Description
Product Summary
The Supco SMC11 2 Pole Contactor is a professional-grade replacement part from Supco (Sealed Unit Parts Co.), a trusted name in HVAC/R and appliance parts since 1945. Designed to replace 2 pole, 30 amp contactors used in AC and electric heat applications to control the blower motors.
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.
