Eaton NZMB1-M50 Circuit Breaker 3P 50A 25kA IEC – 265711

The Eaton Industries NZMB M power circuit breaker is designed to provide optimal performance with a nominal continuous current of 50A and a nominal disconnecting power of 53kA at 400. It features a setting range for overload protection of 300 – 500A, and a similar setting range for un-delayed short circuiting. Its main power circuit connectivity is facilitated through a screw connection, and it comes with 3 poles. It is part of the NZM..-M series, which is suitable for the IEC market. The breaker’s flexibility is enhanced by modular function groups. Additionally, it comes with thermomagnetic releases for motor protection and adheres to IEC/EN 60947-4-1 and IEC/EN 60947-2 circuit breakers requirements. Other features include phase-failure sensitivity and tripping class 10A.
