The Eaton Industries MCCB motor protection switch, with dimensions of 90x88x165.5mm, is a built-in device with a steady nominal continuous current Iu of 3A. The switch operates through a magnetic circuit-breaking system and features a protection degree of IP20. It operates at a business voltage of 690V. The NZM series circuit breakers are designed for global usage with four compact sizes and flexible mounting due to modular function groups. The device is equipped with a magnetic short-circuit release in correlation with an overload relay and a short-circuit release lacking an overload trip. This switch complies with both UL/CSA and IEC regulations, with IEC switching performance values displayed on the rating plate for reference.
