A fuse clip unit is constructed with an entrance unit having positive reject stops which prevent insertion of all except a selected fuse which provides branch circuit protection of 200,000 amps R.M.S. interrupting capacity. The selected fuse has a unique end nib which moves the stops to open the entrance unit and permit insertion of the fuse. The entrance unit may be integral with the fuse clip or formed as a separate cover. The fuse clip unit is secured within an insulating and mounting housing having clip chambers. A safety cover is secured to the housing overlying the chambers and includes a side insertion opening for each chamber which prevents access to the reject stops and thereby prevents manual moving of the stops to circumvent the reject stops.

Fuse clip unit

A fuse clip apparatus is disclosed which provides connecting means for a blade type cartridge fuse in a circuit. The fuse clip includes an extruded terminal connector formed of aluminum or copper. The connector includes a terminal block for connection to an electrical lead. A blade contact portion is generally channel-shaped and includes a flat contact wall on one side of the extruded block and a spaced integral spring support wall. A beam plate spring is integrally formed with, or separately formed and interconnected to, the support wall. The illustrated spring is a double supported convex beam which extends from spaced support portions of the support wall toward the flat contact wall. The blade of the fuse is forced between the convex beam spring and the contact wall to hold the blade in firm engagement with the contact wall.

Contact clip apparatus for blade-type contacts

A connector assembly for providing contact between the conductors of an electric power cable and a plurality of leads. The connector assembly includes a distribution block connected to the leads, and a connector slidably mounted on the block for providing contact between the cable conductors and the block. The connector includes a split collar for receiving and clamping about the cable conductors and a pair of opposing legs projecting outwardly from the free ends thereof. The legs are slidably received within a channel formed along one side of the block for selective positioning thereon. A set screw secures the cable conductors within the connector and simultaneously fixes the location of the connector on the block and assures intimate contact of the connector with the block by spreading the legs of the connector to firmly engage the sides of the channel.
