Vacuum Circuit Breaker7.2kV~36kV(IEC Std.)/4.76kV~38kV(IEEE Std.)
It provides a product with an integrated
technology, qualified atomic energy and various
voltage ranges.
It is a product incorporated with an accumulatedvacuum technology, operating device design andinsulation design.
It is developed conforming to IEC international standards as well as IEEE (ANSI).
It is a product that can be used at various voltage settings including 7.2kV, 17.5kV, 24/25.8kV, 4.76kV,8.25kV, 12/15kV, 27kV and 36/38kV.
B1-02
It ensures the stability by self-manufacturing the
vacuum interrupters.
We are manufacturing the vacuum interrupters forthe first time in Korea, accumulating the technologieson vacuum and vacuum applications.
We provide the optimal arc extinguishing medium withhigh-vacuum, high arcextinguishing capability.
Based on our product quality and technology, we deliver our goods to many global firms including GE.
The product stability and life is greatly improved
due to the solid insulation by applying molding to
the interruption part.
A core part of the interruption part, VI is molded andsolid-insulated to improve the stability and life ofthe product.
We are fully prepared for the surface discharge of vacuum circuit breaker by enhancing the insulation performance through the solid insulation.
It is easy to perform maintenance and compatible
with new. old products.
It uses the accumulated design data to display outstanding compatibility with old/new products.
It is designed to enable easier maintenance and CB can be inspected by simply checking the contact consumption and control circuits.
A cover made up of an insulation material is adopted to maximize the safety of operators
It reflects the trend of electric equipments by applyingnice design.
Class1E Vacuum Circuit Breaker For Nuclear Power Plant
It completed the seismic test, acquiring GENERIC
Class.
It completed the seismic test based on BroadbandGeneric Spectra of IEEE C37.98 and meets the seismicstandards of all nuclear power plants around the world.
It is well-known throughout the world as it
passed Class1E VCB performance test.
Class 1E VCB for nuclear power plants is anufacturedbased on the nuclear power certification system and ithas completed the development test complying withKEPIC, EED 1100-2005.
Its quality improved greatly with the superior
breaking function.
The breaking time and arc time is shorter than that ofother CBs, and it can be used under unfavorableconditions such as under gas and ion emission withoutany severe impacts on circuit switching, ground fault,high-speed reclosing and condenser bank switching.

The operating and control power of our VCB is DC power in standard but AC powercan also be used depending on the composition of load equipments and conditions.A Capacitor Trip Device can be installed in addition in order to control the VCB evenwhen there is a commercial power failure.
It is a switch to indicate whether a draw-out type VCB that uses a draw-out unit is inthe connecting position or test position in remote and this is installed in the draw-outunit of the VCB.
