Vacuum Circuit Breakers (VCBs) are a critical component in electrical networks, playing a vital role in medium voltage (above 1 kV) applications. They function as switching devices, interrupting short-circuit currents and enabling operational switching (on-off operations) of individual circuits or electrical equipment. Their core functionality lies in quenching the electric arc that forms when contacts open in a vacuum environment. VCBs are widely favored due to their reliability, extended durability, and minimal maintenance requirements.
