These vacuum circuit breakers are designed for three phase AC 50Hz power system with rated voltages of 12, used as protection and control unit for grid equipment and power equipment of industry and mining enterprises. They are suitable for areas where frequent operations of rated operating current or multiple switching of short circuit current are required. The operating mechanism is integrated into the circuit breaker body. The circuit breaker can be installed as a fixed unit, or equipped with a truck or a withdrawable part to easily move into the switchgear.
