Popis:	Paper deals with the design and parameters of the new generation of vacuum circuit breakers (VCB) built around novel design of magnetic actuator. Actuator utilizes magnetic system with the serial magnetically hard alloy. The actuator is fixed in closed position by magnetic flux. In the open position it is fixed with the aid of opening spring. Single coil allows providing close and trip actions depending on the direction of the injected current. In each VCB pole separate actuator is installed. These actuators are linked with the synchronizing shaft providing control of auxiliary switches and interlocks. This design allows achieving high mechanical life and maintenance free feature during the entire product lifetime.
