Reliance Electric 78093-3R is a three-pole DC contactor designed for switching resistive heating and battery loads in industrial DC power systems. This solenoid-operated unit uses front-mounted pressure-type terminals to simplify wiring and support organized wire-channel layouts, making panel integration straightforward. The 78093-3R can accommodate auxiliary contacts—NO, NC, or both—and is compatible with Reliance Electric side-mounting kits to add up to four additional auxiliary contact blocks without needing another DC contactor. Weighing about 11.45 lb (5.19 kg), it’s built for reliable operation in demanding control environments.
