Zusammenfassung:A self-recovery type closing electromagnet is disclosed. The self-recovery type closing electromagnet comprises a switching-closing coil, a self-recovery type fuse and a terminal; one end of the switching-closing coil is welded on the self-recovery type fuse; and the other end of the self-recovery type fuse and the other end of the switching-closing coil are connected with the terminal separately, and connected with a control loop. The self-recovery type closing electromagnet is simple in structure, safe, reliable and capable of realizing self recovery after the fuse is overheated, so that the rapid closing operation of a circuit breaker is effectively ensured; when voltage is applied to the control loop, the current passing through the coil is normal current within a short time; when fault occurs, the self-recovery type fuse cuts off the current with the continuity of the applied voltage so as to protect the coil before the coil is burnt; and the self-recovery type fuse can recover after a short time so as t
