Application automatic transfer device: It's suitable for 3 phases 4 wires (or 1 phase 1 wire) dual power grid with AC 50HZ/60HZ, rated voltage 400V and rated current up to 63A.
When one power goes wrong (only test normal Phase A voltage and reserve Phase A voltage, only test loss voltage or loss phase),it will automatic connect one or several load circuits from one power to the other power automatically, to ensure normal power supply of load circuits.
The switch is mainly used for testing whether normal or spare power is normal or not.
When the normal power is abnormal, the spare power works at once, which therefore ensures the continuirty, reliability, and safety of power supply.

Product description
TIPS:
Dual power Automatic transfer switch can switch to Normal power or reserve power automatically.
Please noted that the switch can’t turn on or turn off the generator.
This
switch Normal power first. If normal power on, the switch will switch
to Normal power. If normal power off, and reserve power on, the switch
will switch to reserve power.
Wire:
Press the button to Automatic, the switch will switch to Normal power or reserve power automatically.
Press the button to Manual, Then you have to switch the Direction manually.
Application:
Terminal type automatic transfer device.
