ICP 2-Pole 30A Contactor for RGS120LDAA0AKAA — 24V Coil | Ships Today

Overview

This OEM 2-pole definite purpose contactor (Part No. 1178074) is the electromagnetic switch that energizes the compressor and condenser fan circuits in your ICP RGS120LDAA0AKAA system. When the thermostat calls, the 24V control coil pulls the contacts closed and passes line-voltage power to the load. Rated for 30 amps per pole with a 24V coil, it handles the high inrush current of HVAC motors without arcing. Failed contactors are one of the most common no-cool/no-heat callbacks — symptoms include a buzzing or chattering sound, pitted or welded contacts that won't open, and a unit that won't start even though the thermostat is calling.

Specifications

Compatibility
