CYQ1 series automatic transfer switch equipment (ATSE) is such a new product that integrates switch and logic control to truly realize the mechatronics; it applies at the distribution device of rated insulation voltage up to 1000V and rated frequency of 50Hz and rated voltage up to 660V and conventional heat current up to 3200A. to automatically transfer between the master power and the backup one in the power supply system or the two load devices and perform the secure isolation, wide used at the important occasions, e.g. hospital,marketplace,bank,highrise building,coal mine,communication department,iron mine,expressway, airport, product line and military facilities where the power interruption is taboo.

The switch equipment utilizes the control circuit to send various logic command to control the motor the turn of which, after speed reduction by gearcase, would drive the operating mechanism that accumulates the energy with the spring and performs the instantaneous release so as to quickly make and break the circuit or perform the circuit transfer and realize the secure isolation by obviously visual state.

The switch equipment could perform the full automatic operation, compulsively setting "0" remote control and emergency hand operation, moreover, it could perform detection and protection for phase lack, detection and protection for undervoltage, detection and protection for frequency, delay adjustment and electrical & mechanical interlock, etc.

The switch equipment features attractive appearance, novel and compact structure, small dimension and complete function, leading the counterpart.

Automatic transfer switch/ 3 phase automatic transfer switch/auto changeover switch

General:
CYQ1 series automatic transfer switch suitable for AC50HZ ,rated voltage 380V, DC rated voltage up 220V,rated electric current to 3200A.The switch is used in the infrequent on and off circuit.

Performance characteristics:
1.Full electrical engineering integrity which allows auto-control without external controller
2.The world high-tech logic control circuit with strong anti-jamming and no environmental interference.
3. The mechanism with spring powered accumulator applied in the switch main body, which allows for zero electrical arc by the feeler connection and disconnection.
4. The products have three poles, four poles , and (three poles + on and off neural pole)
5. Current grades can be divided into 100A160A250A630A1000A1250A1600A.2000A2500A3200A
6. 3 control modes(RBC)
7. R. Municipal power supply- Municipal power supply, automatic change and automatic recovery, protection of missed phase.
8. B. 125A up to 630A Municipal power supply-Municipal power supply, automatic change and automatic recovery, over voltage or lower-voltage  function.
9. C. Municipal power supply-oil generator, automatic change and automatic recovery. Having the functions of over-voltage or lower-voltage of phase shortage protection and frequency detection.

10. The switches can be padlocked to keep the position status
11. To use key to switch to select operation.
