ZN*3(VS1) - *2
 Indoor High Voltage Alternating Current Vacuum Circuit Breaker

1  General

ZN*3 (VS1) - *2 Indoor High Voltage Alternating Current Vacuum Circuit Breaker is a kind of *-phase AC *0Hz high voltage switchgear with rated voltage 7.2kV**2 kV used as a protective and control unit in electric grid, industrial and mineral power equipments.   The circuit breaker complies with relevant requirements specified in China National Standard GB ********3 "High Voltage AC Circuit Breaker", JB / T********8   "3.6kV~*0.5 kV Indoor High Voltage AC Vacuum Circuit Breaker", DL / T**3 - ***0   "Technical Conditions for Ordering *2kV ~ *0.5kV Indoor High Voltage Circuit Breaker" as well as those in IEC ****1 - **0 - ***8 "High Voltage Switchgear and Control gear Part ***0: Alternating Current Circuit Breaker".     In fact, it offers a very reliable interlocking performance.
ZN*3 (VS1) - *2 Indoor High Voltage Alternating Current Vacuum Circuit Breaker works with a spring operating mechanism as a whole.   The circuit breaker may be fixed in cubicle as a fixedly mounted unit or fixed in a pallet as a truck unit (refer to Fig. 1).
