Ruud 42-25101-01 Heat Pump Contactor 32A 1 Pole 24V

Product Description

The RUUD 42-25101-01 is a single-pole heat pump contactor designed for use in residential and light commercial heat pump systems. It operates on a 24 volt AC coil and carries a full-load amperage (FLA) rating of 32 amps, with a resistive rating of 40 amps. The contactor switches line-voltage power to the compressor and outdoor fan motor on a call from the thermostat or control board. Licensed HVAC technicians install this part during routine service, compressor replacement, or contactor failure diagnosis. Its locked-rotor amperage (LRA) ratings of 180, 150, and 120 amps accommodate the high inrush current draw at compressor start.

This contactor is suited for single-pole switching applications in split-system heat pumps and air conditioners where a 24 volt control circuit energizes the coil. It fits a wide range of outdoor condensing units requiring a 1-pole, 32 amp FLA contactor. RUUD supplies this part under the ProTech components line for field replacement in residential and light commercial outdoor units. Technicians select this contactor when replacing a pitted, welded, or worn contactor as part of a scheduled maintenance or emergency repair call.

Key Features

• 24 volt AC coil for direct compatibility with standard low-voltage thermostat control circuits
• 32 amp FLA rating handles continuous compressor and fan motor loads
• 40 amp resistive rating provides additional capacity for resistive load applications
• LRA ratings of 180, 150, and 120 amps support high inrush current at compressor startup
• Single-pole design for line-voltage switching in heat pump outdoor units

Compatibility

Designed as an OEM-style replacement contactor for residential and light commercial heat pump and air conditioning outdoor units requiring a 1-pole, 24 volt AC coil contactor with a 32 amp FLA rating.

Installation Notes

Installation should be performed by a licensed HVAC technician following local codes and NFPA 70 (NEC) requirements. Disconnect and lock out all power to the outdoor unit at the disconnect box before removing the existing contactor. Confirm coil voltage, pole count, and amperage ratings match the unit nameplate before installing the replacement. Inspect all wire terminals and lugs for corrosion or heat damage and replace any damaged wiring before energizing the system.
