Vacuum circuit breaker LS Industrial Systems

1. General
1) High reliability of the operating mechanism
- Separate design of the main circuit from the operating mechanism.
- Adopt the toggle link method.
- Improved the reliability of electric circuit.
- Adopt the rapid auto-reclosing method as a standard option. (O-0.3sec.-CO-3min.-CO)
2) High interrupting performance
- Make short of the interrupting time. (3cycles)
- Increase the rated short-circuit withstand characteristics. (1sec. to 3sec.)
3) Great operational safety
- Reinforce the insulation in the conduct, by adopting the molded housing in each phase.
- Built in the device making the contacts open first when draw in and out.
- Adopt the tulip-shape connection between the cradle and the VCB.
