The RECTORSEAL n4116 is a 3-pole contactor rated at 40 amps and 24 volts, designed for use in HVACR electrical control circuits. Contactors of this type serve as the primary switching device that energizes compressors, condenser fan motors, and other high-draw loads in response to a low-voltage control signal. This unit includes integral lugs for direct wire termination, eliminating the need for separate compression connectors at the load terminals. It is installed by licensed HVAC technicians and electricians working on residential and light commercial cooling equipment.
This contactor is suited for installations where a 3-pole switching configuration is required, such as three-phase compressor loads or multi-leg single-phase applications in packaged units, split systems, and rooftop units. The 24-volt coil voltage is the standard control-circuit voltage used across most residential and light commercial HVACR equipment, making this a widely applicable replacement component for failed or worn contactors in the field.
Designed as an OEM-style replacement contactor for residential and light commercial HVACR systems requiring a 3-pole, 40-amp, 24-volt coil contactor with integral lugs.
Installation should be performed by a licensed HVAC technician or electrician. Disconnect and lock out all power to the unit at the disconnect box before removing the existing contactor or handling any wiring. Verify coil voltage and pole count match the original component before installation. Work on refrigerant-containing systems must comply with applicable EPA Section 608 regulations, and all electrical work must conform to the NEC and local codes.
