Load Break Switches (LBS)

We manufacture Load Break Switches (LBS) in three pole, manual / motorised operated upto 33KV range. Our LBS is simple but robust design with trouble free mechanism. These are used in application like transformer switching, ring main gears (RMG), condensers, etc.

We offer LBS that can be make / break the normal rated current and make the short circuit current. The design of Load Break Switch is user friendly and easy in operation reliable function. Load Break Switches are manufactured in accordance with IS 9920 / IEC 265.

Salient Features

  • Available in both Indoor / Outdoor version and Extensible
  • Metal clad hence no access to live parts
  • No arc chute hence minimal maintenance
  • Maintenance free mechanism
  • Separate HT / LT Compartments
  • Compact design with aesthetic look
