The Eaton Industries NZMN S power circuit breaker delivers a nominal continuous current Iu of 63A and a nominal breaking capacity Icu of 105kA at 400V. It is designed with an adjustable overload protection range from 380 to 630A and an undelayed short circuit setting range from 380 to 630A. The main circuit connection is a screw connection, featuring three poles. Notably, this circuit breaker is part of the NZM..-S series suitable for the IEC market. Its compact design comes in only four sizes, allowing flexible mounting by using modular function groups. It further includes a magnetic short-circuit release in collaboration with an overload relay and a short-circuit release without an overload trip. This circuit breaker meets all requirements of the AC-3 switching category.
