Vs1-12kV Indoor vacuum circuit breaker with Auto Recloser & Withdrawable Design

Engineered for modern power distribution networks, the Vs1-12kV indoor vacuum circuit breaker combines high reliability, intelligent functionality, and user-friendly maintenance in a compact, withdrawable form factor. This advanced medium-voltage switchgear solution is ideal for industrial facilities, commercial complexes, utility substations, and renewable energy installations requiring dependable protection and rapid service restoration.

Equipped with an integrated auto recloser function, this breaker automatically restores power after transient faults—minimizing downtime and improving grid resilience without manual intervention. The withdrawable vacuum switch design allows for quick isolation, inspection, and replacement, significantly reducing maintenance time and enhancing operational safety in live environments.

The Vs1-12kV indoor vacuum circuit breaker features a sealed-for-life vacuum interrupter, spring-charged operating mechanism, and robust mechanical interlocks compliant with IEC 62271 standards. With rated currents from 630A to 4000A and short-circuit breaking capacities up to 31.5kA, it delivers exceptional performance under demanding load conditions while maintaining low lifecycle costs.

Its sleek, modular housing—shown in the image above—is designed for seamless integration into standard 12kV metal-clad switchgear (e.g., KYN28 cabinets). Optional smart monitoring interfaces support remote diagnostics, predictive maintenance, and SCADA connectivity, making it a future-ready choice for digital substations.

Whether you're upgrading legacy infrastructure or building a new smart grid system, this versatile indoor vacuum breaker offers unmatched flexibility, safety, and automation—ensuring continuous, efficient power delivery where it matters most.
