  • Patent number: 3960435
    Abstract: A fuse clip which accepts and retains the annularly grooved end cap of a current limiting ferrule cartridge fuse inserted therein, and which rejects the insertion of other classes of ferrule cartridge fuses. The fuse clip of the invention includes a central mounting portion and a pair of arm members extending in like direction from opposite sides of the mounting portion. The arm members include rejection means positioned on each arm member to co-act with the annular groove in the current limiting fuse end cap and allow it to be inserted and retained in the clip. The rejection means prevents the seating of a conventional fuse end cap in the clip and exerts a force on the cap tending to push it out of the clip.
