The Eaton Industries NZMN S Power Circuit Breaker, has a nominal continuous current of Iu 63A, and a nominal breaking capacity of Icu 105kA at 400. It features an overload protection range of 380-630A and an immediate short circuit range of 380-630A. Connection method for the main circuit is screw connection, and it operates on 3 poles. This compact-sized circuit breaker is globally compatible, offers flexibility in mounting choices and integrates a magnetic short-circuit release in conjunction with an overload relay and a short-circuit release lacking overload trip. The switches conform to UL/CSA and IEC regulations as indicated on the rating plate.
