S&C Alduti-Rupter® SwitchesOutdoor Distribution (14.4 kV through 69 kV)The Standard Mounting Arrangementsfor S&C Alduti-Rupter SwitchesThree-pole S&C Alduti-Rupter Switches for outdoordistribution are offered in an unequalled variety ofStandard Mounting Arrangements—a selection ofarrangements that cuts your engineering costs as wellas lead time.Note: Vertical-Break Integer, Side-Break Integer, andDouble-Break Integer Alduti-Rupter Switches, unlikeother styles of Three-Pole Alduti-Rupter Switches,consist of three switch poles factory-assembled on asingle base. Integer Styles are offered in a variety ofbasic mounting arrangements illustrated on pages 4,8, 9, 16, and 17. Certain statements in this documentdo not apply to the Integer Styles; such statements areindicated by footnote “l”.The selector charts that follow illustrate 96 StandardMounting Arrangements, classified by:••Style of switch—Side-Break Integer, Side-Break,Vertical-Break Integer, Vertical-Break, Double-Break, and Double-Break Integer.••Type of mounting—single-pole, two-pole, structure,or pedestal.••Type of operating mechanism—rotating orreciprocating.Many advantages accrue from using one of theStandard Mounting Arrangements:No Problem with Last-Minute ChangesIn the event of a last-minute change, you can choose anew arrangement from the selector charts, and locatethe erection drawing for the desired arrangement onsandc.com. By comparing the bills of material on theEDs, you can determine if additional or different partswill be required.Erection Drawings Immediately AvailableEach Standard Mounting Arrangement in the selectorcharts is identified with an ED number; this numberindicates the erection drawing corresponding to themounting arrangement. EDs are printed in legible,double-page, “D” Size format folded to “A” size forconvenient filing. They are available at no charge in asmany copies as required; just ask the local S&C SalesOffice for the ED numbers needed.Each erection drawing is complete with detailedinstallation data, including an outline drawing ofthe mounting arrangement, base details, operatingmechanismcomponent details, a bill of materials,installation notes and illustrations, and recommendedclearances.No Design Delays; No Ordering DelaysSwitches can be ordered immediately, and you cancomplete your line or station layout, plus actualdesign work, from erection drawings (EDs) that areimmediately available. No other drawings are requiredfrom S&C to adapt the switches to the majority ofapplications.Reduced Shipping TimeShipping time is greatly reduced because there is nodelay for custom engineering, customer approval, ortime-consuming fabrication of special parts.Typical erection drawing, reduced from full “D” Size.Stocking Switches for Immediate UseStandard Mounting Arrangements make it possiblefor you to buy and warehouse a quantity of Alduti-Rupter Switches with operating mechanisms for yourpreferred arrangements, for use in future installations.You can withdraw a switch from stock at any time andinstall it, without delay.April 01, 2013© S&C Electric Company.Data Bulletin 761-80

S&C Alduti-Rupter ® SwitchesStandard Mounting ArrangementsWhen a Standard Mounting Arrangement is specified,the shipment will include:••Three switch poles or, in the case of an Integer StyleAlduti-Rupter, a three-pole switch, complete withinterphase drive, factory-assembled on a single base.••Mounting pedestal, if ordered (Vertical-Break andDouble-Break Integer Style Alduti-Rupters forPedestal Mounting only).••The appropriate number of sections of verticaloperating pipe and interphase pipe. Refer to thetable below for vertical operating pipe included witheach Standard Mounting Arrangement.••The appropriate set of operating-mechanismcomponents; e.g., handle, rod guides, couplings, bellcrank assembly, etc.••The appropriate detailed erection drawing.••Complete installation instructions.What About Specials?Departures from Standard Mounting Arrangementsare easily handled.
