Overview

This OEM 2-pole definite purpose contactor for the ICP / Tempstar / Heil RGS101HRBB0AAAA system is available in 30A (part 1178074) and 40A (part 1178211) ratings, both with a 24V control coil. The contactor is the electrically operated switch that energizes the compressor and condenser fan motor when the thermostat calls for cooling. The 24V coil pulls the contacts closed to pass line voltage to the load. Contactors are high-wear components — the silver contacts pit, burn, and weld over thousands of cycles, causing failed starts or a unit that won't shut off.
