Abstract
A surge protection device employing a controlled convection thermal disconnector in which a surge protective component, such as a metal oxide varistor, and a thermally responsive device, such as a thermal cut-off, are placed in separate, cross-ventilated chambers. An internal vent is positioned such that it prevents line-of-sight between the surge protective component and a mechanized portion of the thermally responsive device, in order to protect the thermally responsive device from hot surge protective component emissions from the surge protective component. An output vent is formed between the thermally responsive device and the exterior atmosphere to promote forced convective heat transfer from the surge protective component to the thermally responsive device during a thermal runaway condition, with the expanding gases in the surge protective component chamber providing the transfer impetus.
