Description

VS1-12 (ZN63A) Indoor High-voltage Vacuum Circuit Breaker

VS1-12 (ZN63A) indoor high-voltage vacuum circuit breaker adopts closed insulating form and installs inside and outside pleat on the main insulating cylinder. Its comparative creeping distance reaches the standard of DL. The excellent characters of the circuit breaker are as follows: small size, reliable insulation, no pollution, anti-explosive, stable performance, precise technical parameters, long maintenance cycle and so on.

VS1-12 (ZN63A)indoor high-voltage vacuum circuit breaker is a fixed type circuit breaker developed and designed on the basis of handcart type VS1. It can match with the cabinets such as XGN2, GG1A and GGX2 and replace the disqualified old breaker (eg. oil circuit breaker). The circuit breaker owns many merits, such as few changes, low investment, easy installation and saving time.
