The circuit breaker uses the whole layout, carries on the unit modular design according to the function

The vacuum arc extinguishing chamber is driven by a unique variable direct drive mechanism.

The circuit breaker energy storage mechanism is simple and the function is highly integrated.

Good matching, can be used for JYN3, KYN3, KYN18C, XGN2, GG1A and other cabinet type

Complete specifications, into a series of convenient user selection

High technical parameters

In June 2000 in Holland KEMA through type test.
