12kV Load Break Switches(LBS)

12kV indoor/Outdoor Load Break Switch with epoxy support Insulators, double switch blades and contact with arc quenching chambers, with spring charging mechanism for three-pole disconnection, HT HRC fuse trip & Earth switch with mechanical interlock facility.

The LBFS manufactured by us are suitable for both Indoor & Outdoor applications, for switching of Transformers, Condensers, Cables etc. Our LBFS is approved by MSPWD & MSEDCL to be used in various Industries, Commercial complexes, residential apartments etc


Safety & Interlocks:


  • Mechanical interlocks are provided between main switch & earth switch in such a way that the earth switch can be closed only when the main switch (LBS) is OFF & vice versa.
  • Access to the HT HRC fuses is not possible when the main switch (LBS) is in ON condition.
  • All the live parts are on Rear side hence more safety to the operator.
