Combination Heavy Duty StartersFeatures and BenefitsCombination StarterFeaturesCombination starters includethe following features:▪ Manufactured with Cold Forming“TOX” Process▪ Solid State Overloads Standard onSizes 5–8▪ Easy to Install▪ Wide Range of Enclosure TypesAvailable▪ Heavy Duty Quarter Turns▪ 100kA Short Circuit Current Ratingwhen Protected with Class R Fusesto 600V or MCP to 480V▪ Visible Blade Disconnect▪ Industrial Type Disconnect HandleApplicationA combination starter meets NationalElectrical Code requirements for:1. A means of providing short circuitmotor protection with fused or breakerdisconnection of line voltage.2. A means of safeguarding personnelfrom contact with live parts and fromaccidental starting of machinery bydisconnecting the motor and thecontroller.3. A motor controller with overloadprotection.Prewired combination starters eliminatethe cost of wiring between separatedisconnect and starter. Factory testingassures field performance. Combinationstarters also provide a more compactand attractive installation than separateunits.Enclosure TypesCombination starters are available inNEMA 1, 12/3/3R/4 (painted), 4/4X(stainless), 4X fiberglass and 7 & 9enclosures. Enclosures protectpersonnel from contact with live partsand depending upon the construction,protect the control in varying degreesfrom physical damage and harmfulatmospheres. All enclosures aresupplied with corrosion resistantfinishes.New Heavy Duty Disconnect SwitchesThe disconnect switch that goes thedistance in durability, performance andreliability has been made even better togive you greater advantages:▪ Visible blades for the highest levelof safety▪ Double break switching action toreduce arcing, increase lifetime andeliminate the “electric hinge”▪ More rugged positive action switch▪ Oversized lugs are standard▪ Line side shield to help guardpersonnel from contact with live parts▪ Higher horsepower rating fordesign E high efficiency motors▪ Now UL listed for IIsco, Burndy andT&B crimp type lugs▪ The 200A switch now accepts up to300 MCM versus 250 MCM wire sizeIts rugged construction - with a highfault withstand rating of 100kA at 600VAC when fused with class R ratedfuses - meets the most stringentindustry standards set forth by theautomotive, petro-chemical, and pulpand paper industries. UL recognized andCSA certified, our disconnect switchesare available either non-fusible or fusiblewith class R and class J fuse clips.Enclosure Kits for NEMACombination Starters DescriptionNow you can assemble a non-stockedcombination starter per your unanticipatedneeds in minutes. Say, forexample, your customer needs a fusiblecombination starter that you don’t havein stock. You need in now, but don’tsweat it. Simply start with the newlyoffered enclosure kit which has theGeneralhandle preinstalled. You install therequired starter and fusible disconnect,connect the power wire and you arefinished. Within minutes, you have therequired combination starter in yourhands. No more waiting on the factory.You need it, your got it!What Is In It For You!▪ Reduce Lead-time - What used totake days to get now takes minutes▪ Reduced Inventory - Instead ofstocking scores of various combinationstarters, simply stock a fewenclosure kits, disconnect kits, circuitbreaker kits and open starters. Withthese basic “building blocks” youvirtually have hundreds of productson-hand▪ Quality - The same high level ofquality you have been accustomedto with our products will also befound in these new enclosure kits▪ UL Listed - By correctly followingthe instructions included with the kits,the product you build isUL/CSA ListedRefer to page 16-90 for more details.Siemens Type ETI Circuit BreakerThe ETI circuit breaker is a devicedesigned specifically for applicationin motor circuits. The ETI is a magneticonly protective device designed toprovide protection against shortcircuit current.The instantaneous-only type ETI circuitbreaker employs adjustable magnetictrip settings to allow broader applicationranges and a higher degree of motorshort circuit protection.Heavy Duty StartersThese combination starters use thesame starters described in the heavyduty starter section of this catalog.ESP 100 solid state overload startersand ambient compensated bimetaloverload starters are available.16 CONTROLPRODUCTSNEMA & GeneralPurpose ControlSiemens Power Distribution & Control, SPEEDFAX 2007-2008 Product Catalog 16-17
