HVF1-12P series indoor 10kV vacuum circuit breaker, the three-phase AC 50Hz, rated voltage 12kV and below the indoor high voltage distribution device. It is compatible with KYN28-12(Z)(GZS1) type switchgear, and can also be compatible with various types of switchgear. It is suitable for the control and protection of power plants, substations and other transmission and distribution systems, and can also be used in places with frequent operations. The products meet the requirements of GB1984 "AC high voltage circuit breaker".

Supporting products are: isolation car and fuse car, etc.

The circuit breaker adopts composite insulation mode, which meets the insulation requirements under normal operating conditions, and effectively reduces the volume of the circuit breaker, and the overall layout is reasonable, beautiful and simple.

The operating mechanism adopts a spring mechanism integrated with the circuit breaker body, which can be operated by AC or DC or manually. The circuit breaker is divided into fixed type and manual type, of which the manual type is equipped with a special propulsion mechanism, which can easily move the manual in the switch cabinet, and the mandatory mechanical locking mode is equipped to meet the functional requirements of the switch cabinet "five defenses".

Wide range of application, can be installed in the fixed switchgear, can also be used for mobile switchgear.
