Application
The primary purpose of any cutout is to provide protection tothe lines of your system and the various apparatus on thoselines such as transformers and capacitor banks. Chance TypeC cutouts provide reliable protection from low-level overloadsthat just melt the fuse link, intermediate faults, and very highfaults, through maximum interrupt capacity.
In addition, Type C cutouts can also be used as a sectionalizingdevice. With the use of a portable loadbreak tool, Type C cutoutscan function much like an overhead disconnect switch. A 300amp disconnect blade is also available for this purpose.
Ratings/Specifications
STANDARD Type C cutouts have maximum design voltage rat-ings to simplify the confusing ratings of cutouts. There are norestrictions on application to grounded wye, ungrounded wye,or delta systems having maximum operating voltages (line-to-line) equal to or less than the cutout maximum design voltagerating. (See the LINKBREAK and LOADBREAK cutouts fortheir specifications.) Interruption tests have been performedat full system line-to-line voltage. In each voltage class, thereare continuous current ratings of 100 amps, 200 amps and 300amps. See the table on page 6 for other specifications.

Insulators
The insulators used on Type C cutouts are a sky-glaze grayThe metal to metal leakage distance on the 15 kV cutoutinsulator is 8.7 inches (220 mm), 12.6 inches (320 mm) onthe 27 kV [125 kV LIW (BIL)], 17.3 inches (440 mm) on the27 kV [150 kV LIW (BIL)], 26 inches (660 mm) on the 36kV [170 kV LIW (BIL)], and 28.4 inches (720 mm) on the 36kV [170 kV LIW (BIL)].
Fuseholders
The solid cap on the single vent fuseholder is a copper alloysilver-plated to provide efficient current transfer. An integraring is provided in the top tube casting for opening and closing the fuseholder with conventional disconnect tools fromthe ground, from a bucket truck or from the pole.
The toggle type trunnion casting is a selective silverplated bronze for efficient current transfer to the lowerhinge contacts. A cam shaped projection on each side of thetrunnion casting provides high pressure parallel currentpaths to the lower contacts. These projections, or pivot pinsare cast full round for smooth rotational operation in thehinge. The link ejector assists in arc interruption duringlow fault current or excessive overload conditions. A groovein the center of the link ejector allows the fuse link’s pigtaito go directly from the fuse tube to the attachment nut. Acurved ejector minimizes bending stresses in the pigtail toprevent broken strands. A stainless steel torsion spring onthe link ejector helps to rapidly eject the link from the boreof the fuseholder during interruption. The 200 amp linkejector has a wider groove area and increased spring force
to accommodate the larger links.
The link ejector is pinned to the trunnion casting with astainless steel pin to provide resistance to corrosive elementsand provide smooth pivotal action. An interlocking featurebetween the link ejector and tube casting prevents excessivetension on the fuse link during closure, thereby preventinglink breakage.
The link ejector employs a hammer effect to enhance toggleaction of the trunnion during low fault and overload interruptions, hence dropout action is enhanced. The link ejectorprovides sufficient surface area to facilitate re-fusing bylinemen wearing gloves.
Quality Construction
Efficient Current Transfer
The Chance Type C cutout has an all copper current path. Allcontacts are silver-plated. Terminals are tin-plated bronzefor use with copper or aluminum conductors.
Loadbreak Hooks
Galvanized steel hooks are standard on all Type C cutouts,except the arc chute version, for use with a portable loadbreaktool. These sturdy hooks are mounted on the top support andserve to guide the fuseholder into the latch socket when clos-ing at an off-center angle.
Top Contact
The top contact is attached to the galvanized-steel hood by astainless rivet to provide a smooth self-aligning action duringclosing even in severely corrosive environments. The top con-tact provides a socket-type cavity for latching the fuseholderand prevents any possible “over-travel” of the fuseholder. Thetop contact is made of a highly conductive copper strip withsilver-plated embossments to resist corrosion. The contactsare held under constant pressure designed to maintain firmcontact with the fuseholder contact surface until fault inter-ruption is accomplished.
Hinge
The hinge on the Type C cutout employs large pivot areas forthe fuseholder’s trunnion and is cast of a copper alloy chosenfor its strength and corrosion resistance. The hinge contactsare highly conductive copper alloy stampings and are platedto assure low resistance current transfer from the trunnioncasting. The parallel current paths are backed up by highstrength cantilever springs and are riveted to the hinge cast-ings. Fuseholder can be dropped into place and easily liftedup and out. No tricky maneuvering.
Type C STANDARD Cutout
Chance Type C fuseholders are also mutually interchangeable with the S & C Electric Company’s Type XS cutout.

PRODUCT FEATURES
Interchangeability
Chance was the first to design a cutout that could interchangefuseholders and mounting assemblies with those of anothermanufacture. Standard Type C fuseholders and mounting as-
semblies are mutually interchangeable with the S&C ElectricCompany’s Type XS cutout (within the same voltage class).
Fusetube
The 1 / 2-inch inside diameter of the Type C cutout’s 100 amperefusetube increases internal pressure giving superior andreliable expulsion action. During frequently encounteredintermediate fault ranges this diameter also permits higherTRV (transient recovery voltage) values to be tolerated. Thissmall bore design eliminates any concern related to highimpedance phase-to-phase faults on ungrounded wye anddelta systems.
The inside liner is constructed of a synthetic arc-quenchingmaterial. The tube is made of fiberglass which permits the
smaller bore and provides a higher burst strength. It isprotected from the weather and environment by a specialultra-violet resistant coating.
Also, the Chance fusetube operates with fuselinks from allmajor suppliers.
Brackets
C cutouts come packed one per carton including a NEMAHeavy Duty “B” bracket with captive 11 / 2" bolt for crossarmmounting.
Type X brackets, also for crossarm mounting, provides 2 5 / 8"additional clearance between the crossarm and the cutout.
“D” brackets are used to mount cutouts and/or arrestersdirectly to the pole. Three brackets may be used for three-phase application. Type D brackets provide a clean, quickmounting without crossarm or special pole bands.
All the above brackets are galvanized steel for long lastingservice. Cutouts can be ordered without any brackets.
Higher Interrupt Capacities
By using a copper arc shortening rod inside the top of thefusetube, higher interrupt ratings are obtainable. An arcshortening rod is attached to the cap of some fusetubes andlowers the fuse link within the fusetube. This permits amuch shorter arc, resulting in less arc energy, and higher
interrupting capacities.For 200 A tubes, it allows for full voltage rating.
It is necessary to use fuse links with removable buttonheadswhen arc shortening rods are employed.
170 kV LIW (BIL)
A 170 kV BIL Type C cutout is available for use in areaswhere the 28.4-inch minimum leakage distance to groundis required. See ordering data, page 6.
Extra Corrosion Protection [150 & 170 kV LIW (BIL) only]
Type C cutouts are available with components of stainlesssteel inserts, hood and bolts, and copper alloy loadbreakhooks to offer greater corrosion resistance for environmentalareas where corrosion can become a major factor. To order astainless steel/copper alloy cutout add the suffix “S” to theend of the catalog number with the rating specifications de-sired. In additon, an optional spring assist may be providedto further enhance the toggle and drop out action in highlycorrosive applications.
Terminals
Tin-plated bronze parallel groove type terminals are standardon Type C cutouts. They can accommodate aluminum orcopper conductor sizes ranging from No. 6 (13.3 mm2) solidcopper through 4/0 (160.6 mm2) ACSR or 250 (167.5 mm2)kcmil stranded copper. The parallel groove design is perfectfor handling two different sizes of conductor as is the casewhen arresters are being used. Eyebolts are also available.See ordering data, page 10A-6.

22/36.4 kV - 170 kV LIW (BIL)
15 kv - 110 kV LIW (BIL)15/27 kV - 125 kV LIW (BIL)
All standard non-loadbreak fuseholders and the linkbreakfuseholders are interchangeable and fit into both the non-loadbreak and Type C LINKBREAK cutout mounting
assemblies produced after January 1985. Mounting as-semblies are same as Type C STANDARD cutouts, shownon page 10A-7.
Ratings / Specifications
The 15 kV Type C LINKBREAK cutout has a maximumdesign voltage rating of 15 kV. There are no voltage restric-tions on application to grounded wye, ungrounded wye, ordelta systems having maximum operating voltages (lineto line) equal to or less than the cutout maximum designvoltage rating.
The 15/27 and 22/36.4 kV Type C LINKBREAK cutouts havemaximum design slant voltage ratings. These cutouts are
to be used on systems which have phase-to-ground voltagesno greater than the value listed to the left of the slant (/)and which have phase-to-phase voltages no greater thanthe value listed to the right of the slant.
The Type C LINKBREAK cutout is to be used with onlyChance, McGraw-Edison and Kearney fuselinks. S&CElectric fuselinks and other fuselinks which require morethan 1 inch elongation before breaking must not be usedwith the Type C LINKBREAK cutout.
A sharp downward pull on the lever with a hookstickbreaks the fuselink.
15 kV - 110 kV LIW (BIL) unit
Application
The Chance Type C 100 amp LINKBREAK cutout provides
short circuit protection to utility lines with the added featureof mechanical linkbreak capability in a loadbreaking function.Linkbreak cutouts provide reliable protection from overloadsthat just melt the fuselink through the maximum interruptcapacity of the fuseholder and also provide inductive andcapacitive loadbreak capability. For loadbreak ratings seechart, next page.
The unit will also accept the Type C 200 amp non-loadbreakfuseholder or a 300 amp disconnect blade. Each LINK-BREAK cutout includes standard loadbreak hooks to usewith portable loadbreak tools. This method is particularlyuseful for switching of the 200 amp fuseholder and 300 ampdisconnect blade.
Design / Product FeaturesConstruction and product details shown on page 10A-3 applyto the LINKBREAK cutout except that the link-ejector onthe linkbreak fuseholder is a copper-alloy casting instead ofa stainless-steel stamping.
The unit utilizes a stainless-steel linkbreak lever to mechani-cally break fuselink elements thereby obtaining load inter-ruption within the fuseholder. The long lever is positioneddirectly in-line with the cutout, rather than on one side orin back of the cutout for convenient pull-down operation.

Application
The Type C Loadbreak Cutout is available for application on15, 25 and 35 kV distribution systems. The addition of thearc chute expands the flexibility of the Chance protectivedevices family by providing loadbreak capability for cutoutsand disconnect solid blade units. The loadbreak cutout pro-vides short circuit protection to utility lines with the addedfeature of a loadbreaking function.
The loadbreak cutout is applicable for transformer andcapacitor bank switching or line sectionalizing. Loadbreakcutouts provide protection from overloads that just melt thefuselink through the maximum interrupt capacity of thefuseholder. They also provide loadbreak capability through300 amperes.
Design
All design features and most components of the loadbreakunit are identical to those incorporated in the Type C stan-dard cutout. The loadbreak portion of the Type C Loadbreakcutout is a heavy duty, reliable load interrupter that providesa positive visible loadbreak. A common loadbreak mountingassembly will accept the Chance Type C 100 amp and 200amp loadbreak fuseholders or a 300 amp loadbreak discon-nect blade. The Type C LOADBREAK fuseholder is not de-signed to be interchangeable with any other manufacturer’scutout.
Ratings/Specifications
The 15kV Type C loadbreak cutout has a maximum designvoltage rating of 15kV. There are no voltage restrictions onapplicaton to grounded wye, ungrounded wye, or delta sys-
tems having maximum operating voltages (line to line) equalto or less than the cutout maximum design voltage rating.
The 15/27 and 20/34.5 kV Type C loadbreak cutouts havemaximum design slant voltage ratings. These cutouts areto be used on systems which have phase-to-ground voltagesno greater than the value listed to the left of the slant (/)and which have phase-to-phase voltages no greater than thevalue listed to the right of the slant.
Fuseholders and mounting assemblies from other manu-facturers' loadbreak cutouts are not interchangeable withChance loadbreak cutouts. Likewise, Chance fuseholdersand mountings are not interchangeable with other manu-facturers' loadbreak cutouts.
OperationThe self-contained loadbreak device enables the lineman tointerrupt load current by means of a simple hookstick opera-tion. To break the current, the lineman inserts a hookstickinto the operating ring and rapidly opens the device. Uponopening, a spring-loaded stainless steel blade mechanismsnaps out through a gray arc chute and elongates, cools andextinguishes the confined arc. The loadbreaking operationis independent of the operating speed of the lineman. Thefuse remains undamaged. No special or portable tools arerequired to operate the unit. In the open position, the fuse-holder or blade hangs in an approximate vertical positionfor the visible-break.
