200A switches with current limiting fuses (Fused BURDs)

G&W Circular Tank Style BURD switches can be equipped with dry well fuse canisters that accept general purpose current limiting fuses to provide overcurrent and fault protection.  The switches also feature load break switching capability in a totally sealed, submersible, dead front device. The switches are designed for use on 1, 2, or 3-phase systems with voltages up to 27kV, 160A load break and continuous current, and 20kA asymmetrical momentary and close into fault ratings.  The switches are designed for installation in small circular vaults with switch operators and high voltage connections on top of the tank. 

The switches are designed to IEEE C37.72 and C37.74 for load break capability. 

  • The switch and dry well fuse canisters are completely submersible
  • Available in 1, 2, and 3-phase designs
  • Ideal for installations in small vaults
  • Switches include dry well fuse canisters which can accommodate many general purpose current limiting fuses.
  • Designs with 1 fuse canister per phase or 2 fuse canisters per phase (Parallel Fuse Canisters) are available. Parallel fuse canisters allow a higher continuous current to pass through the switch before the fuse operates.
  • The Fused Switch Information Sheets in the Resources Box provide valuable information on G&W switches equipped with dry well fuse canisters.
