Vacuum Circuit Breaker(VCB)

Introduction of item

Vacuum Circuit Breakers are equipped with high speed, spring-assisted mechanisms assure quick-make, quick-break operating and tripping time shall not exceed 3 cycles. They are designed with several built-in interlocks and safety features.

It is a premium product with a safer, more stable operation based on the user-centered design and its insulation improved with collective barriers and solid insulation by molding the vacuum interrupter. It stably supplied power to all industrial sectors including the power plants, chemical/steel plants and construction facilities. It is a new-conceptual circuit breaker with short arc time and interruption time due to short-circuits and ground failure, which aims for no maintenance.

Product Features

1) It provides a product with an integrated technology, qualified atomic energy and various voltage ranges.
  - It is a product incorporated with an accumulated vacuum technology, operating device design and insulation 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.
2) It ensures the stability by self-manufacturing the vacuum interrupters.
  - We are manufacturing the vacuum interrupters for the first time in Korea, accumulating the technologies on vacuum and vacuum applications.
  - We provide  the optimal arc extinguishing medium with high-vacuum, high arc extinguishing capability.
  - Based on our product quality and technology, we deliver our goods to many global firms including GE.
3) 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 and solid-insulated to improved the stability and life of the product.
  - We are fully prepared for the surface discharge of vacuum circuit breaker by enhancing the insulation performance through the solid insulation.
4) 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 designed to enable easier maintenance and CB can be inspected by simply checking the contact consumption and control circuits.
  - A cover made up of and insulation material is adopted to maximize the safety of operators.
  - It reflects the trend of electric equipments by applying nice design.
