MEDIUM VOLTAGE VACUUM TECHNOLOGY

Siemens Vacuum Technology

Discover a comprehensive portfolio of vacuum switching technology for installation in airinsulated medium-voltage switchgear, enabling sustainable and reliable power distribution. Our proven and maintenance-free technology is based on vacuum interrupters and comply with all international standards.

EFFICIENT POWER SUPPLY

High availability and dependability

Ensure reliable protection and switching operations in almost all power distribution and industrial network applications, even under difficult environmental conditions with:

  • Vacuum circuit-breakers SION for standard applications:
    The compact design and modularity enable a small footprint for optimal integration in all MV switchgears, for primary and secondary distribution.
  • Vacuum circuit-breakers for special applications:
    The flexible design meets customer-specific requirements, including withstanding huge loads for e.g. generators and rail operations.
  • Vacuum contactors:
    For safe switch operating currents and end-to-end protection of your medium voltage systems
  • SIQuench:
    For arc fault detection
