The Eaton Industries NZMN S power circuit breaker offers a nominal continuous current Iu of 50A and a nominal switching capacity Icu at 400 105kA. It features an adjustable overload protection range of 300-500A and an instant short circuit setting range of 300-500A. With a screw connection for the main current circuit, this three-pole breaker complies with UL/CSA and IEC regulations, as stated on its rating plate. The compact structure of the NZM..-S..CNA series breaker ensures adaptability in mounting, equipped with a magnetic short-circuit release in connection with an overload relay, and a short-circuit release lacking an overload trip.
