The Eaton Industries MCCB motor protection circuit breaker, measuring 95x90x201mm, has a setting range for overload protection of 63 – 80A with a nominal continuous current Iu of 80A. The device, designed for insertion installation, has a connection method for the main power circuit. The shutoff technology is thermomagnetic. It offers a protection grade of IP20. The NZM..-M series, in just four compact sizes, covers all application cases and is suitable for the IEC market. They offer flexibility in mounting thanks to modular function groups and come with thermomagnetic releases for motor protection. The circuit breakers have phase-failure sensitivity, tripping class 10A and fulfill the requirements of IEC/EN 60947-4-1, and IEC/EN 60947-2 of the AC-3 switching category.
