The Eaton Industries MCCB motor protection circuit breaker measures 95x90x201mm, with an overload setting range of 50 – 63A and a steady-state nominal current of 63A. It is a thermomagnetic device with a protection degree of IP20. The NZM..-M series circuit breakers are suitable for IEC market and come in four compact sizes to cover all applications. They offer flexible mounting due to their modular function groups and have thermomagnetic releases for motor protection. They also include phase-failure sensitivity, tripping class 10A, and are compliant with IEC/EN 60947-4-1, IEC/EN 60947-2 standards, meeting all requirements of the switching category AC-3.
