Advanced technics and capabilities

The circuit-breaker VB4P-12(24) is the newest equipment in the voltage class of 12kV up to 24kV manufactured by Zhejiang Farady Electric Co., Ltd. It is universal used in power distributing and transforming systems of power stations, power generators, and secondary substations of mines, industries and infrastructures.

The circuit-breaker VB4P-12(24) has complete type specifications:
the rated voltage is 12kV, the rated current is up to 4000A and the rated short circuit breaking current is up to 50kA.

The circuit-breaker VB4P-12(24) is equipped with modularized spring operating mechanism which has characteristic of more convenient maintenance, rapider replacing of parts and more reliable performance.

The circuit-breaker VB4P-12(24) adopts embedded poles that the vacuum interrupter with low resistance and the primary main electrical circuit are cast in insulating cylinders by epoxy resin.

This structure makes the breaker have more reliable insulation.
The embedded poles of circuit-breaker VB4P-12(24) have the technique of ventilation and convection. Besides, the vacuum interrupter is with low resistance. All of these reduce the power consumption and the temperature rising due to the longtime running of circuit-breaker.
The circuit-breaker VB4P-12(24) has perfect performance when it is breaking short-circuit current or being operated frequently.


Beside that it also has the functions of automatic reclosing and reliable operating.  
The driving mechanisms of circuit-breaker VB4P-12(24) are designed by professionals in CooperNature and with characteristic of reliable closing performance, low impact force and longer lifetime. The mechanical lifetime can be up to 30000 cycles.

All of the mechanism's surface of circuit-breaker VB4P-12(24) is disposed with special process and lubricative technique. Not only the rust-resistance capability is improved but also the operating performance is ensured. The circuit-breaker is also applicable to humid and hot regions.

The circuit-breaker VB4P-12(24) has been through the whole type test in accordance with the standards of GB and IEC.
