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

AC Power Contactor Control with 24V DC Relay In this setup, the 24V DC power supply energizes the relay coil, which in turn controls the contactor. When the relay coil is energized, the relay contacts close, completing the control circuit of the contactor and allowing the AC power to flow to the load. When the relay coil is de-energized, the relay contacts open, interrupting the control circuit and de-energizing the contactor, thereby turning off the load. CNC Electric can just be your trustwort

Power you do not see… but control you depend on every single day. Behind every HVAC system. Behind every compressor start. Behind every lighting panel. There is a component doing one critical job:safe switching. When the coil energizes, magnetism pulls the armature. Power contacts close. Current flows to the load. And when voltage stops? Everything opens instantly. That is how real electrical control protects motors, compressors, and entire systems. This is why professionals trust properly engin
