The Eaton Industries MCCB circuit-breaker, with dimensions of 140x166x275mm, is a built-in device with a fixed setup. It operates with a nominal continuous current Iu of 500A and uses screw connection for the main current circuit. The disconnecting technology is magnetic and it features an IP20-degree of protection. Its operating voltage is 690V. This compact circuit-breaker, available in four sizes, is suitable for the IEC market. It offers flexible mounting due to its modular function groups. The device comes with a magnetic short-circuit release in combination with an overload relay and a short-circuit release without an overload trip. The circuit-breaker meets all requirements of the switching category AC-3.
