Schneider universal circuit breaker "basic protection type" control unit
Micrologic 2.0, 5.0 and 6.0 control units protect the power supply circuit. Micrologic 5.0 and 6.0 provide time selectivity during short circuit.
◆Protection
The protection threshold and delay are adjusted with the adjusting knob.
Provide standard long delay tuning module.
●Overload protection
Real rms long delay protection.
Thermal memory: The accumulation of heat before and after the trip.
●Short circuit protection

In the delay, I2t (ON or OFF) can be selected.
●Neutral line protection
There is no neutral line protection on the 3-pole Schneider universal circuit breaker.
On the 4-pole Schneider universal circuit breaker, the neutral line protection can be set through the 3-position switch: the neutral line is unprotected (4P 3d), the neutral line is half-protected 0.5In (4P 3d+N/2) or medium Full protection of sex line In (4P 4d).
◆Instructions
The overload indication is realized by the alarm LED on the panel of the universal circuit breaker control unit. The LED lights up when the current exceeds the long delay setting threshold.

●Neutral line protection
There is no neutral line protection on the 3-pole universal circuit breaker.
On the 4-pole universal circuit breaker, the neutral line protection can be set by the 3-position switch: the neutral line has no protection (4P 3t), the neutral line protection is 0.5In (4P, 3t+N/2), the neutral line Protect In(4P 4t).
●Zone selective interlocking (ZSI)
ZSI is connected to multiple control units to provide complete selectivity of ground fault protection and short-time delay protection, without delay before tripping.
◆ Ammeter
Schneider universal circuit breaker Micrologic control unit A measures the true effective value (RMS) of the current.
The digital screen LCD continuously displays the maximum load phase current (lmax), or by pressing the navigation key, it can also display I1, I2, I3, IN, Ig, I∆n storage current (maximum) and set it.
The external power supply option can display current of <20%In.
If the current is lower than 0.05In, the measured value is meaningless. At 0.05 to 0.2In, the accuracy is 0.5% In+1.5% of reading.
●Overload alarm
The yellow LED on the panel of the Schneider circuit breaker control unit provides an overload alarm indication.
●Fault indication
LED lights indicate the type of fault.
1. Overload (Ir);
2. Short circuit (Isd, Ii);
3. Grounding (Ig);
4. Internal failure (Ap).
●Battery
After the fault occurs, the trip indicator LED light-stays on until the test/reset button is pressed. Under normal circumstances, the battery can power the LED for about 10 years.
●Test
Small or portable test devices can detect Schneider universal circuit breakers through the panel test hole, corresponding to the Micrologic 6.0A control unit, and the ground fault protection can be tested through the test button.

1. Current value required;
2. Voltage value: phase to phase, relative to ground, average value, unbalance coefficient;
3. Instantaneous power value: active, reactive, and apparent;
4. Power factor: PF;
5. Required power value: P required;
