Mars Double-Pole Contactor HVAC Relay

The Mars Double-Pole Contactor HVAC Relay line gives heating, ventilation, air conditioning and refrigeration systems a dependable way to switch power to loads such as compressors, condenser fan motors and blower motors. Each contactor (also called a contactor relay or HVAC contactor) uses a low-voltage coil to close its power contacts, so a thermostat or control board can safely control higher-current equipment.

Key Features:

• Double-pole contactor design that switches line power for HVAC equipment
• Coil-operated contacts for control from a thermostat or control circuit
• Suited to residential and light commercial air conditioning, heat pump and refrigeration applications
• Available in multiple coil voltage and current ratings within the line
• Made by Mars, a long-established name in HVAC/R replacement electrical components

This contactor line is a practical replacement part for worn or pitted contacts and failed coils, and it helps restore reliable system start-up and operation. Check the specifications listed for each individual part number to confirm the electrical ratings you need.
