Mars 62323 1 Pole Definite Purpose Contactor 30A 277V

Product Description

The MARS 62323 is a single-pole definite purpose contactor rated for 30 amps at 277 volts, designed for switching loads in HVAC and refrigeration control circuits. Part of the MARS 780 Series, this contactor is A2L refrigerant compliant, making it suited for systems using lower global warming potential refrigerants now entering widespread residential and light commercial deployment. Definite purpose contactors like this one are specified for duty cycles and load types common to compressor and condenser fan motor applications. Licensed HVAC technicians are the primary installers in both new-equipment and service-replacement scenarios.

This contactor is used in residential and light commercial HVAC equipment, particularly in condensing units, heat pumps, and packaged systems where single-pole switching of line-voltage loads is required. Its A2L compliance makes it relevant for equipment manufacturers and field technicians working with next-generation refrigerant platforms. It is well suited for compressor contactor replacement in single-phase condensing units operating on 277-volt circuits, such as those found in commercial HVAC applications.

Key Features

• Single-pole configuration for line-voltage load switching in HVAC systems
• 30-amp rating supports compressor and condenser fan motor loads
• 277-volt rating covers commercial single-phase and multi-wire branch circuit applications
• A2L refrigerant compliant for use in systems with low-GWP refrigerant platforms
• Part of the MARS 780 Series definite purpose contactor line

Compatibility

Designed as an OEM-style replacement for single-pole definite purpose contactors in residential and light commercial HVAC condensing units and packaged equipment requiring a 30-amp, 277-volt switching device.

Installation Notes

Installation should be performed by a licensed HVAC technician following applicable electrical codes, including NEC requirements for disconnecting means and overcurrent protection. Disconnect and lock out all power to the unit before removing the existing contactor or handling line-voltage terminals. Verify coil voltage requirements match the control circuit before energizing the replacement contactor. Inspect all wire terminations for proper seating and correct torque after installation.
