Trane 3-Pole Contactor

The Trane 3-Pole Contactor line gives HVAC systems a dependable way to switch power to compressors, condenser fan motors, and other major loads. Each one is an electrically controlled relay-style switch, also called a contactor or 3-pole relay. A low-voltage control signal from the thermostat or control board closes the contacts and sends line power to the equipment.

Key Features:

• Three-pole design switches all three legs of a three-phase load, and is also used on single-phase equipment
• Coil-actuated contacts that open and close on a control signal
• Built for the duty of residential and light commercial air conditioning and heat pump systems
• Replacement part designed to work with Trane equipment
• Available with different amperage ratings and coil voltages to match the application

Contacts wear over time from arcing, so a worn contactor can cause a unit that won't start, chattering, or a compressor or fan that fails to run. Replacing a pitted or failed contactor restores reliable switching and helps protect the equipment it controls. Shut off all power before servicing, and match the amperage rating and coil voltage to the original part.
