The Eaton Industries MCCB motor protection switch, with dimensions of 90×84.5x145mm, has a nominal continuous current Iu of 40A and an operating voltage of 690V. Integrated into a built-in device insert, it features a unique connection way of the main current circuit and uses magnetic switch-off technology. This device also offers a protection degree of IP20. It is similar to the NZM series which are compact and fulfill all the requirements of the AC-3 switching category. These breakers come with a magnetic short-circuit release in connection with overload relay, and also provide short-circuit release without overload trip, ensuring versatile mounting options and efficient operation.
