1 Technical catalogABBmolded casecircuit breakersUL 489 and CSA StandardPreliminary - 1 SDC210003D0202 Tmax, Isomax, Emax: IndustrialITenabled!For further information, go to the Products and services/Industrial ITsection on our web site: * All product Technical data and related documentation can be found inInternet and is accessible to the customer. The standard documentationis in English, but there are local language versions for each country wherea given product is the solution developed by ABB for the all-round integration of a company s activities, where eachproduct is seen as part of a complete solution. Productsand technologies are grouped intofunctional categories (Suites), eachof which measures,controls, optimizes andsupports a specific block of activities, andthey can ensurecoordinated interactionthanks to the platformcreated by ABB (AIP: Aspect Integrator Platform).

2 In addition to interactivity between certified products,every certified product also guarantees the readyavailability of all the information needed for it tofunction - Technical characteristics, installationinstructions, use and maintenance instructions,environmental certificates and declarations, all updatedto the latest version .. a considerable advantage for theuser*.The whole range of TmaxandIsomax molded case andEmaxpower circuit breakers has obtained IndustrialITcertification and is fully entitled to join the ProtectITsuiteof circuit breakers combine with about 700 productsin the ranges of distribution boards, thusenabling complete switchboards to beassembled using all IndustrialIT-certifiedcomponents.

3 Moreover, T4 and T5feature e-plug communicationinterface, which allows Integrationto IndustrialIT , Isomax and Emax circuitbreaker can be integrated with theconfigurable ABB products in a system: thiscompatibility has always been a fundamental premise ofthe ABB design process. Mass customization, themass production of components customized to meet agiven buyer s specific needs is already feasible, asIndustrialIT certification again, ABB is ahead of the field in offering a betterand better customer service!OVERVIEWMAINCHARACTERISTICSTHE RANGESACCESSORIESCHARACTERISTIC CURVESAND TECHNICALINFORMATIONWIRING DIAGRAMSOVERALLDIMENSIONSCOMPLETE AND PERFECTLY INTEGRATEDIn the range of molded case circuit breakers conforming with the UL 489 and CSA Standard, ABB proposes anentire range which covers current ratings between 15 A and 2500 A and interrupting ratings, at 480 V AC, which canreach 150 ranges available are as follows: circuit breakers for power distribution (fitted with thermomagnetic or electronic trip units starting from 100 A) circuit breakers with adjustable magnetic only trip units for motor protection (MCP.)

4 Motor Control Protection) molded case switches for use as isolators or switching devices for lines, busbars or parts of a plant (MCS: molded case Switch)With the introduction of the new Tmax UL series, a single-pole circuit breaker with interrupting rating of 18 kAat 277 V AC is available on the American market for the first VAll ABB circuit breakers in accordance with theUL 489 and CSA Standard can beused in installations with wye or deltadistribution systems since use of the circuitbreaker at 480 V AC is guaranteed, evenfor the smallest Tmax T1 DIMENSIONSABB molded case circuit breakers ensurehigh performances in extremely small andcompact dimensions.

5 Standardization ofthe depth of the smaller sizes allows morerational and less deep enclosure to be usedthan in the INSULATIONT hanks to the double insulation technique,with all ABB molded case circuit breakers *the electrical accessories can be mounteddirectly on field with the circuit breakerinstalled: this allows considerable savings intime and therefore in costs.* Except for Isomax Tmax T4 and T5 circuitbreakers have obtained theprestigious INTEL Design 2003 Augusto Morello award in theProduct Technologies andProduction processes GENERATIONTmax has grown. ABBexperience in designing andmanufacturing molded casecircuit breakers has made itpossible to create circuit breakerswhich, up to 600 A, allow any application to befaced practically and new Tmax have been thought up to worktogether, to help you carry out selections andcorrect sizing, to make installation simpler, butabove all to give you top level latest generation technology is present forthe first time even in the smallest Tmax you have everything you need athand to make your job easier, from all types ofaccessories and terminals.

6 The T Generation grows,and so does FREE TORIDE THE was not easy to find solutions which would allow theTmax circuit breakers to achieve such high performancesin such limited dimensions, but thanks to theexperience which has been recognised to a leadersuch as ABB for decades, the objectives we had setourselves have been achieved. So this has meantbeing able to equip such a small circuit breakeras the T2 with an electronic trip unit, to fit thecircuit breakers with new arcing chamberswhich allow the arc extinction time to bereduced, or, still further, to provide doubleinsulation for ever greater safety right from thesmallest size.

7 A complete series of latestgeneration trip units is available, from theelectronic to the thermomagnetic or magneticonly ones - all new Tmax T4 and T5 are an example of thegreat technology expressed by this family of circuitbreakers with high breaking capacity and highlimitation of the specific let-through free is also all the circuit breakers in the Tmax family come fromoptimisation of installation sizing. With T1,T2 and T3you can find the ideal product for sizing an installationup to 225 A, and with T4 and T5 up to 600 , with the latter, high selectivity valuesare obtained for optimal coordination with othercircuit breakers .

8 You can also choose the bestsolution for motor protection with the motorcontrol protection (MCP).Higher performances in less space. Moreapplications up to 600 A. Easier selection of thecircuit breakers and accessories. Optimal sizing ofthe installation and better protection of cables,busbar ducts and supports. Less space required inthe switchgear and in the metal oversizing and therefore lower time for coordinating the stock complications. With Tmax, all thesolutions needed can be chosen, as well as thatof feeling freer to FREE TOCHOOSEOPTIMAL circuit breakers available with smaller dimensionsthan all the others on the market undoubtedly offersgreat advantages - more space for cabling operations andsimpler installation, therefore notable savings in time -five sizes, just two depths - inches (70 mm) forT1, T2, T3 and inches ( mm) for T4and T5, and the latter also have the same are also available in all the versions: fixed,plug-in and draw out and, thanks to special kits,passing from a fixed circuit breaker to a plug-in/draw out one is child s play.

9 Flexibility of use overthe whole series is ensured by the complete rangeof connection terminals and by the large numberof free also means having much more timefor FREE TODRIBBLE ROUNDALL UL RATED circuit BREAKERSThe 100% rated versions for Isomax circuit breakers are available thanks to the excellent thermal sizing ofthe THE APPLICATIONSABB offers the right solution for any application up to 2500 A thanks to Isomax S6, S7 and S8 circuitbreakers, perfectly integrated with the Tmax family: MCCB: S6, S7 and S8 molded case circuit breakers for power distribution; MCP: S6, S7 and S8 circuit breakers with magnetic only trip unit for motor control protection; MCS: S6, S7 and S8 molded case switches for using as isolators or switching devices for lines, busbars or parts of VERSATILITYI somax circuit breakers can be fitted with a wide range ofterminals for every kind of connections.
