ICP 2-Pole Contactor for RGS101HEAA0AAAA — 30A/40A 24V Coil OEM | Ships Today

Overview

This OEM 2-pole definite-purpose contactor switches the line-voltage compressor and fan load for the ICP/Heil/Tempstar RGS101HEAA0AAAA system. When the thermostat closes a circuit, the 24-volt coil pulls in the contactor and energizes the outdoor unit; when the call ends, the coil drops out and breaks both legs of power. This listing covers both the 30-amp version (OEM part 1178074) and the 40-amp version (OEM part 1178211), each with a 24V control coil — match the amp rating to your equipment. Contactors are high-wear parts: their contacts pit, burn, and weld over thousands of cycles, leading to a unit that won't start, won't shut off, or chatters loudly.
