AC Power Contactor Control with MY4N Relay The MY4N relay acts as an intermediary between the control signal and the power contactor, allowing for safe and controlled switching of the power circuit. By energizing and de-energizing the relay coil, the control circuit of the power contactor is completed or interrupted, providing reliable control over the power flow. CNC Electric can just be your trustworthy brand for business cooperation and household electrical demand. #cncelectric #cnc #motorcon

Automatically switch between normal power and standby power by one contactor A four-pole AC contactor can achieve dual power switching. When the AC contactor is working, the two sets of normally open contacts are closed and the normal power supply is supplied. When the AC contactor loses power, the two sets of normally closed contacts are reset and the standby power supply is supplied. . . . . . . . #powersupply #power #powerelectronics #powerengineering #powerforlife #electricalengineering #ele
