The Eaton Industries NZMN M circuit breaker, with a nominal continuous current Iu of 50A and a nominal switching capacity (Icu) of 105kA at 400V, provides an adjustable overload protection range of 300 – 500A and an adjustable instantaneous short circuit range of 300 – 500A. It features a screw connection method for the main current circuit and has 3 poles. This breaker is part of the NZM series, which caters to any application with just four compact sizes, making it suitable for the IEC market. The NZM series also offers phase-failure sensitivity and is equipped with thermomagnetic releases for motor protection. It meets all requirements of the AC-3 switching category as per IEC/EN 60947-4-1, IEC/EN 60947-2 standards.
