If the configuration includes the "separate Mains 2" option, the protection devices recommended for Mains 1 and Mains 2 are the same as those of circuit breaker CB1 in the table above for Comet series 11 and Comet series 33.

For Comet series 31, the recommended protection devices are given in the table below:

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.
