The Eaton Industries MCCB motor protection switch measures 105x149x195mm and features a built-in device fixed installation, a nominal continuous current Iu of 5A, and a screw connection for the main current circuit. It uses magnetic shutdown technology and has a protection degree of IP20. The operating voltage is 690V. The NZM..-S..CNA series circuit-breakers are compact and come in just four sizes, suitable for the global market. They allow for flexible mounting with its modular function groups. They have a magnetic short-circuit release in combination with an overload relay but lack an overload trip in the case of a short-circuit. These switches comply with both UL/CSA and IEC regulations, and the IEC switching performance values are marked on the rating plate.
