Vacum Circuit Breakers

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.


With rigid structure and minimized moving parts, HVF breaker operation mechanism features
reduced maintenance requirements providing high reliability and long-life expectancy.
◆ The breakers are more compactly designed in size with high performance vacuum interrupters, which
are made with the special contact material and advanced vacuum technology.
◆ This series are certified by New IEC publication 62271-100, ANSI C37.09 and other domestic standards.


HVG Vacuum circuit-breakers are very compact, so it is possible to reduce the switchgear size and to minimize its insulation space.
◆ This type of circuit breaker has a compact structure, which can be easily maintained, so it requires minimal maintenance.
