Features

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)
High interrupting performance
Make short of the interrupting time. (3cycles)
Increase the rated short-circuit withstand characteristics. (1sec. to 3sec.)
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.
