MARS-91422 2 Pole Definite Purpose Contactor 40A 120V

Product Description

The HEATCONTROLLERMARS91422 MARS-91422 is a 2-pole definite purpose contactor rated at 40 amps and 120 volts, designed for switching loads in refrigeration, air conditioning, and electric heating systems. It features box lug termination for secure conductor connections and a universal mounting base that simplifies field replacement. The straight-through wiring path and compact footprint reduce installation time. This contactor is installed by licensed HVAC technicians and electricians as part of system service or equipment replacement work.

This contactor is suited for residential and light commercial refrigeration, air conditioning, and electric heating applications. The 2-pole configuration handles both legs of the load circuit simultaneously, making it appropriate for compressor and condenser fan motor switching. The box lug termination accommodates a range of conductor sizes commonly found in field installations. Its universal mounting base allows it to drop in as a replacement for most competing definite purpose contactor brands without modification to the equipment mounting deck.

Key Features

• 2-pole definite purpose design rated for 40A load switching
• 120V coil voltage for standard low-voltage control circuit compatibility
• Box lug termination for secure, tool-tightened conductor connections
• Universal mounting base supports replacement of most contactor brands
• Straight-through wiring layout speeds installation in tight equipment cabinets
• Suitable for refrigeration, air conditioning, and electric heating system applications

Compatibility

Designed as an OEM-style replacement definite purpose contactor for refrigeration, air conditioning, and electric heating equipment using a 2-pole, 40A, 120V contactor. The universal mounting base is engineered to replace most contactor brands without additional hardware modification.

Installation Notes

Installation should be performed by a licensed HVAC technician or electrician. Disconnect and lock out all power to the unit before removing the existing contactor or making any wiring connections. Verify coil voltage and load ampacity ratings match the equipment specifications before installation. Refer to the equipment wiring diagram and applicable NEC requirements when sizing conductors and overcurrent protection for the load circuit.
