Mass Production of VS1‑12 Indoor Vacuum Circuit Breakers as Core Matching Components for High‑Voltage Switchgears

2026-09-05 15:19:29

Indoor high‑voltage vacuum circuit breakers act as core executive components for complete switchgears. Hongsu VS1‑12 (ZN63A‑12) series indoor high‑voltage vacuum circuit breakers roll off production lines in large volume, compatible with various intermediate‑cabinet models represented by KYN28‑12.

VS1‑12 vacuum circuit breakers adopt high‑performance vacuum interrupters and spring operating mechanisms with stable switching‑on/off actions and long mechanical service life, enabling rapid disconnection under overload and short‑circuit faults. Multiple rated‑current and short‑circuit breaking specifications are available to satisfy diversified power‑supply demands of power grids, factories and commercial buildings.

Hongsu Electric realizes collaborative R&D and manufacturing of circuit‑breaker components and complete cabinets. Integrated testing of components and assemblies avoids compatibility risks caused by multi‑supplier matching and guarantees long‑term stable operation of complete high‑voltage switchgears.
