The Eaton Industries NZMB S circuit-breaker is an adaptable device that caters to all application cases in four compact sizes. It’s intended for the IEC market and equipped with a screw connection for the main current circuit. It features a nominal continuous current Iu of 100A and a nominal trip-off capacity Icu of 53kA at 400 voltage. The device has an overload protection adjustment range of 600-1000A and an instantaneous short-circuit adjustment range of 600-1000A. Additionally, it operates with a magnetic short-circuit release in association with an overload relay, as well as a short-circuit release without overload trip. This 3-pole circuit breaker meets all requirements of AC-3 switching category.
