SF6 free in withdrawable design for secondary distribution
The switchgear M20 is a compact switchgear for the application in different areas of the secondary distribution in utilities and industry.
With its very compact design, achieved by moving the circuit breaker vertically in the panel, it is a real alternative to SF6-insulated switchgear.



  • Compact secondary distribution switchgear with withdrawable circuit breaker.
  • SF6-free, air insulated.
  • Efficient use of space thanks to very compact design.
  • Type-tested pressure relief duct.
  • Easy upgrade of disconnector panels with motor drive for a later remote control.
