The Eaton Industries NZMN S circuit-breaker has a nominal continuous current of 80A, and a switching capacity of 105kA at 400V. Its overload protection range is adjustable from 480 to 800A, as is its instantaneous short circuit release range. The main circuit connection is a screw connection, and it has 3 poles. These compact and versatile circuit-breakers conform to UL/CSA and IEC standards, providing flexibility of installation with just four sizes. They’re modular with magnetic short-circuit release, yet lack an overload trip. The rating plate includes IEC switching performance values.
