Vacuum circuit breakers are critical components in modern electrical distribution systems, utilizing high vacuum as the arc-quenching medium. These devices offer superior insulation properties and rapid arc extinction capabilities when interrupting current flow.
The breaker's construction features fixed and moving contacts made from highly conductive, erosion-resistant materials capable of withstanding high-temperature arcs. This robust design ensures reliable operation and extended service life with minimal maintenance requirements.
These breakers find extensive application in power distribution networks including substations and industrial power grids. Their fast operation and dependable performance provide effective protection against short-circuits and over-current conditions, safeguarding valuable electrical equipment.
Key advantages include high breaking capacity, excellent dielectric recovery strength, and compact design. The vacuum interruption technology eliminates the need for external arc-quenching media, making these breakers environmentally friendly and maintenance-free compared to other types.
Available in various voltage ratings and current capacities, our vacuum circuit breakers can be customized to meet specific application requirements. The standardized design ensures compatibility with existing switchgear while delivering superior performance characteristics.
