  • Patent number: 7924137
    Abstract: A fuse includes a fusible element and a body member encased within a heat-resistant housing. The fusible element is configured to open an electrical circuit coupled to a storage battery in response to an over-current in the electrical circuit. The housing is configured to contain an arc generated by the fusible element in response to the over-current and to shield the arc and the fusible element from ambient particles. Thus, the fuse is ignition protected. The body member includes an insulating material configured to interrupt the arc. The housing includes an opening configured to receive a terminal of the storage battery or a terminal of a mounting plate. An insulating material disposed about a first end of the mounting plate terminal is configured to electrically isolate the fuse and a power supply cable in the electrical circuit from the mounting plate terminal.
