The Eaton Industries MCCB motor protection switch measures 90x88x165.5mm and is constructed for embedded installation. It has a nominal continuous current Iu of 12A and utilizes a unique connection method for the main current circuit. The switch-off technique is magnetic and has a protection degree of IP20. The operating voltage is 440V. The NZM..-S..CNA series circuit breakers suit all applications with just four compact sizes for global use. The modular function groups offer flexible mounting, with magnetic short-circuit release used in conjunction with an overload relay. It also features a short-circuit release without an overload trip. The switches comply with UL/CSA and IEC regulations, as indicated on the rating plate.
