<p>An apparatus (300) for providing independent over-current protection to a plurality of electrical devices and a transient-voltage suppression system employing the apparatus. In one embodiment, the apparatus includes a non-conductive body (310) having a plurality of bores (311) extending through the body from a first portion (313) to a second portion (312) of the body, a plurality of fusible elements (320) corresponding to and disposed within the plurality of bores, each of the fusible elements having a first terminal (323) proximate to the first portion of the body and a second terminal (321) proximate to the second portion, and a common electrode (330) coupled to the first terminal of each of the plurality of fusible elements. The common electrode is couplable to a source of electrical power and the second terminals of each of the plurality of fusible elements are couplable to an electrical device, such as a metal oxide varistor in a transient-voltage suppression system. Each of the fusible elements are operative to open circuit when an electrical device coupled thereto causes an electrical current to flow through the fusible element in excess of a current rating of the fusible element.</p> |
