Overview

This genuine OEM 2-pole, 30-amp definite-purpose contactor (part #1171554) with a 24V coil is the switching contactor for the ICP / Tempstar / Heil RGS300SDAA0AAAA system. A contactor is an electrically operated switch: when the 24VAC control signal energizes the coil, the contactor pulls in and its two 30A power poles close to deliver line voltage to the load. Over thousands of cycles the contacts pit, burn, or weld, and the coil can fail open. Symptoms include a unit that won't energize on a call, a contactor that buzzes loudly, or contacts that stick closed and leave the load running continuously. This OEM contactor matches the factory coil voltage, contact rating, and pole count for a direct, reliable replacement.
