Overview

This is the OEM 2-pole, 30-amp contactor with a 24-volt coil (part number 1178074) for the ICP / Heil / Tempstar RGS091LRBB0AAAA unit. A contactor is an electrically controlled switch: when the 24V control circuit energizes the coil, the contactor pulls in and passes line voltage to the load. Over time the contact points pit, burn, and weld from the constant arcing of switching high current, which causes the unit to chatter, fail to start, or fail to shut off. This direct-fit OEM contactor restores clean, reliable switching with 30A-rated 2-pole contacts and a standard 24VAC coil.
