YCQ9 series automatic transfer switch is suitable for AC 50Hz, rated working voltage
AC400V, rated operating current up to 630A three-phase four-wire dual-circuit
power supply grid, automatically connect one or several load circuits from one
power supply to another to ensure load normal power supply of the circuit. This
product is suitable for industrial, commercial, high-rise and residential buildings,
etc.more important places.
Standard: IEC 60947-6
1.Full range of dual-input single-output(up in and down out),convenient wiring and cost-saving.
2.Handle front operation for convenience and labor-saving
3.Compact size for space saving
4.Two controllers to meet different user needs
5.Low main circuit impedance and energy consumption
6.Reliable double interlock protection function
7.Instantaneous structural design, cleverly driven by dual springs, with a simple and stable structure
8.Rotary contact structure, circular arc extinguishing device design, good arc extinguishing performance, and long contact working life
●Control voltage: switch control voltage level is 230V
●Position indication: Indicates the position of the switch working state (I, O, II)
●Main body of the switch: the front part is the Ⅰ road, which is connected to the "normal power supply"; the rear part is the Ⅱ road,
which is connected to the “standby power supply”
