PROBLEM TO BE SOLVED: To provide a current tripping device for a circuit breaker protecting circuits and having ability to function as a rectifier. SOLUTION: The tripping device (10) includes a current lead element (12), an anchor (40) having up-and-down positions, and an oscillator (23) having a first position and a second position. The oscillator permits the anchor to move into the down position in the first position, and blocks the anchor from moving into the down position in the second position. Additionally, a magnetic yoke (18) surrounds the current lead element and the anchor. A magnetic flux flowing through the magnetic yoke moves the anchor into the down position. Another magnetic yoke (16) surrounds the current lead element and the oscillator, and magnetic flux flowing through the magnetic yoke moves the oscillator into the first position or the second position.
