Product Detail

SM6 Series Medium-voltage Switchgear

SM6 is an extensive module combined metal sealing medium voltage switchgear, the selected switches include:

? Load switches

?Fluarc SF1, SFset or Evolis circiut breakers

? Rollarc 400 or 400D contactors

? Disconnection switches

SM6 switchgears can be used in secondary substation below 24KV in industrial and mining enterprises. In addition, SM6 can ensure the safety of people and equipment and it is very easy to install and operate.

SM6 series products can be used in MV/LV substations and industrial and mining power distribution stations;
