1. An electrical contactor comprising:
a contactor assembly comprising:
a housing;
an electromagnet coil and an electrically conductive core disposed within the housing, the electrically conductive core being movable relative to the electromagnet coil under influence of an electromagnetic force produced by the electromagnet coil; and
an electrically conductive contact bridge connected to a lower end of the electrically conductive core and movable with the electrically conductive core; and
an interrupter assembly comprising:
an electrically insulating base located below the electrically conductive bridge and having a trench formed in a top surface thereof;
an input bus bar and an output bus bar disposed on top of the electrically insulating base on opposing sides of the trench; and
a pyrotechnic interrupter disposed within the trench and comprising:
a plunger; and
a pyrotechnic ignitor disposed below the plunger;
wherein the electrically conductive contact bridge is movable between a first position, wherein the electrically conductive contact bridge provides an electrical connection between the input bus bar and the output bus bar, and a second position, wherein the electrically conductive contact bridge does not provide an electrical connection between the input bus bar and the output bus bar, and wherein, when the pyrotechnic ignitor is actuated, the plunger forcibly drives the electrically conductive contact bridge from the first position toward the second position.
