What is a Vacuum Circuit Breaker?
A Vacuum Circuit Breaker is a switching device that uses a vacuum interrupter to extinguish arcs during current interruption in medium-voltage power systems.
How does a Vacuum Circuit Breaker interrupt fault current?
Vacuum Circuit Breaker operation separates contacts inside a vacuum chamber, where the absence of ionized gas enables rapid arc extinction and current interruption.
Which applications use a Vacuum Circuit Breaker?
Vacuum Circuit Breaker units are used in substations, industrial plants, and distribution networks operating up to 40.5 kV.
How is the rated short-circuit capacity selected?
Rated short-circuit capacity is chosen based on system fault level calculations, matching the 21 kA or 31.5 kA breaking ratings to network requirements.
What control power is required for a Vacuum Circuit Breaker?
Vacuum Circuit Breaker mechanisms operate with AC/DC 220 V control voltage, compatible with standard protection and control systems.
