The Eaton Industries MCCB Motor Protection Circuit Breaker measures 95x90x201mm and is designed for installation in an insert device construction design. It operates with a nominal continuous current of 63A, using a distinct main circuit connection method, and employs a magnetic trip mechanism. The device offers an IP20 degree of protection and operates at a voltage of 440V. The Series NZM circuit-breakers cover a wide range of applications through four compact sizes, focusing on the IEC market. They feature a modular design for flexible mounting, encompassing magnetic short-circuit release and an overload relay. The breakers are also equipped with short-circuit release without overload trip. They meet all requirements of the AC-3 switching category.
