The Eaton Industries MCCB motor protection circuit breaker has dimensions of 95x90x201mm and features a built-in plug-in device build type. It has a nominal continuous current of 80A and utilizes a different connection method for the main current circuit. The switch-off technology is magnetic, offering an IP protection degree of IP20. It operates with a measured voltage of 440V. The NZM..-S series circuit-breakers are available in four compact sizes suitable for IEC market applications. They are flexible in mounting due to their modular function groups, and work with a magnetic short-circuit release in connection with an overload relay. The circuit-breakers also have a short-circuit release without an overload trip and fulfill all requirements of the AC-3 switching category.
