Abstract: The disclosed concept relates to compositions and methods for the manufacture of electrically resistive, thermally conductive electrical switching apparatus. The composition includes a polymer component and a nanofiber component. The thermal conductivity of the nanofiber component is higher than the thermal conductivity of the polymer component such that the electrical switching apparatus which includes the composition of the disclosed concept has improved heat dissipation as compared to an electrical switching apparatus constructed of the polymer component in the absence of the nanofiber component. Further, the disclosed concept relates to methods of towering the internal temperature of an electrically resistive, thermally conductive electrical switching apparatus by forming the internals of the apparatus, e.g., circuit breakers, and/or the enclosure from the composition of the disclosed concept.
