The vacuum circuit breaker operates on an advanced protection mechanism. When detecting overload or short-circuit conditions, the integrated current sensor transmits signals to the intelligent controller. This triggers the tripping mechanism which rapidly separates the contacts within the vacuum interrupter, effectively extinguishing the arc and protecting the electrical circuit.

The breaker features a robust construction with multiple key components:
- Operating Mechanism: Precise mechanical device controlling contact movement
- Vacuum Interrupter: Core component containing silver-plated copper contacts within ceramic insulation
- Contact Arm: Movable current-carrying component for reliable connection
- Insulating Cylinder: High-grade insulation housing for safety
- Finger Cluster Contacts: Multi-point contact design ensuring stable conductivity

This industrial-grade circuit protection device is designed for demanding applications in power distribution systems, offering reliable performance and multiple protection functions.
