11kv Vcb Electrical Vacuum Ckt Breaker

The 11kv vcb electrical vacuum ckt breaker is designed for use in 12kV power systems as a protection and control device for power grid equipment as well as industrial and mining power facilities. It can be installed in switchgear such as the KYN28, HXGN, and GG-1A series electrical panel, and it is suitable for applications requiring frequent operations.

Available installation types of the 11kv vcb electrical vacuum ckt breaker include trolley type (handcart), stationary type, side mounted type, and permanent magnet type. According to insulation structure, it is offered in standard type, insulated cylinder type, and cast resin pole type. Compatible auxiliary units of 11kv vcb electrical vacuum ckt breaker include isolation truck, fuse trolley truck, and voltage transformer trolley truck.

The main feature can be show as the below:

Structure: The vacuum interrupter and main conductive circuit are encapsulated in epoxy resin, providing excellent resistance to vibration, dust, moisture, and pollution. This design significantly enhances reliability and extends service life in harsh environments.

Vacuum Interrupter: Delivers strong arc-quenching performance and interruption capability, ensuring high short-circuit breaking capacity (up to 40kA) and stable electrical endurance.

Operating Mechanism: Designed as an integrated unit with the circuit breaker body, it can be flexibly configured for fixed, trolley (handcart), or side mounted installation, to meet the requirements of different switchgear systems.

Protection Functions: Integrated protection against overload, short circuit, and undervoltage, ensuring safe and reliable operation of the power system.

Mechanical Endurance: more than 10,000 operations.
