Resetting the Circuit Breakers
The electronic trip unit will open the circuit breaker in the case of a drive
overload/overcurrent condition. When a voltage drop (U < 0.7 x Un) or loss of
the main supply occurs, the undervoltage release coil of the circuit breakers will
open. The trip indicator contacts of the circuit breakers are connected in series.
Therefore, if one circuit breakers trips due to an undervoltage or overload/
overcurrent condition, all circuit breakers will open/trip.
If the circuit breakers have opened due to an overcurrent fault, the condition that
caused the fault must be corrected and the fault cleared before the circuit breakers
can be reset and the drive started. In this case, see Charging the MCCB Motor
