Abstract: A non-current limiting vacuum fuse employs a fusible assembly having a pair of electrodes and a fusible element that is situated therebetween. The fusible assembly is a rigid, self-supporting unitary structure that is brazed to an envelope when manufactured inside a vacuum furnace. The fuse provides improved interruption capability and/or a higher voltage rating at reduced cost. The fuse may be used individually, or a plurality of the fuses can be connected together in series to provide enhanced interruption capability and/or a higher voltage rating. The fuse can be connected in parallel with a current limiting fuse to form a vacuum current commutating fuse that provides the benefits of both types of fuses.

Abstract: A wire form rail adapter for use in connecting an electrical component to a mounting rail includes a wire form spring clip that is formed to provide both a connection portion and a spring portion. The connection portion is configured to selectively engage the mounting rail and retain the rail against the rail adapter. The spring portion is configured to provide a biasing force that urges the wire form spring clip toward a position in which the connection portion engages the mounting rail.
