Note:

The breaking capacity of the protection devices must be greater than the prospective short-circuit current.

Consult the Merlin Gerin Low Voltage Application Guide for further details.

Selection of the trip units for the circuit breakers installed upstream of the transformers must take the inrush currents (10 to 14In) into account.
