Description
Product Summary
The Supco DP401203 Contactor 40A 120V 3 Pole is a professional-grade replacement part from Supco (Sealed Unit Parts Co.), a trusted name in HVAC/R and appliance parts since 1945. Supco® contactors are designed for use in HVAC&R systems. These contactors are available in 1.5, 2 and 3 pole configurations from 20 through 90 full amps. A compact universal design allows replacement of the most common brands.
Definite-purpose contactors switch high-voltage power to the compressor and condenser fan when the thermostat calls for cooling or heating. Pitted, welded, or chattering contacts are a leading cause of no-cool calls and short compressor life. Match the pole count, full-load amp (FLA) rating, and coil voltage (typically 24VAC) of the original.
Key Features
- CSA approved
- Economically priced
- Interchangeable mounting with many competitive contactors
- Silver cadmium oxide contacts
- Space saving dimensions allow for smaller panels and more wiring room
- UL® Recognized
- WARNING: Prop 65 info
