The Eaton Industries NZMN S power circuit breaker, with a nominal continuous current Iu of 160A and a nominal trip-off ability Icu of 105kA at 400, offers an adjustable range of overload protection from 1210 to 2000A. This product also provides an un-delayed short circuit adjustable range between 1210 and 2000A with a screw connection main circuit. This three-pole circuit breaker ensures flexibility in mounting based on modular function groups, and features a magnetic short-circuit release in connection with an overload relay, but lacks an overload trip in short-circuit release. It conforms to both UL/CSA and IEC regulations, with IEC switching performance values on its rating plate.
