Product Description

VB4 medium-voltage indoor vacuum circuit breaker is applicable for three-phase AC power
system of rated voltage up to 12~24kV 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 KYN28 or AMS, ABB type ZS1 series, etc. This circuit breaker is
standards as GB1984-2003 AC high voltage circuit breaker,JB3855 3.6-40.5Kv indoor AC
High voltage circuit breaker,DL/T403 Specification of 12-40.5Kv indoor High voltage vacuum
circuit breaker for order as well as IEC60694.
This circuit breaker is made with mature APG technology. The application of VB4 terminal
buffer guarantees the indoor terminal is ever more reliable in nay operation environment. VB4
can fully meet the requirement of GB, DL, IEC, DIN, VDE as well as standards of other
advanced industrial countries.

Main technical
Advanced technics and capabilitiesThe 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.
