Mars mars-17325 Definite Purpose Contactor 24V 2 Pole

Product Description

The MARS mars-17325 is a definite purpose contactor designed for switching loads in HVAC and refrigeration equipment. It features a 24 VAC coil and a 2-pole configuration, making it suited for controlling compressors, condenser fan motors, and other high-draw loads in light commercial and residential systems. Definite purpose contactors like this one are installed by HVAC technicians as part of new equipment builds or as direct replacements during service calls. The 24 VAC coil voltage is standard for low-voltage thermostat control circuits found across most split-system and packaged HVAC equipment.

This contactor is typically used in residential and light commercial air conditioning, heat pump, and refrigeration applications where reliable on-off switching of compressor or motor loads is required. It is well suited for rooftop units, split-system condensing units, and similar equipment that uses a 24 VAC control circuit. HVAC technicians often carry definite purpose contactors as standard service stock due to their frequency of replacement in the field.

Key Features

• 24 VAC coil voltage compatible with standard low-voltage thermostat control circuits
• 2-pole design for switching single-phase compressor and motor loads
• Definite purpose construction rated for repetitive switching in HVAC and refrigeration duty
• Common replacement part for service calls on residential and light commercial condensing units

Compatibility

Designed as an OEM-style replacement definite purpose contactor for residential and light commercial HVAC, heat pump, and refrigeration equipment using a 24 VAC control circuit and 2-pole contactor configuration.

Installation Notes

Installation should be performed by a licensed HVAC technician. Disconnect and lock out all power to the unit before removing or installing a contactor. Verify that the replacement coil voltage and pole configuration match the original contactor before energizing the system. Wire terminations should be made according to the existing wiring diagram on the equipment and in compliance with applicable NEC requirements.
