Rcd hn51jd026 Contactor 1 Pole 24V 40 Fla Hvac

Product Description

The RCD hn51jd026 is a single-pole contactor designed for electrical load switching in residential and light commercial HVAC equipment. It operates on a 24-volt coil rated for 50/60 Hz and handles up to 40 amps full load amperage (FLA) and 50 amps resistive. The contactor controls power to compressors and condenser fan motors by opening and closing the high-voltage circuit in response to a low-voltage thermostat or control board signal. Licensed HVAC technicians install this part during routine maintenance, component failure diagnosis, or system commissioning. The compact form factor measures 3.5 inches long, 2.6 inches wide, and 2.2 inches tall.

This contactor is suited for air conditioners, heat pumps, and condensing units that require a single-pole switching configuration with a 24-volt control coil. It fits applications where the original equipment specified a 40 FLA, 50-amp resistive contactor. Common install scenarios include condenser unit compressor circuit replacement during a seasonal startup inspection or after a failed contactor diagnosis caused by pitted or welded contacts.

Key Features

• Single-pole design rated for 40 amps FLA and 50 amps resistive load
• 24-volt coil compatible with standard low-voltage thermostat control circuits
• Dual-frequency coil rated for both 50 Hz and 60 Hz systems
• Compact dimensions allow fitment in space-restricted condenser unit control compartments
• OEM-style replacement for air conditioner, heat pump, and condensing unit applications

Compatibility

Designed as an OEM-style replacement contactor for air conditioners, heat pumps, and condensing units requiring a single-pole, 24-volt coil contactor rated at 40 FLA and 50 amps resistive.

Installation Notes

Contactor replacement is performed by a licensed HVAC technician. Disconnect and lock out all power to the condensing unit at the disconnect box before opening the control compartment. Verify the replacement contactor coil voltage and pole configuration match the unit wiring diagram before installation. Inspect wiring terminals and wire gauge for signs of heat damage or corrosion and address any issues before energizing the unit.
