Mars mars-17315 Definite Purpose Contactor 30A 1P 24V

Product Description

The MARS mars-17315 is a definite purpose contactor designed for switching motor loads in HVAC and refrigeration equipment. It features a 24 VAC coil and is rated for 30 amps across a single pole configuration. Definite purpose contactors like this one are used to control the compressor, condenser fan motor, or other high-draw loads in response to a low-voltage control signal. Licensed HVAC technicians install this contactor as part of routine maintenance or component-level repair on cooling and refrigeration systems. Its compact footprint and standard coil voltage make it a straightforward replacement in many residential and light commercial applications.

This contactor is suited for residential and light commercial HVAC systems where a single-pole, 30-amp switching device is required. Typical install scenarios include split-system air conditioners, heat pumps, and packaged units where the thermostat or control board sends a 24 VAC signal to energize the contactor coil and close the load circuit. It is appropriate for use in condensing units and similar motor-control applications requiring a definite purpose switching device.

Key Features

• 24 VAC coil voltage for compatibility with standard low-voltage HVAC control circuits
• 30-amp load rating suitable for compressor and condenser fan motor switching
• Single-pole (1 pole) configuration for straightforward load-side wiring
• Definite purpose design optimized for repetitive switching duty in HVAC and refrigeration loads
• Compact form factor suitable for installation inside condensing unit control panels

Compatibility

Designed as an OEM-style replacement definite purpose contactor for residential and light commercial HVAC condensing units requiring a 1-pole, 30-amp, 24 VAC coil switching device.

Installation Notes

Installation should be performed by a licensed HVAC technician. Disconnect and lock out all power to the unit at the disconnect box before removing the existing contactor or handling load-side wiring. Verify that the replacement coil voltage and amperage rating match the system requirements before energizing. Consult NEC guidelines for proper conductor sizing and termination practices at the load terminals.
