Abstract
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.
