Westinghouse 01-0112 Contactor 30A 24V 1 Pole Spst Ac Heat Pump

Product Description

The WESTINGHOUSE 01-0112 is a single-pole, single-throw (SPST) contactor rated at 30 amps and 24 volts, designed for residential air conditioning and heat pump applications. A contactor is an electrically controlled switch that cycles compressor and condenser fan circuits on and off in response to thermostat signals. The 01-0112 uses a 24-volt coil — standard for low-voltage residential HVAC control circuits — and its 30-amp contact rating handles the inrush and running current demands of typical residential compressor loads.

This contactor is intended for use in residential split-system air conditioners and heat pumps, typically installed inside the outdoor condensing unit. It serves as the primary switching device that energizes the compressor and condenser fan motor when the control board or thermostat sends a 24-volt signal. HVAC technicians encounter this component routinely during seasonal startups, no-cooling calls, and compressor diagnostics. It is a common replacement part in service situations where the coil has failed, the contacts are pitted or welded, or the unit fails to start.

Key Features

• 30-amp contact rating suitable for residential compressor and condenser fan loads
• 24-volt coil voltage matches standard low-voltage residential HVAC control circuits
• 1-pole SPST configuration for single-leg switching of compressor circuits
• Designed as an OEM-style replacement for residential air conditioner and heat pump outdoor units

Compatibility

Designed for use in residential air conditioners and heat pumps as stated by the manufacturer. Verify coil voltage, contact amperage, pole count, and physical mounting dimensions against the existing contactor before installation.

Installation Notes

Contactor replacement is performed by licensed HVAC technicians. Disconnect and lock out all power to the outdoor condensing unit at the disconnect box and the main panel before beginning work. Allow capacitors in the unit to discharge before handling any wiring. Follow NEC requirements for disconnect means and wire sizing when reinstalling the condensing unit cover.
