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.

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

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?
