摘要： A circuit breaker with an insulation device is formed of a molded case having side walls to form a chamber, a stationary contact member situated in the chamber and fixed on the molded case, a moving contact member movably connected to the molded case, a U-shaped magnetic driving core attached to the stationary contact member and having a pair of arms projecting outwardly from the stationary contact member, and an insulation cover. The side walls has slots therein, and the arms are situated inside the slots so that the outer surfaces of the arms are covered by the side walls of the molded case. The insulation cover has arm-shaped and board-shaped parts and is attached onto the outer surface of the stationary contact member. The board-shaped part covers the outer surface of the stationary contact member except the contact point, and the arm-shaped parts covers the inner surfaces of the arms of the magnetic driving core so that the inner and outer surfaces of the magnetic driving core are completely covered.

摘要： A circuit breaker having at least one phase or pole including a first movable arm having a first contact and a second movable arm having a second contact. The first arm is driven by a switching gear. The second arm is disposed opposite to the first movable arm such that the second contact contacts the first contact when a normal current flows. The first arm exerts an electromagnetic repulsive force in such a direction that the first and second arms repel each other to open the first second contacts when a current exceeds a predetermined value. The second arm is pivotally supported by a support angle fixed on a housing and is electrically connected via a flexible lead with a terminal also fixed on the housing. The support angle and the terminal are fitted to an insulator such that the support angles, the terminal and insulator are assembled in a unitary construction.
