ICP 2-Pole 30A 24V Contactor for RGS090SFBA0AAA — OEM | Ships Today

Overview

This genuine OEM 2-pole, 30-amp contactor (P/N 1178074) with a 24-volt coil is the electrical switching relay for the ICP / Tempstar / Heil RGS090SFBA0AAA system. When the 24V control circuit energizes the coil, the contactor's two main poles close and pass line voltage to the connected load. Over thousands of cycles the contacts pit, burn, and pull in weakly, causing chatter, dropped calls, or a unit that won't start. The coil itself can also open and fail to pull the contacts in at all. This direct-fit replacement restores reliable, full-amperage switching with the correct 30A rating and 24V coil so the system energizes cleanly on every call.
