1. A DC output solid state contactor assembly comprising:
i. at least one isolated semiconductor power module, the at least one power module having at least one supply lead connected thereto;
ii. at least one drive circuit connected to at least one chassis mount power module, the at least one drive circuit having at least one positive control input connection and an at least one negative control input connection;
iii. a plurality of load output power terminals, each of the plurality of load output power terminals for connecting to one of the at least one hot side of the circuit and one of the at least one low potential side of the circuit;
iv. a plurality of input/output terminals, each of the plurality of input/output terminals electrically connected to the at least one drive circuit and at least one supply lead of the at least one isolated power module;
v. a thermally conductive baseplate for conducting heat generated by the at least one isolated semiconductor power module to a panel mount surface; and
vi. an insulation barrier positioned between each of the plurality of load output power terminals.
