Vacuum Circuit Breaker vs SF6 Circuit Breaker
In the world of medium and high-voltage power systems, choosing the right circuit breaker is critical for operational safety, efficiency, and long-term reliability. Two of the most commonly compared technologies are Vacuum Circuit Breakers (VCB) and SF6 Circuit Breakers. Though both serve the same fundamental purpose—interrupting current flow to protect electrical systems—they differ significantly in design, application, and performance characteristics.
This article explores the key differences between VCB and SF6 circuit breakers, helping engineers, procurement teams, and facility managers make informed decisions.
