CYQ3Z series automatic transfer switch(ATS) is Applicable to the three-phase four-line two-circuit power supply network with an AC power frequency of 50Hz, rated operational voltage of AC400V, and rated operational current of up to 630A, the NZ7 series automatic transfer switching equipment can automatically connect one or several loads from one power source to another to ensure the normal power supply of the load circuit.

CYQ3Z series Intelligent Automatic Transfer Switch/ATS Power changeover switch

1)CYQ3Z automatic transfer switching equipment (hereinafter referred to as ATSE) is made up of device body and

intelligent automatic controller two parts.

2) The device body is made up of two circuit breakers (refer to the technical parameters for model and

specification) that are equipped with electric operating mechanisms as well as accessories

(auxiliary alarm contact and so on) mechanical interlocking mechanism, electrical interlock

terminal block and so on, all the parts are installed on a metal plate.

3) Intelligent automatic controller is made up of novel singlechip as well as output and other modules.

4) The two parts are connected by aerial plug port and special shielded cable whose length is not over 2m

formed into intelligent control system whose control supply voltage is 220V, 50/60Hz.

5) ATSE has function of mechanical and electrical dual interlocking protection, guarantees safe and reliable

power supply.

6) It is able to finish automatic dual-power transfer in single-phase 220V system, three-phase three-wire system and three-phase four-wire system.
