Technical data
Indoor High Voltage Vacuum 17.5kv/630A Circuit Breaker
Advanced technique

The circuit-breaker VB4-12is the newest equipment in the voltage class of 36kV manufactured by Wenzhou 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 VB4-12has complete type specifications:
the rated voltage is 12V, the rated current is up to 2500A and the rated short circuit breaking current is up to 31.5kA.
The circuit-breaker VB4-12is equipped with modularized spring operating mechanism which has characteristic of more convenient maintenance, rapider replacing of parts and more reliable performance.
The circuit-breaker VB4-12 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 VB4-12have 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 VB4-12has perfect performance when it is breaking short-circuit current or being operated requently.
Beside that it also has the functions of automatic reclosing and reliable operating.
The driving mechanisms of circuit-breaker VB4-12 are designed by professionals in Faradyand 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 VB4-12 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 VB4-12has been through the whole type test in accordance with the standards of GB and IEC.
