The Eaton Industries MCCB motor protection switch has a size of 90x88x145mm and an overload setting range of 50-63A. It’s suitable for built-in device construction with fixed installation, offering a nominal continuous current Iu of 63A, and uses a different connection method for the main current circuit. With a thermomagnetic trip technology, this device provides protection up to a level of IP20. Furthermore, it’s part of the NZM…-M series circuit-breakers which are compact and flexible in mounting, designed for the IEC market. They come with thermomagnetic releases for motor protection, display phase-failure sensitivity, and meet all requirements of the AC-3 switching category under the IEC/EN 60947-4-1 and IEC/EN 60947-2 standards.
