ABSTRACT:
A clip-on protection device for use with an over-voltage protector to protect sensitive apparatus including telephones. The device comprises a housing in which is disposed in electrically insulated spaced array, electrical contact means and head conduction means. Each one of these means is formed with fingers that extend from the housing. Movable elements are disposed within the housing. These movable elements include fusible spacers. The housing clips onto the over-voltage protector with the fingers engaging the respective electrodes thereof. A sustained overload condition causes the fusible spacers to fuse whereupon the movable elements operate to short the electrical contact means to ground.
