VSC medium-voltage indoor vacuum circuit breaker is applicable for three-phase AC power
system of rated voltage 7.2kV~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 KYN96, ABB type ZS 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 VSC terminal buffer guarantees the indoor terminal is ever more reliable in nay operation environment. VSC can fully meet the requirement of GB, DL, IEC, DIN, VDE as well as standards of other advanced industrial countries.
