VS1 indoor high voltage vacuum circuit breaker – Handcart Type for Smart, Safe Power Distribution

Engineered for demanding medium-voltage environments, the VS1 indoor High Voltage vacuum circuit breaker in handcart configuration offers a perfect blend of safety, serviceability, and performance. Designed primarily for 12kV systems, this withdrawable unit is widely deployed in industrial plants, commercial complexes, utility substations, and infrastructure projects where rapid maintenance and operational continuity are critical.

Unlike fixed breakers, the handcart type vacuum circuit breaker enables tool-free insertion and extraction from its switchgear compartment—dramatically reducing downtime during inspections or replacements. Its robust mechanical interlocks prevent accidental operation, while the clearly marked open/close indicators enhance on-site safety and user confidence.

Built with a hermetically sealed vacuum interrupter and a spring-driven mechanism, the VS1 indoor high voltage vacuum circuit breaker delivers reliable interruption of fault currents up to 31.5kA and supports continuous load currents from 630A to 4000A. It complies with IEC 62271-100 standards and integrates seamlessly into standard KYN28 and similar metal-clad switchgear cabinets.

The unit’s compact footprint and modular design make it ideal for space-constrained installations, while optional auxiliary contacts and smart monitoring interfaces support integration into SCADA or IoT-based power management systems. The durable enclosure—visible in the image above—features a corrosion-resistant finish suitable for long-term indoor use under varying environmental conditions.

Whether modernizing aging infrastructure or building next-generation switchgear, the handcart type vacuum circuit breaker provides a future-proof, low-maintenance solution that enhances grid reliability and reduces total cost of ownership across the asset lifecycle.
