ICP 2-Pole Contactor for RGS101STBB0AAAA — 30A 24V Coil | Ships Today

Overview

This is the OEM 2-pole definite purpose contactor (part number 1178074) for the ICP/Tempstar/Heil RGS101STBB0AAAA. The contactor is an electromagnetic switch: when the 24-volt control circuit energizes the coil, the contacts close and pass line-voltage power to the blower, inducer, or condensing components. Rated at 30 amps per pole with a 24V coil, it handles the inrush and running current of the unit's high-voltage loads. Typical failure symptoms include pitted or welded contacts, a buzzing or chattering coil, a unit that will not start despite a call for heat or cool, or contacts that stick closed and keep the equipment running continuously.

Specifications

Compatibility
