JG🎥 One Device – Three Functions | 12kV / 24kV Three-Position Vacuum Circuit Breaker
This video demonstrates the operation of our three-position vacuum circuit breaker, designed for modern SF₆-free medium voltage switchgear.
The device integrates three essential functions in one compact unit:
✔ Disconnector
✔ Vacuum Circuit Breaker
✔ Earthing Switch
This integrated architecture helps simplify switchgear design and reduce mechanical complexity.
Key technical parameters
• Rated voltage: 12kV / 24kV
• Rated current: 630A / 1250A
• Short-circuit breaking current: up to 25kA / 31.5kA
• Standard: IEC 62271-100
Typical applications
• Medium voltage switchgear (AIS)
• Ring Main Units (RMU)
• Compact transformer substations
These solutions are particularly suitable for SF₆-free medium voltage switchgear design and modern power distribution networks.
Technical information and drawings are available upon request.
