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
**0A**0A**0A**0A***0A***0A***0A.***0A***0A***0A
6. 3 control modes(RBC)
7. R. Municipal power supply- Municipal power supply, automatic
change and automatic recovery, protection of missed
phase.
8. B. **5A up to **0A Municipal power supply-Municipal power
supply, automatic change and automatic recovery, over voltage or
lower-voltage
