The Eaton Industries MCCB motor protection switch measures 105x149x195mm and is ideal for solid-state device installation. It has a nominal continuous current Iu of 50A and screw connection for the main circuit. The switch uses magnetic tripping technology with an IP20 degree of protection. Its operating voltage is 690V. Comparable to the NZM..-S..CNA circuit-breakers, this device covers all applications with just four compact sizes while offering flexible mounting due to modular function groups. It pairs magnetic short-circuit release with an overload relay but lacks an overload trip in the short circuit release. The switch complies with UL/CSA and IEC regulations as noted on the IEC switching performance values on the rating plate.
