Vacuum Circuit Breakers Explained: Why Degatech Electric is Your Ideal MV Supplier

Posted 2025-10-11 07:19:53

In any medium voltage electrical network — whether in an industrial plant, a utility substation, or a renewable energy facility — one component stands out for its protective importance: the vacuum circuit breaker (VCB).

A vacuum circuit breaker is a type of electrical switching device specifically designed to interrupt fault currents and disconnect loads safely and rapidly. It operates by extinguishing electrical arcs within a vacuum-sealed chamber, which has one of the highest dielectric strengths available. This makes VCBs exceptionally reliable, durable, and safe compared to alternatives like oil or air breakers.

Key Advantages of Vacuum Circuit Breakers:

🔌 Fast Arc Interruption: The vacuum environment allows for almost instantaneous arc quenching, minimizing damage to equipment.
🛡️ High Durability: Since there’s no contact erosion from arcing in the air, VCBs tend to have longer operational lifespans.
🧼 Clean Operation: No oils or greenhouse gases are involved, making them environmentally friendly.
🏭 Compact & Lightweight: Especially useful in modern, space-constrained switchgear assemblies.

These qualities make vacuum circuit breakers the go-to solution for medium voltage switchgear systems (1kV – 36kV) around the world.
