Technical Data according to IEC/EN 60947-1, 60947-2, 60947-4-1 and VDE 0660

 

This table shows the rated ultimate short-circuit breaking capacity Icu and the rated service short-circuit breaking capacity Icsof the J7MN circuit-breakers with different operational voltages as a function of the rated current In of the circuit-breakers.

The circuit-breakers can be fed at the top or bottom supply terminals without any reduction of the rated data.

If the short-circuit current exceeds the rated short-circuit breaking capacity of the circuit-breaker specified in the tables at the installation point, a back-up fuse is to be used.

The maximum rated current for the back-up fuse is specified in the tables. These fuses are only suitable for the short-circuit-currents as indicated on the fuses.
