Multipole electrical circuit breaker with improved interchangeable trip units |
摘要 |
A molded case multi-pole circuit breaker comprises an interchangeable trip unit having a magnetic circuit surrounding a main stationary conductor and provided with a U-shaped core secured to circuit-breaker assembly and a magnetic rod fastener to the trip unit. The rod is inserted between the legs of the core, and a single turn secondary winding surrounds the rod. A bimetal is attached to the winding, and the thermal tripping characteristics are independent of the relative position of the magnetic core and rod.
