Abstract:
1. A solid state relay having an internal heat dissipation device, the relay comprising: an electrically nonconductive housing defining a hollow cavity; elements having a potential for producing an arc, including but not limited to, a printed wiring board (PWB), electronic components of the solid state relay and the internal heat dissipation device; wherein the PWB supports the electronic components of the solid state relay including at least one solid state switching device, the solid state switching device being in thermal communication with at least one heat sink of the internal heat dissipation device, the at least one heat sink being in juxtaposed position with an internal surface of the housing, the housing and a thermally conductive potting material completely enclosing the PWB, the electronic components of the solid state relay and the heat dissipation device within the hollow cavity such that no potentially arc producing elements are exposed to the atmosphere surrounding the housing.
