The Eaton Industries MCCB circuit-breaker, with dimensions of 185x346x260mm, is a built-in device with a screw connection for the main current circuit. It has a nominal continuous current Iu of 400A and uses magnetic interruption technology. It features a protection degree of IP20 and an operating voltage of 690V. This circuit breaker is a part of the NZM..-S series which offers flexibility in mounting due to modular function groups. It comes with a magnetic short-circuit release in connection with an overload relay, and also has a short-circuit release without overload trip. Moreover, it adheres to all the requirements of the AC-3 switching category.
