The Eaton Industries MCCB motor protection circuit breaker measures 95x90x201mm, and has an overload protection range of 32 – 40A. This device is designed to be built-in and utilizes a plug-in technology for easier installation. The nominal continuous current Iu is 40A. The main circuit connection mode is unique and the shutdown technology is thermomagnetic. It is also equipped with IP20 degree protection. The NZM..-M series of these circuit breakers are suitable for the IEC market and come in four compact sizes. These devices have modular function groups for flexible mounting and are equipped with thermomagnetic releases for motor protection. They are phase-failure sensitive, fall under tripping class 10A, and meet the requirements of IEC/EN 60947-4-1, IEC/EN 60947-2, and the AC-3 switching category.
