Allied Air 28g86 Contactor Spst 24V 35A

Product Description

The ALLIED AIR 28g86 is a single-pole single-throw (SPST) contactor rated for 24-volt coil operation and 35-amp load switching. Contactors of this type serve as the primary switching device in HVAC systems, energizing compressors and condenser fan motors on a call for cooling. The 24-volt coil draws its signal from the low-voltage control circuit, while the line-voltage contacts handle the high-amperage load. Licensed HVAC technicians are the intended installers for this component.

This contactor is suited for residential and light commercial condensing units and heat pump outdoor sections where a single-pole switching arrangement is required. It is designed to handle the inrush and running current of compressors that fall within the 35-amp contact rating. The 24-volt coil makes it compatible with standard thermostat control circuits found across the majority of split-system and package-unit platforms.

Key Features

• SPST configuration switches one high-voltage leg for compressor or fan motor loads
• 24-volt coil integrates directly with standard low-voltage thermostat control circuits
• 35-amp contact rating handles typical residential compressor inrush and running current
• OEM-style replacement design for straightforward drop-in service calls

Compatibility

Designed as an OEM-style replacement contactor for residential and light commercial HVAC condensing units requiring an SPST 24-volt 35-amp switching device. Cross-reference part number 107638-04 when verifying fitment.

Installation Notes

Installation must be performed by a licensed HVAC technician. Disconnect and lock out all power at the disconnect box and the breaker panel before removing the existing contactor. Verify coil voltage and contact amperage ratings match the equipment nameplate before installing. Follow NEC guidelines for proper wire termination and enclosure reassembly.
