Contact pitting... Contactor wear and tear happens when electrical arcing takes place. The heat causes carbon build up and pits the contacts. This can lead to welded contacts, higher compressor amps etc. The Copeland Company SureSwitch switches on the zero cross of the alternating current sine wave and avoids arcing which avoids the problems noted above. #hvac #hvacr #refrigeration #hvacsystem #hvaclife #hvacsystem #hvacinstallation #hvaclife #hvacjourneyman #hvacservice #hvaccontactor #hvactips
