New Tmax T4-T5.T Generation.

Preliminary - 1SDC210004B0202

BE FREE UP TO 630 A.

T ry to think of an installation which needs 630 A.Have you done that?

Now think of sizing it, selecting the apparatus, the accessories and of installing it.Right?

Now imagine being free to choose and free to work with much less, yes really muchless difficulty.Are you there?

If you’ve managed to imagine this, you’re ready to enter a new generation.You’re about to enter Tmax - the T Generation.

A NEW FREEDOM UP TO 630 A.

The new ABB SACE moulded-case circuit-breakers are called Tmax T4 and T5 and provide the performances

you’ve always wanted. High breaking capacity, Ics at 100% of Icu, high limitation of specific let-through energy -

performances which you were unable to find until today in circuit-breakers of these dimensions.

Designed up from the beginning to work together, they also offer you a complete series of thermomagnetic,

magnetic only and electronic protection releases, which are all interchangeable, as well as a new range of

accessories, among which are brand new residual current releases up to 630 A and the just as new stored

energy motor operator.

The new Tmax T4 and T5 are moulded-case circuit-breakers with the best performance/dimension ratios to be

found on the market, so can you imagine how much more space there is for cabling and how easily you can carry it

out, and, still further, the reduction in the switchgear dimension. But you’ll also find true allies for your job in the

terminals and accessories, with new, complete and standardised ranges.

Today with Tmax you’re even more free to choose: T1, T2, T3 up to 250A, and T4 and T5 up to 630 A.

Being free has never been so easy.

BE FREE TO RIDE THE MOST ADVANCED

T he Tmax circuit-breakers have been designed profiting by the experience which, for dozens of years,

has made ABB SACE recognised worldwide as a leader in constructing low voltage circuit-breakers.

It wasn’t easy to find the solutions which make it possible for the new Tmax T4 and T5 to achieve such high

performances in such limited dimensions. A high breaking capacity - Ics at 100% of Icu, and high limitation of

specific let-through energy, express the high technological level reached by these two new pieces of apparatus.

Thanks to latest generation electronics, T4 and T5 are born fitted with brand new electronic protection releases

with more functions, an integrated dialogue unit, a dedicated residual current release now up to 630 A and, for the

first time, the exclusive B type residual current release, sensitive to residual continuous and up 1000 Hz fault

currents.

Today more than yesterday, each installation, no matter what its type, has all the protection it needs.

Being free means this as well.

BE FREE TO CHOOSE OPTIMAL SIZING.

ore performance in less space. More applications, up to 630 A, with just two sizes. Easier selection of

the apparatus and the accessories. Optimal sizing of the installation and better protection of cables, busbar ducts

and supports. Less space needed in the metal structures. Less oversizing, i.e. lower costs. Less time for coordination

of installations. Fewer warehouse complications.

All the solutions needed can be selected with Tmax T4 and T5, even that of feeling more free to choose.

BE FREE TO DRIBBLE ROUND ALL INSTALLATI

aving apparatus available with smaller dimensions than all the others on the market, undoubtedly

offers great advantages. More space for cabling operations, simpler installation, more compact and standardised

switchgear compartments. Surely it isn’t necessary to explain how much time you will save?

The new Tmax T4 and T5 then continue down the road taken by the first three sizes of the family - T1, T2 and

T3: they, too, offer a complete range of terminals for all installation requirements, and unified and standardised

accessories.

Can you imagine circuit-breakers with reduced dimensions with ample and optimised terminal slots?

Can you imagine the freedom of selecting the protection releases even with work under way?

Have you any idea of the reduction in stock provided by having standardised accessories?

Being free also means having much more time for yourself.

TMAX. BE FREE.

ON DIFFICULTIES.

THE HIGHEST BREAKING CAPACITIES.The new Tmax T4 and T5 can be used in any application, even

the more unusual ones, thanks to their really exceptional

performances. Icu up to 200 kA at 415V, Ics = 100% of Icu, high

breaking capacities at 690V (80 kA), too, for the standard range,

as well as high Icu values for the range at 1000 V in direct current

and in alternating current, make T4 and T5 the ideal circuit-

breakers for all requirements.

JUST TWO SIZES UP TO 630 A.ABB SACE introduces two sizes: Tmax T4 up to 320 A and Tmax

T5 up to 630 A. All of these have really high rated current/volu-

me ratios and are made of top quality materials using innovative

construction techniques which guarantee the same performances

for all their versions: fixed, plug-in and withdrawable.

LATEST GENERATION ELECTRONICS.The technology is of the latest generation: the electronic PR221DS

and PR222DS/P protection releases for distribution and the

PR222MP motor protection release are brand new. The dialogue

unit incorporated in the PR222DS/PD release is also absolutely

new, and the dialogue function is added to its high protection

performances. Furthermore, the basic versions of the releases have

been enriched with more functions. And then what about the

accessories for the electronic

releases? The front display for

showing current is one of the

innovations along with auxiliary

contacts in electronic version,

which communicate directly

with the electronic release.

TMAX T4 AND T5.ONLY THE MOST ADVANCED TECHNOLOGYCAN ACHIEVE SUCH HIGH PERFORMANCE.

RESIDUAL CURRENT PROTECTION NOW REACHES 630 A.The new Tmax T4 and T5 residual current release offers a com-

plete protection solution for both installations and people for all

types of installation and is very simple to use and install. In fact,

residual current releases up to 630 A are available for all the fixed

and plug-in versions. Moreover, only ABB makes the RC 223

(type B) residual current release, sensitive to residual continuous

and up to 1000 Hz fault currents, available for the market:

a most important innovation,

and further witness to the

high quality and technological

standard achieved by ABB

SACE circuit-breakers.

HIGH LIMITATIONWith the new Tmax T4 and T5, high limitation of both the specific

let-through energy and the short-circuit peak current is obtained,

thereby truly making it possible to size the installation in the best

possible way and obtain better cable, busbar duct and relative

support protection, as well as that of all the coordinated apparatus

on the load side. High values are also obtained for back-up,

particularly useful

for sizing the

final parts of the

installation.

SELECTIVITY.For circuit-breakers with rated currents up to 630 A it is important

to reach high selectivity values and Tmax T4 and T5 guarantee

these high performances.

Being free to count on high selectivity values simplifies selection

of the circuit-breaker during the design of the installation, and

facilitates optimal sizing of all the apparatus.

MOTOR PROTECTION, FREEDOM OFCHOICE.With Tmax T4 and T5, the best solution

for motor protection up to 250 kW at 400

V AC can be selected. Alongside the

traditional solution, which uses a circuit-

breaker with magnetic only release,

contactor and external thermal relay, you

can now find an integrated solution, with

the circuit-breaker fitted with the new

PR222MP protection release and a

contactor. The PR222MP release is fitted

with all the protection functions, among

which are protection U against phase

unbalance and protection R against rotor

block.

Freedom of choice is not only provided by

the protection release. Freedom of choice

is also yours thanks to the high limitation

of Tmax T4 and T5, which allows optimal

sizing of the coordinated apparatus on the load side (contactor

and thermal relay – when present) as well as the power supply

cables.

ALL THE PROTECTION RELEASES.Tmax T4 and T5 have a wide range of both thermomagnetic and

electronic protection releases for all applications, even the most

unusual ones. Along with the traditional thermomagnetic releases,

there are also generator protection releases and magnetic only

ones recommended for motor protection.

The new generation of electronic releases has many new functions

even in the basic version. Setting the neutral protection to 50%

or 100%, an LED for signalling pre-alarm and alarm for the

protection against overload, are just

some of the innovation within the new

protection releases. The wide and fine

setting range of the protection thresholds

are, furthermore, a guarantee

of great flexibility of use and

optimal protection in any

installation.

INCREASINGLY COMPACT DIMENSIONS.The new Tmax T4 and T5 have the same height and depth, which

facilitates positioning them in switchgear compartments and

makes it possible to build increasingly compact and standardised

units.

And that’s not all: the limited dimensions allow greater access to

the terminals, and make all the connection and cabling operations

more convenient.

Available in all versions - fixed, plug-in and withdrawable - and

provided with a conversion kit from fixed to plug-in/

withdrawable, T4 and T5 are suited to constructing any

installation solution. Selection flexibility is guaranteed.

CONVENIENTLY ACCESSIBLE CONNECTIONTERMINALS.The terminal slots of the T4 and T5 circuit-breakers

are ample and optimised for all types of connection:

cables, busbars and cable lugs. A complete range of

connection terminals makes it possible to select those

most suited to the installation to be built. Standard

front (F), front extended (EF), front extended spread

(ES); front for copper cables (FC Cu), for

copper-aluminium cables (FC CuAl) and

multi-cable (MC) terminals, as well as rear

terminals (R), make all configurations possible.

With T4 and T5 you can build the exact

switchgear you had in mind.

TMAX T4 AND T5.ALL THE BENEFITS OF FLEXIBILITY ANDSIMPLE INSTALLATION.

INTERCHANGEABLEPROTECTION RELEASES.AT ALL TIMES.Thanks to ABB SACE’s design and

construction capacity, on the new

Tmax T4 and T5, the protection

releases of any type - magnetic

only, thermomagnetic or electronic

- can be replaced in complete

safety. The advantages?

Interchangeability of the releases

which therefore means terrific

versatility.

UNIFIED ACCESSORIES.As with Tmax T1, T2, and T3, the new Tmax T4 and T5 have

a complete, standardised and unified range of electrical

and mechanical

accessories, which

makes selection

easier, provides

flexibility of use

and reduces stock.

T1, T2, T3, T4 AND T5. THE TMAX PROJECT.That’s right: with the arrival of Tmax T4 and T5, designing and

building an installation up to 630 A has never been so simple.

All the Tmax apparatus starts out life distinguished by very high

construction quality, recognised over the years for all ABB SACE

products. The whole Tmax project, from T1 to T5, has basic

characteristics common to all the apparatus, such as double

insulation, the possibility of use in heavy-duty environments, and

a complete set of international certifications.

There are two depths up to 630 A: 70 mm for T1, T2 and T3,

103.5 mm for T4 and T5. Quality means this as well.

Today you have a family of circuit-breakers available for various

different fields of application. A power distribution range for the

protection of installations in direct and alternating current,

transformer and capacitor protection and a generator protection

range; a motor protection range for protecting asynchronous

motors up to 250 kW by means of circuit-breakers with currents

up to 400 A. And then, a range of circuit-breakers for protecting

installations up to 1000V in direct and alternating current for

applications such as road or railways tunnels, traction or mines.

And finally, the switch-disconnectors derived from the

corresponding circuit-breakers.

That’s really great freedom of choice, isn’t it?

INDUSTRIALIT. BORN TO INTEGRATE.IndustrialIT is the solution developed by ABB to integrate the

company activities at all levels, collecting together automation

and control systems, installation running and production

processes, design, marketing and sales, as well as the financial

and administrative activities, under a single management system

(AIP: Aspect Integrator Platform).

The products and technologies are certified according to the

IndustrialIT standard and grouped into about thirty functional

categories.
