The Eaton Industries MCCB motor protection circuit breaker measures 140x166x275mm. It’s a built-in device with a nominal continuous current Iu 400A and utilizes the screw connection for the main circuit. It features magnetic trip technology and an IP20 protection degree. The operation voltage is 690V. Similarly, the NZM..-S circuit-breakers only require four compact sizes to cover all applications and are suitable for the IEC market. They offer modular function groups for flexibility in mounting and come with a magnetic short-circuit release in connection with an overload relay. They also have a short-circuit release without an overload trip function. These circuit-breakers fulfill all requirements of the AC-3 switching category.
