1 ZN39G-40.5 Series ZN39G-40.5 indoor high voltage vacuum circuit breaker (VCB)
50HZ GB1984 is a high voltage electric device with three phases, AC, 50Hz. VCB complies
the standard GB1984, JB3855, etc. VCB suit for 35KV electric distribution
JB3855
system of industry, mine, power plant, steel factory, transformer, and so
35KV
forth to control and protection. And specially suit for very high frequency
workplace such as electric arc furnace, transformer, open / close
capacitors group.
2
With optimize designing, the VCB s CT, CD spring operating
CT CD 3AF
mechanism is replaced by 3AF spring operating mechanism of SIEMENS,
that make the VCB and operating mechanism as a combine. The structure
simplifies the transfer tache, improves THE VCB s performance and
3
reliability, The VCB s durability up to 30 thousand. After the VCB adopts
6
permanence magnetic operating mechanism that its durability up to 60
thousand.
3 GBC- VCB has reliable interlock, is widely matching with tanks such as
40.5 XGN-40.5 JYN1-40.5 GBC-40.5 XGN-40.5 JYN1-40.5.

4 GBC-40.5 XGN-40.5 JYN1-40.5
Introduce for excellence performance
1. Absorbing the siemens technology, adopting ZN12(3AF) spring operating mechanism, combine the
mechanism with circuit breaker, which increases the performance of reliable.
2. Mechanism durability is up to 30 thousand without faults.
3. Equipping the permanence magnetic operating mechanism, It is not need to maintenance in 60
thousand times mechanism durability , it is first choice for electric steel furnace.
4. It also can match with many series tanks such as GBC-40.5, XGN-40.5, JYN1-40.5 .
