Trane Definite Purpose Contactor Coil HVAC Relay

This Trane definite purpose contactor is an HVAC relay. It switches line voltage to the compressor, condenser fan motor, and other loads in residential and light commercial air conditioning and heat pump systems. A low-voltage control coil activates the contactor. When the thermostat calls for cooling or heating, the coil energizes and closes the contacts. This lets the equipment start and stop reliably.

Key Features:

• Definite purpose design built for HVAC and refrigeration equipment duty
• Low-voltage 24V control coil for direct use with standard thermostat control circuits
• Multi-pole contact construction that switches the power supply to the connected load
• Made for use in Trane systems as a replacement or service part
• Offered in different pole and amperage configurations to suit the equipment being serviced

Replacing a worn or pitted contactor can help restore reliable system starting and prevent failures caused by burned contacts or a weak coil. Check the pole count, amperage rating, and coil voltage of your existing contactor against the variant you select. Always disconnect power before servicing.
