The Eaton Industries NZMN S power circuit-breaker has a nominal continuous current Iu of 200A and a nominal cut-off capacity Icu of 53kA at 400 volts. It features an overload protection setting range of 1210 – 2000A, and an instantaneous short circuit setting range of 1210 – 2000A. The connection method for the main current circuit is a screw connection and it contains 3 poles. This breaker is compact and covers all applications with just four sizes, making it suitable for the IEC market. It comes with a magnetic short-circuit release and offers flexibility in mounting due to its modular functional groups. It also has a short-circuit release without an overload trip. It fulfills all requirements of the AC-3 switching category.
