Conso Electrical Science and Technology Co., Ltd. is a medium scale manufacture to produce vacuum circuit breaker, compact substation and distribution transformer. To produce a reliable vacuum circuit breaker, Conso Electrical takes the incoming material of a vacuum circuit breaker seriously, especially for oversea clients. Each of 11kv 630a 11 kv vcb vacuum circuit breaker will run a series tests until reach to the requirement.
11kv 630a 11 kv vcb vacuum circuit breaker is an indoor switchgear of three-phase AC 50Hz power system with rated voltage of 12kV, which is used as the protection and control unit of power grid equipment and power equipment of industrial and mining enterprises. It is suitable for places requiring frequent operation under rated working current, or multiple breaking short-circuit current. The circuit breaker adopts the all-in-one design of the operating mechanism and the circuit breaker body, which can be used as a fixed installation unit or can be equipped with a special propulsion mechanism to form a handcart unit role.

"Cast Pole VCB": The term "cast pole" denotes the utilization of epoxy resin casting to enhance mechanical strength and effective insulation class, to prevent electrical arcing or tracking between the phase to the phase and the phase to the ground.
"Side Mounted VCB": The descriptor "side-mounted" signifies that the interrupter is positioned on the vertical, resulting in a Vacuum Circuit Breaker that is longer yet flatter in dimension. This design caters to the requirements of switchgear configurations, such as SF6 loading breaker panels.
"Insulating Cylinder VCB": The "insulating cylinder" designation points to the shape of insulation material of interrupters. The horizontal installation is commonly employed, aligning with the design of medium voltage electrical panel as the bias of budget-friendly.
