OVGLD-G 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.
