Auto Transfer Switches
Distinctive
- 1. Mold type, compact design
- This product broke away from the traditional assembly method and reduced the appearance dramatically by designing each phase into a stand-alone mold.
- 2. Intermediate shutdown
- The design allows a neutral position (OFF) using a trip device and switches after stable load and safety are secured.
- A=>off=>B , B=>off=>A , A=>off=>A , B=>off=>B A=>B, B=>A switching is also possible by using the operating instruction.
- 3. Detachable arc extinguishing chamber
- This innovative design enables it to check any wearing or damage of the contact point even during operation. The extinguishing capability is increased through an independent detachable arc extinguishing chamber.
