The Eaton Industries MCCB motor protection switch is a compact device with dimensions of 105x149x195mm. This device operates on a 200A nominal continuous current and features an adjustable overload protection range of 100 – 200A. It is designed as a built-in unit with a screw connection method for the main circuit. Also, it comes with an electronic shutdown technique. This circuit breaker from the NZM..-ME..NA series covers all applications with only four sizes. The device is fully flexible due to its modular function groups. It has an electronic release for motor protection with phase failure sensitivity and conforms to both UL/CSA and IEC regulations. This device is designed for use in motor circuits with a contactor and has adjustable overload releases Ir and a time delay setting to manage current peaks tr:2-20s at 6xIr.
