Omni-Rupter® Switches
Mounting Styles
S&C Omni-Rupter Switches are expressly designed for overhead feeder switching and for us in sectionalization schemes. These interrupter switches are available in four mounting configurations to accommodate the variety of line constructions encountered on today’s distribution systems:
Upright Mounting Configuration
Switches in the popular upright mounting configuration are suitable for horizontal distribution-feeder line configurations and they are available with extra mounting pole clearance. Upright Omni-Rupter Switcher use a rotating-type manual operating handle. To guard against animal related outages, upright interrupter switches are also available with optional wildlife protection. Other options include the hookstick operating mechanism and surge arrester mounting brackets. Upright Omni-Rupter switches can be specified with either a steel or fiberglass base.
Vertical Mounting Configuration
Switches in the vertical mounting configuration are ideally suited for use at cable risers and transformer tapoffs from overhead lines. Vertical Omni-Rupter Switcher use a reciprocating-type manual operating handle to open and close the switch-and can be provided with the hookstick operating mechanism. Upright switches are available with optional surge arrester mounting brackets and can be specified with either a steel or fiberglass base.
Tiered-Outboard Mounting Configuration
Switches in the tiered-outboard mounting configuration are designed for vertical (phase-over-phase) distribution-feeder line configurations. Tiered-outboard (Phase-over-phase) Omni-Rupter Switcher use a reciprocating-type manual operating handle to open and close the switch-and can be provided with the hookstick operating mechanism. Tiered-outboard switches are available with optional surge arrester mounting brackets and can be specified with either a steel or fiberglass base.
Triangular Mounting Configuration
Switches in the triangular mounting configuration are tailored for use on systems having pole-top or triangular distribution-feeder line configurations. Triangular Omni-Rupter Switches use a rotating-type manual operating handle to open and close the switch.
All Omni-Rupter Switches are available with a choice of either Cypoxy® or Porcelain insulators and can be supplied with a wide variety of options-including voltage and current sensors, insulated bases, insulated operating rods, surge arrester mounting brackets and wildlife protection. (Switches shown feature steel bases and Cypoxy insulators.)
