Micrologic H offers the same event log and maintenance register functions as
the Micrologic P.
Additional technical characteristicsSetting the display languageSystem messages may be displayed in six different languages. The desired language isselected via the keypad.
Protection functionsAll current-based protection functions require no auxiliary source. Voltage-basedprotection functions are connected to AC power via a voltage measurement input builtinto the circuit breaker.
Measurement functionsMeasurement functions are independent of the protection functions.The high-accuracy measurement module operates independently of the protectionmodule, while remaining synchronised with protection events.
Measurement-calculation mode
An analogue calculation function dedicated to measurements enhances the accuracy ofharmonic calculations and the power-quality indicators. The Micrologic H control unitcalculates electrical magnitudes using 1.5 x In dynamics (20 x In for Micrologic P).Measurement functions implement the new "zero blind time" conceptEnergies are calculated on the basis of the instantaneous power values, in the traditionaland signed modes.Harmonic components are calculated using the discrete Fourier transform (DFT).
Accuracy of measurements (including sensors)voltage (V) 1%current (A) 1.5%frequency (Hz) 0.1 Hzpower (W) and energy (Wh) 2.5%total harmonic distortion 1%
Stored informationThe fine-setting adjustments, the last 100 events and the maintenance register remain inthe control-unit memory even when power is lost.
Time-stampingTime-stamping is activated as soon as time is set manually or by a supervisor no
external power supply module is required (max. drift of 1 hour per year).ResetAn individual reset, via the keypad or remotely, acts on alarms, minimum and maximumdata, peak values, the counters and the indicators.

External sensorsExternal sensor for earth-fault and neutral protectionThe sensors, used with the 3P circuit breakers, are installed on the neutral
conductor for:neutral protection (with Micrologic P and H)residual type earth-fault protection (with Micrologic A, P and H)..
The rating of the sensor (CT) must be compatible with the rating of the circuit breaker:NT06 to NT16: TC 400/1600NW08 to NW20: TC 400/2000NW25 to NW40: TC 1000/4000NW40b to NW63: TC 2000/6300.
For oversized neutral protection the sensor rating must be compatible with themeasurement range: 1,6 x IN (available up to NW 40 and NT 16).
Rectangular sensor for earth-leakage protectionThe sensor is installed around the busbars (phases + neutral) to detect the zero-phase sequence current required for the earth-leakage protection. Rectangularsensors are available in two sizes.Inside dimensions (mm)
280 x 115 up to 1600 A for Masterpact NT and NW470 x 160 up to 4000 A for Masterpact NW.
External sensor for source ground return protectionThe sensor is installed around the connection of the transformer neutral point toearth and connects to the Micrologic 6.0 control unit via an MDGF module toprovide the source ground return (SGR) protection.
Voltage measurement inputsVoltage measurement inputs are required for power measurements (Micrologic Por H) and for earth-leakage protection (Micrologic 7...).As standard, the control unit is supplied by internal voltage measurement inputsplaced downstream of the pole for voltages between 100 and 690 V AC. Onrequest, it is possible to replace the internal voltage measurement inputs by anexternal voltage input (PTE option) which enables the control unit to draw powerdirectly from the distribution system upstream of the circuit breaker. An 3 m cablewith ferrite comes with this PTE option.
Long-time rating plugFour interchangeable plugs may be used to limit the long-time threshold settingrange for higher accuracy.The time delay settings indicated on the plugs are for an overload of 6 Ir (for furtherdetails, see the characteristics on pages 19 and 21).As standard, control units are equipped with the 0.4 to 1 plug.
Setting rangesstandard Ir = In x 0,4 0.5 0.6 0.7 0.8 0.9 0.95 0.98 1
low-setting option Ir = In x 0.4 0.45 0.50 0.55 0.60 0.65 0.70 0.75 0.8
high-setting option Ir = In x 0.80 0.82 0.85 0.88 0.90 0.92 0.95 0.98 1
off plug no long-time protection (Ir = In for Isd setting)
Important: Long-time rating plugs must always be removed before carrying outinsulation or dielectric withstand tests.
External power-supply moduleThe external power-supply module makes it possible to use the display even if thecircuit breaker is open or not supplied (for the exact conditions of use, see the"electrical diagrams" part of this catalogue).
This module powers both the control unit (100 mA) and the M2C and M6Cprogrammable contacts (100 mA).
With the Micrologic A control unit, this module makes it possible to display currentsof less than 20% of In.With the Micrologic P and H, it can be used to display fault currents after tripping.
Characteristicspower supply:v 110/130, 200/240, 380/415 V AC (+ 10% - 15%), consumption 10 VAv 24/30, 48/60, 100/125 V DC (+20% -20%), consumption 10 Woutput voltage: 24 V DC; power delivered: 5 W / 5 VAripple < 5%Dielectric withstand : 3 kV rms between input/output.
Battery moduleThe battery module makes it possible to use the display even if the power supply tothe Micrologic control unit is interrupted and still commucating with the supervisor.
Characteristics:battery run-time: 12 hours (approximately)mounted on vertical backplate or symmetrical rail.
