Trane Contactor CTR02576

Trane CTR02576 2-Pole Definite Purpose Contactor | 40 Amp, 24 VAC Coil

Restore robust, heavy-duty electrical switching to your outdoor unit with the genuine Trane CTR02576 Definite Purpose Contactor. This premium Factory Authorized Part is a critical high-voltage control component engineered specifically for residential and commercial air conditioning condensing units and heat pump assemblies under the Trane and American Standard families of brands. Featuring a low-voltage 24 VAC control coil, this 2-pole contactor acts as the main heavy-duty relay, using your system's low-voltage thermostat loop to safely close the heavy electrical contacts and deliver high-amp line voltage directly to your outdoor compressor and condenser fan motor.

As a genuine factory OEM replacement component, the Trane CTR02576 ensures direct physical mounting and precise wiring termination, outperforming low-grade aftermarket alternatives that are prone to premature contact pitting or coil failures.
