Hybrid Switchgear PASS M00 for offshore wind farms – 72.5 kV

Compact modules which can be installed or removed via narrow openings like wind tower hatches

PASS M00 for offshore wind farms belongs to Hitachi Energy's innovative high-voltage hybrid switchgear family PASS (Plug and Switch System). PASS encloses all functions of a complete switchgear bay in a single module. PASS M00 for offshore wind farms is a further step ahead in the combination of compactness and function integration typical of PASS modules, as it can be inserted and fitted in narrow spaces such as a wind tower or nacelle. The cable ending, the disconnecting switch and the earthing switch are now enclosed in a single assembly including:

  • Circuit breaker
  • Combined disconnector and earthing switches
  • Voltage transformers and Voltage sensors
  • Current Transformers
  • Motor drive option
  • Fast earthing switch option

The PASS module is completely factory assembled and tested, ready for rapid installation and energization.


  • Line and transformer switching
  • Offshore wind farms application
  • Extreme climates and high altitude application

Why Hitachi Energy?

  • PASS is the most widely installed hybrid switchgear worldwide, protecting networks in many different climates and applications.
  • Close to GIS compactness at AIS value - the best of both worlds
  • Delivered fully assembled and tested, energizing in 12 hours on-site
  • Modular design enables highly customizable solutions in a short manufacturing time
  • Global service organization, local everywhere
