The Eaton Industries MCCB motor protection switch is a compact device with dimensions of 90x88x165.5mm. This built-in device has a nominal continuous current Iu of 5A and uses magnetic switch-off technology. It has a protection grade of IP20 and operates at a voltage of 440V. The NZM..-S..CNA circuit breakers series is designed to cover all application cases with just four compact sizes and offers flexibility with its modular function groups. The device features a magnetic short-circuit release in association with an overload relay and lacks overload trip in the event of a short circuit. It conforms to UL/CSA as well as IEC regulations, as shown in the IEC switching performance values on the rating plate.
