WHAT IS ASUBSTATIONS VACUUM CIRCUIT BREAKER MODULE
The VX type of circuit breaker series is designed for all standard applications in the medium voltage range. The compact VX type vacuum circuit breakers can be easily integrated not only into all types of switchgears, but also retrofitted into existing switchgears. They are produced for long life time operation and switching under short circuit conditions. VX circuit breakers can be installed in all type of air insulated medium voltage switchgear assemblies. The compact design, especially the small depth and width, are the key advantages of the product. The VX type of circuit breaker frame is made of premium class "marine" grade stainless steel to avoid corrosion and related problems

- Fits into all air insulated medium voltage switchgear from 6 kV to 24 kV
- Suitable for short circuit breaking currents up to 40 kA and rated currents up to 3150 A
- Low planning costs due to multiple switchgear panel versions
- Same dimensions and connection dimensions across several voltage levels
- Optimal system integration, also for retrofitting, thanks to a large selection of pole-center distances, widths across flats and comprehensive installation accessories
- Fixed-mounted design and withdrawable design
- High availability thanks to 20,000 maintenance-free operating cycles
- Optionally up to 30,000 operating cycles
