Product Description

1.  ZN63 VS1 series 3 phase indoor vcb vacuum circuit breaker 6.6kv 7.2kv 10kv 20kv 24kv


ZN63 series vacuum circuit breaker is three-phase AC 50Hz indoor high voltage switchgear with the voltage of 7.2~15kV, it is used to control and protect electric utilities in industrial and mining enterprises, power stations and substations. Based on more than ten years of extensive experience in design and manufacture of vacuum circuit breaker, we introduce a new generation of high performance product in the twenty-first century.It complies with the requirement of GB1984,DL403 and IEC56 standards and so on.
ZN63A-12/T1250-31.5 vacuum circuit breaker passed the type test in KEMA International Electric Experimental Station in Holland.
2. Main features:
⚫Mechanical and electrical durability During rated current, breaking times can reach to 10000, 20000 During rated
short-circuit current, breaking times can reach to 20, 30 and 50 times.
⚫ The circuit breaker has complete functions. It is used to switch on/off various loads as specified by DL standards, such as method 1-5, capacitor, out-of-phase conditions.
⚫ Easy maintenance Normally, it just needs to clean the operating mechanism and add lubricants.
⚫Vertical insulating tube Protect it from various environmental impacts.
⚫With complete product portfolio Rated current from 630A to 4000A Rated short-circuit current form 20kA to 50kA
⚫ It has the features of series, strong versatility, convenient use and easy maintenance. All products have passed
500 running-in tests according to reliability principle in the factory before delivery, so as to ensure the reliability.
⚫ We will provide you with qualified and high-efficient after-sales service.
