Rotary Switches

The ABB LBOR-II switch is a manually operated, two position, load make or break, oil immersed, rotary switch. It is designed for use with distribution transformers (pad-mounted or submersible) and self contained distribution switchgear. With a smaller mounting envelope than most switches on the market today, the LBOR-II switch has been designed to save you money. The reduced envelope allows for smaller equipment that requires less oil and steel to manufacture.

ABB LBOR II switches feature a wide range of configurations with voltages through 38kV and current through 400 A.  Switches can be either nut-mounted or welded.  Installed with a retained gasket and a single mounting nut, the LBOR-II switch with the nut mounting system allows for quick mounting in both OEM and replacement installations.  Installed with an ‘A’ frame mounting bracket, the weld-in mounting system is a time proven method for secure installation of the LBOR-II switch.  The weld-in system provides a stout, reliable system for mounting and sealing the LBOR-II switch.  Click on the Support and Documentation tab above to download the product brochure to see all available options.
