HYUNDAI
HVG Vacuum Circuit Breaker
(VCB)
Ensuring excellent
switching capability and high quality with various advantages
|
- Retaining the high dielectric strength
with the interrupter of the high vacuum degree of 10-7mbar.
- Providing reliable mechanical
performance and long-life expectancy with rigid structure of motor-spring
energy stored mechanism.
- Having excellent breaking capability
with the special contact material designed by the advanced vacuum technology.
- Having rapid breaking time of 3 cycle.
- Certified by New IEC publication
62271-100 and other related standards by HYUNDAI in ISO9001/14001 and
OHSAS18001 certified facilities.
