ZN63S-12 (VSI+) Indoor
High Voltage AC Vacuum Circuit Breaker
General
ZN63S-12 (VSI+) indoor high voltage AC vacuum circuit breaker is a kind of
indoor high voltage switchgear of 3-phase AC, 50 Hz, with rated voltage of
7.2-12kV. It is used as protection and control element in electric wire netting
equipment, power equipment of industrial and mineral enterprises.
The breaker conforms to the national standards of GB1984-89 "AC High Voltage
Circuit Breaker", JB3855-96 "3.6~40.5Kv Indoor High Voltage AC Vacuum
Circuit Breaker", DL403-91 "Technical Conditions for Ordering 10-35kV Indoor
High Voltage Vacuum Circuit Breaker" and as well as the relative IEC standards.
ZN63S-12 (VSI+) indoor high voltage AC vacuum circuit breaker can operate
frequently with ability of multi-breaking and quick on-switching. It has reliable
interlocking function.
ZN63S-12 (VSI+) indoor high voltage AC vacuum circuit breaker adopts the
design of integrating the operating mechanism with the breaker, available for
serving as permanently installed unit, or as hand-trolley unit after equipped with
underframe.
