This OEM 40-amp definite purpose contactor (Tempstar part number 1176763) is the primary switching relay for your Tempstar TCH660GKA200 condensing unit. When the 24-volt coil is energized by the thermostat call for cooling, the contactor pulls in and closes its line-voltage contacts, sending power to the compressor and condenser fan motor. It is a 2-pole device rated at 40 amps with a 24V control coil. A failed contactor is one of the most common reasons an outdoor unit will not start, hum without engaging, or run continuously after the thermostat is satisfied. Pitted, welded, or burned contacts cause hard starts, chatter, and premature compressor wear.
