  • Fuse providing overcurrent and thermal protection
    Patent number: 9443688
    Abstract: A fuse in one embodiment includes first and second leads. A fuse element provides electrical communication between the first and second leads. The fuse element includes a material with a melting point of less than 250.degree. C. and acts as both an overcurrent fuse and a thermal fuse by melting when subjected to a predetermined current or upon reaching a predetermined temperature. A body houses the fuse element and portions of the first and second leads.
    Type: Grant

  • Double wound fusible element and associated fuse
    Patent number: 9117615
    Abstract: An improved fusible element for use within a circuit protection device is provided which includes a double wound fusible element configured to withstand high surge current associated with inductive and capacitive loads. The fusible element includes an insulated core having a longitudinal axis, a first wire wound about the core along the longitudinal axis of the core, and a second wire wound substantially orthogonally about a longitudinal axis of the first wire such that the fusible element is configured to withstand an over-current surge condition.
