摘要： A circuit interrupter has a pair of contacts, a self-restoring type current limiting element and a first electromagnetic trip device serially interconnected. The current limiting element is connected across a parallel connected resistor and a second electromagnetic trip device. Both trip devices have a common magnetic circuit including a single stationary core and a single movable iron piece. The first trip device responds to a shortcircuiting current flowing through it to open the contacts but the second trip device is operative to open the contacts only after the current limiting element has performed the operation of limiting a shortcircuiting current.
