A trip unit having a current leading element, an anchor having an up and a down position, and an oscillator having a first position and a second position. The oscillator in the first position permits the anchor to move into the down position, and the oscillator in the second position blocks the anchor from moving into the down position. Additionally, a magnetic yoke surrounds the current leading element and the anchor. A magnetic flux flowing through the magnetic yoke moves the anchor into the down position. A magnetic yoke surrounding the current leading element and the oscillator provides a magnetic flux flowing through the magnetic yoke moves the oscillator into the first position, or into the second position.
