BE FREE TO SIZE ANY TYPE OF INSTALLATION IN AN IDEAL WAY AT ALL TIMES.
Thanks to the seven sizes and a complete series of magnetic only, thermomagnetic and electronic trip units. And also a wide range of accessories and the possibility of selecting dedicated ranges for all market applications, even the most specific and advanced ones.
BE FREE TO INSTALL ALL THE SIZES WITHOUT ANY DIFFICULTY.
T Generation is undeniably the family of moulded-case circuit-breakers with the top performance/size ratio available on the market, so can you imagine how muchmore space there is for cabling and how simply you'll be able to carry it out? And further, what about the reduced dimensions of the switchboard?
BE FREE TO RIDE THE MOST ADVANCED TECHNOLOGY.
It is thanks to this technology that T Generation offers you performances which were out of the question until now in circuit-breakers with these dimensions. And there are some exclusive technical solutions which only ABB SACE can offer you, such as the brand new electronic trip units designed for the new Tmax T7 or the new rapid accessory fitting system.
FREEDOM OF TOTALLY SAFE SELECTION.
The safety of knowing that behind Tmax there's ABB SACE's strong and constant commitment to continually search for excellence of quality at the base of each product and service. ABB quality.
TMAX T1,T2 AND T3
ALL SOLUTIONS PERFECTLY COORDINATED, UP TO 250A.
Tmax T1, T2 and T3 – the three “little ones” of the Tmax family - were thought up from the beginning to work together. You can select functions and performances which until now couldn't be found in circuit-breakers with these dimensions. Perfect up to 250 A.
There are so many characteristics common to the three sizes. The single depth (70 mm) of the three pieces of apparatus making installation truly simpler, the new arcing chambers produced with a gasifying material, and an innovative construction system allowing the arc extinction time to be reduced. All three sizes are fitted with adjustment of the thermal threshold as standard and have new - three-pole and four-pole - residual current releases, designed and constructed to optimise space in the switchboard and simplify coupling with the circuit-breaker. Tmax T1, T2 and T3 have a completely standardised range of accessories.
TMAX T1. THE LITTLE ONE THAT'S REALLY BIG.
Thanks to its extremely compact dimensions, Tmax T1 is a unique circuit-breaker in its category. Compared with any other circuit- breaker with the same performance (160 A – up to 36 kA at 415 V AC), the overall dimensions of the apparatus are notably smaller.
TMAX T2. INTELLIGENCE AND HIGH PERFORMANCE IN THE PALM OF YOUR HAND.
Tmax T2 is the only 160 A circuitbreaker available with such high performances in such very limited overall dimensions. A breaking capacity of 85 kA at 415 V AC can be achieved. Tmax T2 can be fitted with a latest generation electronic trip unit.
TMAX T3. 250 A IN A DEPTH OF 70 MM FOR THE FIRST TIME.
Tmax T3 is the first circuit-breaker which carries 250 A in considerably limited overall dimensions compared with any other similar apparatus – a really large step forward for this type of equipment.
Tmax T3 allows coordinations for motor protection to be made up to a power of 90 kW at 415 V AC.
TMAX T4,T5 AND T6
BE FREE TO CHOOSE UP TO 1000A.
Tmax T4, T5 and T6 are the moulded-case circuit-breakers with the best performance/size ratio on the market. Their application possibilities are practically unlimited, thanks to their dedicated and specific ranges, advanced electronics, as well as a complete and standardised range of accessories. The top quality materials and innovative construction techniques used by ABB SACE mean Tmax circuit-breakers can guarantee truly exceptional performances, with a really high rated current/ volume ratio. For example, T4 and T5 guarantee a breaking capacity up to 200 kA at 415 V AC and an extraordinary 80 kA at 690 V AC. Moreover, they complete the range of applications up to 1150 V in alternating current and 1000 V in direct current.
The series of electronic trip units, equipped with latest generation technology, offers solutions exclusive to ABB. T4, T5 and T6 have the same depth, simplifying their positioning in the switchboard compartments, and also have a complete, standardised and unified range of accessories available, simplifying selection, making them flexible to use and reducing stocks.
NEW PR223EF TRIP UNIT. THIS IS WHERE THE EXCLUSIVE INNOVATION IS TO BE FOUND.
The new PR223EF trip unit with the EFDP system offers two characteristics which until now were antithetic: selectivity and rapid tripping. With the new PR223EF, a new range up to 1000 A has been conceived for specific needs requiring high selectivity values: rapid
detection of the fault and no limit to the number of hierarchical levels of the distribution plant. With the EFDP system, the size of the apparatus inside the installation can be reduced and cable and busbar sizing can be optimised. And the outcome? Considerable reductions in plant costs.
NEW PR223DS TRIP UNIT. FREEDOM OF CONTROL.
The new PR223DS trip unit has been conceived and built for power distribution circuit-breakers. Now all the different electrical values of the
installation can be measured. And that's not all – there are LEDs available on the front of the trip unit which signal some configurations and the presence of any alarms (overload, incorrect connections, etc.).
FREEDOM TO THE Nth POWER.
The new Tmax T7, available in two versions up to 1600 A either with manual operating mechanism or motor operator, was conceived with a really revolutionary design for circuit-breakers of this type: advanced electronics, exceptional performances and new installation and accessory fitting solutions.
Flexibility is absolutely exceptional with Tmax T7: they can be installed both vertically and horizontally (in the withdrawable version, too), there are all types of terminals (among which, flat orientated rear terminals) and a new, faster and safer racking-out system for the moving part. Moreover, cabling is considerably facilitated by the reduced height.A great news is the new rapid accessory wiring system. No wires inside the circuit-breaker, rapid, simple and safe connection to the external circuit, and no screws for fixing the external power supply cables.
The exclusive news of the new cable interlock provides notable benefits in terms of optimal sizing. By using this accessory it is possible to interlock two circuit-breakers in any position and, above all, to interlock a T7 with an air circuit-breaker as well. Impossible until today, this answer is ideal for automatic transfer switch solutions.Special attention has been paid to the electronics and the results are there to be seen … PR231, PR232, PR331 and PR332 are the new interchangeable electronic trip units, with modularity and rating-plugs which can be replaced by the customer.
The PR231 and PR232 trip units, with dip-switches for setting the protection thresholds, offer LEDs to signal protection tripped for each protection function: this means the reason for circuitbreaker tripping can always be found.
The PR332 is decidedly ahead of its time in the present reference panorama: fitted with a large graphic display, it allows all the information needed to be displayed simply and clearly. It also offers advanced protection functions (as well as the “classic” protection functions). For example, the exclusive data logger function allowing all the events and values before the fault to be recorded for later analysis.
