The Eaton Industries MCCB motor protection switch measures 95x90x201mm and is designed for mounting as an insertable device. With a nominal continuous current of 50A, its main circuit connection is unique. It employs magnetic tripping technology and offers an IP20-rated protection level. The operating voltage is 690V. This switch is part of the NZM..-S series of circuit breakers that cover all applications within four compact sizes and are apt for the IEC market. They feature flexible mounting due to modular function groups. The switch comes with magnetic short-circuit release linked with an overload relay and short-circuit release without overload tripping. They meet all requirements of the AC-3 switching category.
