Special features

Maximum back-up fuse, if the expected short-circuit currents at the installation location exceed the switching capacity of the circuit breaker (Rated short-circuit breaking capacity Icn)

Rated current = rated uninterrupted current: 630 A

Reduced neutral conductor protection

Set value in neutral conductor is synchronous with set value Ir of main pole.

R.m.s. value measurement and “thermal memory”

Earth-fault release: Not dependent on mains and control voltages
