VB85 high-voltage indoor vacuum circuit breaker is applicable for three-phase AC power
system of rated voltage up to 36kV and frequency 50/60HZ,widely used in many fields such as
power plant, transformer substation, petrol chemical industry, metallurgy, manufacturing
industry, airport, residential area, etc., to control and protect the electric equipment, especially,
It is used for the occasion that needs infrequent operation at rated current or multi-breaking
short circuit current, may be mounted in the indoor air insulating switchgear like type KYN61 or
AMS, ABB type ZS3.2 series, etc.
This circuit breaker is made with mature APG technology. The application of VB85 terminal
buffer guarantees the indoor terminal is ever more reliable in nay operation environment. VB85
can fully meet the requirement of GB, DL, IEC, DIN, VDE as well as standards of other
advanced industrial countries.

Technical data
Advanced techniques and capabilities
The circuit-breaker VB85-36 is 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 VB85-36 has complete type specifications:
the rated voltage is 36kV, the rated current is up to 2500A and the rated short circuit breaking
current is up to 31.5kA.
The circuit-breaker VB85-36 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 VB85-36 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 VB85-36 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 VB85-36 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 VB85-36 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 VB85-36 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 VB85-36 has been through the whole type test in accordance with the
standards of GB and IEC.
