Mars mars-91422 Definite Purpose Contactor 120V 50A 2 Pole

Product Description

The MARS mars-91422 is a definite purpose contactor designed for switching loads in HVAC and refrigeration equipment. It features a 120-volt AC coil, a 50 full-load amp (FLA) rating, and a 2-pole configuration. Definite purpose contactors like this one are used to control compressors, condenser fan motors, and other high-draw loads in comfort cooling and refrigeration systems. Licensed HVAC technicians install this type of switching device during new equipment installation, component replacement, or system service calls.

This contactor is suited for residential and light commercial HVAC applications where a 2-pole, 120-volt coil contactor is specified. Common installation scenarios include rooftop units, split-system condensers, and packaged cooling equipment. The 50 FLA rating accommodates the starting and running current demands of single-phase compressor loads typical in residential and small commercial cooling systems.

Key Features

• 120-volt AC coil voltage for compatibility with standard low-voltage control circuits stepped up through a control transformer
• 50 FLA rating handles high inrush and sustained current of HVAC compressor loads
• 2-pole design for single-phase load switching
• Definite purpose construction rated specifically for HVAC and refrigeration duty cycles

Compatibility

Designed as an OEM-style replacement definite purpose contactor for residential and light commercial HVAC and refrigeration equipment requiring a 2-pole, 120-volt coil, 50 FLA contactor.

Installation Notes

Installation should be performed by a licensed HVAC technician. Disconnect and lock out all power to the unit before removing the existing contactor or making any wiring connections. Verify that the replacement contactor coil voltage and pole configuration match the equipment control circuit and load requirements before energizing the system. Follow all applicable NEC requirements and local codes when wiring line-side and load-side terminals.
