Abstract
A self-resetting circuit overcurrent protection device comprises two or more flat positive temperature coefficient (PTC) elements, each comprising a layer of PTC material sandwiched between two metal plates, disposed in a parallel, overlapping configuration and connected in electrical parallel. The resulting circuit protection device has a hold current equal to the sum of the hold currents of the component PTC elements, while having a surface area no greater than that of a PTC device comprising only one of the component PTC elements. In the preferred embodiment of the invention, two PTC elements are used and one of the metal plates belonging to each of the PTC elements has a blade terminal integrally formed therewith, the terminals being substantially identical in configuration to the terminals of a standard automotive fuse which the device is intended to replace.
