An electrical protective device that includes a reset mechanism uses a resistor body to act as a hold-off to a spring driven lockout for the reset mechanism. According to one aspect of the present invention, a pusher assembly generally comprises a body portion ; first window formed in the body portion; second window formed in the body portion adjacent to the first window, the second window being wider than the first window. In one embodiment, the pacing system initiates cardiac protection pacing sequences including at least one postconditioning sequence to protect the heart from a detected ischemic event and a plurality prophylactic preconditioning sequences to protect the heart from probable future ischemic events. The gate electrode is formed in the narrow recess and in Schottky contact with the Schottky layer.
