The automatic transfer switch change over between two powers.One is noraml power and another one is reserve power.When the normal power is abnormal it will automatically change over to the reserve power.
When the normal power restored ,it will change over the load back to the normal power
and cut off the reserve power.
Different ATS has different function :
Category one :They only have basic change over power function.
Category two :They do not only have the change over function ,but also have overvoltage,
undervoltage,lose phases protection,fire protection function and so on
Category three:Some ATS have controller.
HYCQ5-63G is terminal type automatic transfer device. It’s suitable for 3 phases 4 wires (or 1 phase 1 wire) dual power grid with AC 50/60Hz, rated voltage 400V/230V 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 automatic transfer switch conforms to IEC60947-6-1 and GB/T14048.11
