The Eaton Industries MCCB motor protection circuit breaker is a compact device measuring 95x90x201mm, best suited for in-built installation. With a rated uninterrupted current of 80A, it employs a unique connection method for its main current circuit. The circuit breaker utilizes magnetic trip technology, offering an IP20 protection degree. Operating at a measurement voltage of 690V, the NZM series circuit breakers accommodate all applications with just four compact sizes, making mounting flexible with its modular function groups. It comprises a magnetic short-circuit release in combination with an overload relay and a short-circuit release devoid of an overload trip. These circuit-breakers fulfill all requirements of the AC-3 switching category.
