ICP 2-Pole 30A Contactor for RGS121LTCB0AAA — 24V Coil | Ships Today

Overview

This OEM 2-pole, 30-amp contactor with a 24V coil (part #1178074) is the switching relay that energizes the high-voltage load on the ICP/Tempstar/Heil RGS121LTCB0AAA. When the 24V control circuit calls, the coil pulls the two main contacts closed to pass line voltage to the connected device. Contactors wear out from arcing each time the contacts open and close, leaving pitted or welded points and a coil that may hum or fail to pull in. A failing contactor causes hard starts, chattering, contacts that stick closed so the load won't shut off, or no operation at all. Replacing it with the exact 2-pole 30A 24V OEM part keeps the contact rating, coil voltage, and terminal layout matched to the factory wiring.

Specifications

Compatibility

Fits the ICP/Tempstar/Heil RGS121LTCB0AAA and other units specifying a 2-pole 30A contactor with a 24V coil. Verify pole count, amp rating, and coil voltage against the contactor you are replacing.

Installation Guide

1. Safety First — Disconnect power at the disconnect and breaker, then verify zero voltage across all terminals with a multimeter.
2. Access — Remove the electrical access panel.
3. Document — Photograph all line, load, and coil wiring before disconnecting.
4. Remove — Label and disconnect the wires, unbolt the old contactor from its mount, and remove it.
5. Install — Mount the new contactor and reconnect each lead to the matching terminal per your photo.
6. Test — Restore power, call for operation, and confirm the contactor pulls in cleanly and the load runs.

Signs You Need a Replacement

• Pitted, burned, or welded contacts
• Coil hums or buzzes but contacts won't pull in
• Load won't shut off because contacts are stuck closed
• Chattering or hard starts on each cycle
