Lennox Definite Purpose Contactor 25 Amp

The Lennox Definite Purpose Contactor, 25 Amp, is an electrical contactor (also called a relay or contactor switch) for HVAC equipment. It uses a low-voltage 24V control signal to switch high-current line voltage to loads such as compressors and condenser fan motors in air conditioning and heat pump systems.

Key Features:

• Definite purpose design for HVAC and refrigeration equipment
• 25 amp current rating
• 24V AC control coil, so it works with standard thermostat and control circuits
• When the low-voltage coil is energized, it closes the contacts and supplies power to the connected load
• Lennox-approved replacement for restoring reliable operation

A worn or pitted contactor can cause equipment that won't start, chattering, or intermittent operation. Replacing it with a Lennox contactor helps restore dependable switching. Choose the variant that matches your pole configuration and Lennox part number.
