KCVB1C 7.2 kV/permanent magnetic actuator 12 kV series ac high voltage vacuum circuit breaker is suitable for the 7.2 kV / 10 kV and below the voltage level of the three-phase ac 50 hz in the power system, so as to ensure safe and reliable control and protection of critical load. Can be performed within the rated current is relatively frequent operation, can be repeatedly open circuit rated short circuit current. Through summarizing the company over the years the
use of user experience, and improve the design of products regardless of appearance or performance, reliability and easy to use maintenance have increased greatly. More reliable for capacitive loads for the on and off (transformer and capacitor (AC - 6 a) set the on and off (AC - 6 b)), with the latest technology the permanent magnetic operating mechanism of high voltage vacuum circuit breaker, with reliable operation, good performance, long service life, suitable for frequent movement is known, is replacing the original technology become the market mainstream products, applicable to electric power compensation and filtering, and other areas of the capacitive load, catering to the power network of green and energy saving.

Product features
The main loop of the low
Low vacuum switch tube adopts domestic well-known manufacturers of products. Mature technology, reliable quality, good market reputation.
The whole machine volume is small and exquisite, reasonable structure, easy installation and use, the smallest in the domestic similar products.
Low electromagnetic system
Permanent magnetic actuator with double steady state, break-brake use break-brake spring combined with permanent magnet, the character of break-brake with vacuum switch tube features more matches. Simple control circuit, the circuit breaker is more economic, applicable and easy to use.
Stable and reliable low undervoltage tripping. With integrated manual tripping device, manual brake light is reliable.
Low action structure
Flexible shaft bearing, bearing no binding, axial dynamic small, improve the operation performance and the - sex.
Reasonable action mechanism, to ensure that the vacuum tube moving conductive rod axial alignment. Improve the performance of circuit breaker and reliability. Low contact pressure, strengthen the main contact improves the performance and movement characteristics. The index is better than similar products.
"Easy to use and maintain
Low secondary loop adopts rail mounted terminal, can also according to customer's need to adopt the plug connection, connection is convenient, safe and reliable.
