Eaton NZM2 Circuit Breaker 3P 40A 50KA UL/IEC – 269255

The Eaton Industries NZMN S circuit-breaker operates at a continuous current of 40A with a nominal cut-off capacity of 105kA at 400V. It has an overload protection adjustment range of 320-400A, and an instantaneous short circuit adjustment range of 320-400A. The circuit-breaker features a screw connection for the main current circuit and has three poles. Designed in four compact sizes for versatile mounting flexibility, it’s equipped with a magnetic short-circuit release in connection with an overload relay and a short-circuit release that lacks an overload trip. The switches comply with UL/CSA and IEC regulations, and the rating plate contains IEC switching performance values.
