Abstract

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.
