The Eaton Industries MCCB Motor Protection Switch, with dimensions of 140x166x275mm, is designed for built-in device installation. It has a nominal continuous current Iu of 320A and the main circuit connection method is screw connection. The shutdown technology is magnetic and it has a protection degree (IP) of IP20. Its operating voltage (measurement voltage) is 690V. The NZM..-S series circuit breakers are suitable for all application with just four compact sizes for the IEC market. They feature modular function groups for flexible mounting and come with magnetic short-circuit release in connection with an overload relay. Also, they have short-circuit release without overload tip. Note that these circuit-breakers meet all requirements of the switching category AC-3.
