The Eaton Industries NZMN M is a power circuit-breaker that has a nominal continuous current Iu of 80A and a nominal interrupting capacity Icu of 105kA at 400. It features a screw connection for the main circuit and is a 3-pole device. It has an overload protection setting range of 480 – 800A, and an instantaneous short-circuit trip range of 480 – 800A. The NZMN series circuit-breakers are compact, with a thermomagnetic release for motor protection. They also have phase-failure sensitivity, a tripping class of 10A, and meet all the requirements of the switching category AC-3, as stipulated by IEC/EN 60947-4-1 and IEC/EN 60947-2.
