Abstract

The circuit breaker electromagnetic propellant mechanism includes an electromagnetic body (7) and a paddle mounted to pivot about a hinge (21). There is a fixed contact (3) and a mobile contact support arm (5) mounted pivotally about a hinge (22). A hammer (9) is formed by an elongated piece inserted between the paddle (8) and the mobile contact support arm. The hinge (21) of the paddle (8) and the hinge (22) of the mobile contact arm (5) are situated on the same side w.r.t. the electromagnetic body (7). The hammer (9) is connected to the paddle (8) at an intermediate point between the hinge (21) of the paddle and the end region of the paddle, at a level which may be magnetically attracted to the electromagnetic body (7). <IMAGE>
