The Eaton Industries NZMB S power circuit breaker is rated for 100A continuous current, with a nominal disconnect capacity of 53kA at 400. It has an adjustable overload protection range of 600 – 1000A, and an adjustable instantaneous short circuit range of 600 – 1000A. The primary circuit is connected via a screw connection, and the unit is designed with a three-pole layout. This circuit breaker series falls into a compact size category that is suitable for global use due to its modular and flexible mounting options. It comes with a magnetic short-circuit release feature which works in conjunction with an overload relay, however it lacks an overload trip with short-circuit release. This unit complies with UL/CSA and IEC regulations, as indicated on its IEC rating plate.
