The Eaton Industries MCCB Motor Protection circuit-breaker, measuring 90x88x165.5mm, is a built-in device with a nominal continuous current of 2A. Its connection method is unique, featuring a magnetic switch-off technique and an IP20 degree of protection. It operates at a voltage of 440V. The NZM..-S..CNA series of circuit-breakers are compact but versatile, suitable for worldwide use. These are easily mountable due to their modular function groups and come equipped with a magnetic short-circuit release, along with an overload relay. However, the short-circuit release lacks an overload trip. For compliance, these switches conform to UL/CSA and IEC regulations, as indicated on the IEC switching performance values on the rating plate.
