General
ZN63A – 12 (VS1) Indoor AC Medium Voltage Vacuum Cir-
cuit Breaker is suitably applied in AC three phase 50Hz, 10kV
power systems for switching over loads in different nature in fre-
quent operation situations. It is generally used in industrial and
mineral enterprises, power plants and substations for protection
and control of their electrical apparatus.
It can be mounted both in various central-located truck type
switchgears such as KYN28 – 12 (GZS1) and in fixed type
switchgears such as XGN -
This product is manufactured in compliance with China
National Standard GB1984 “AC High Voltage Circuit Breaker”,
China Ministerial Standard JB3855 “3.6 – 40.5 kV Indoor AC High
Voltage Vacuum Circuit Breaker” and International Electric Engi-
neering Commission Standard IEC “High Voltage AC Circuit
Breaker” as well as DL/T403 “Ordering Conditions on 12 – 40.5
kV Indoor AC High Voltage Vacuum Circuit Breakers”.

Structure features
* Forward and backward configuration of interrupter
and operating mechanism with drive link to ensure
the general coordination performance of the circuit
breaker as a whole.
* Sealed ceramic and porcelain vacuum interrupter, Cu-
Cr contact material and longitudinal magnetic field
2are worldwide recognized as the most advanced arc
extinguishing strategy.
* The vacuum interrupter mounted in an insulating col
umn formed by APG, a new processing technology,
not only reduces the whole dimension of the circuit
breaker, but also prevents of the interrupter from in
jury and surface pollution by foreign objects.
* On basis of advantage of similar foreign products,
the insulating column with internal shed and re-en
forcement ribbon greatly boosts the capacity of peak
value withstand current in terms of insulating level.
* Spring operating mechanism with both motor-driven
and manual-operated modes. When the circuit
breaker is in operation, the energy of the energy charg
ing spring transmits to the pull rod assembly via an
output cam, and then from the pull rod to the mov
able contact.
* The advanced and reasonable damping device makes
no bounce in opening operation and attenuates open
ing impulse and shock.
