Abstract: An electrical apparatus including a protective device with an electrically insulating bushing having an axially extending inner bore and terminal members disposed adjacent to the opposite ends of the bushing. A fusible element or fuse link is disposed in and spaced from the inner bore of the bushing and is electrically connected between the terminal members. A pulverulent or granular arc quenching material substantially fills the space between the fusible element and the inner bore of the bushing which includes at its outer periphery axially intermediate the ends of the bushing a portion which is adapted to receive a supporting means for the bushing on the wall or cover of the enclosure of the associated electrical apparatus.

Abstract: A rotary switch with separable stationary and movable contacts and having a shaft which is rotatable to actuate the movement of the movable contacts between first and second operating positions. A spring return mechanism biases the shaft toward a first angular position corresponding to the first operating position of the movable contacts. A lever arm is mounted on the shaft for movement therewith and carries a magnetic armature. A stationary magnetic structure is disposed adjacent to the shaft and includes a permanent magnet member. When the shaft is rotated to a second angular position which corresponds to the second operating position, the magnetic armature engages or seats against the stationary magnetic structure and the magnetic flux from the permanent magnet member passes through the armature to magnetically latch the shaft in the second angular position against the influence of the spring return mechanism. An electromagnetic coil or winding is disposed on the stationary magnetic structure and is energizable to provide a magnetic flux which opposes the magnetic flux which passes through the armature from the permanent magnet member to thereby release the armature and the shaft which is then actuated to the first angular position by the spring return mechanism.

Abstract: A high-voltage protective device comprising a hollow, generally cylindrical, electrically insulating member having an inner bore. A pair of terminal members is mounted on the insulating member adjacent to the opposite ends. One or more fuse links or fusible elements is disposed in the inner bore and spaced therefrom with each fuse link being connected between the associated terminal members. A finely divided or pulverulent arc quenching material substantially fills the space between each fuse link and the inner bore of the associated insulating member. A supporting means is secured to said insulating member at only one location which is axially intermediate the ends of said insulating member.
