VS1-12 Vacuum Circuit Breaker (VCB) – Compact Design 2500A 50kA

The VS1-12 vacuum circuit breaker with 2500A rated current and 50kA breaking capacity adopts an optimized compact structural design. The phase-to-phase distance is reduced to only 210mm, compared with the conventional 275mm design widely used in traditional vacuum circuit breakers.

This compact structure significantly improves space utilization inside the switchgear panel, making it especially suitable for KYN28 metal-clad switchgear systems where both high current performance and compact layout are required.
