Overview

This genuine ICP OEM contactor, part number 1178074, is a 2-pole, 30-amp electromechanical contactor with a 24V control coil used in the RGS102SRCB0AAA. A contactor is a heavy-duty relay that switches the high-amperage line-voltage circuit feeding major loads. When the 24V coil is energized by the control board or thermostat, an electromagnet pulls the contacts closed, completing the power path; when the coil de-energizes, a spring opens them. Because the contacts make and break under load thousands of times, they eventually pit, burn, or weld. Worn contacts cause hard starts, chattering, dropped voltage, and in severe cases contacts that stick closed and will not let the system shut off. This 30A / 24V coil rating is a direct OEM match, ensuring correct pull-in voltage and contact capacity for your unit.
