Tmax XT moulded case circuit breakers guarantee an extremely high performance level while being progressively smaller in size, simple to install and able to provide increasingly better safety.

ABB, the leading power and automation technology group, has today opened a new advanced manufacturing facility in Senatobia, Mississippi, to produce electrical components for the US market.

ABB control and protection low voltage products are IE3 ready. Our motor control solutions for high-efficiency motors can save you significant panel space. Learn more! The Tmax XT range is composed of four frames up to A to cover all possible applications. Ekip is the name of the range of electronic trip units and all the associated electronic accessories. These trip units are easily interchangeable and can be mounted simply by using a few screws in the lower section.

The electrical accessories, opening coils and auxiliary contacts can be mounted simply by applying pressure to insert them, without the use of screws. Discover the range of mechanical accessories. A wide range of terminals for all installation requirements is available, including terminals for slots, terminals for busbars, rear terminals and rear adjustable terminals.

The most common application for moulded case circuit breakers is power distribution. Frequently used in residential and commercial application, they are available in the fixed and plug-in versions with TMD thermomagnetic trip units. A wider range of trip units is able to support a better customization of the protection functions.

TMA thermomagnetic trip units with adjustable thresholds for overload and short circuit protection are a good option for DC applications.

New Ekip electronic trip units take care of any AC application:. During the last years, the growing attention to the environmental issues together with new policies of cost reduction, which involve not only capital costs but also operational costs, has led to a wider diffusion of the energy measurements practice down to the lower distribution levels. Aim of this tendency is to get to an optimal load management and to identify possible system inefficiencies.

Examples of these loads can be machinery, any subparts of an industrial plant, the various modules that compose a data center as well as the different consumptions of a conditioning system in a mall. The possibility to measure, transmit and store data about each load is fundamental. Ekip E-LSIG trip unit for Tmax XT4 has been designed to protect loads ranging from 16A to A with operating voltages up to V against overloads, shot circuits, ground faults, over and undervoltages.

At the same time, without the need of any external module or sensor and without increasing the installation dimensions, Ekip E-LSIG can provide measurements of the main electrical quantities. Motor protection is one of the most common application for moulded case circuit breakers in low voltage installations. Safety and reliability of solution are important aspects that must be considered when choosing and manufacturing a system for starting and monitoring motors.

Start-up is a particularly critical phase for the motor itself and for the installation powering it. Use of generators is no longer occasional and limited to short periods, but it has become continuous and no more subject to long stoppage periods. For this purpose, it is indispensable to guarantee adequate protection of the electric plant.

Protection against overload: circuit breaker must be selected and set so that it trips before temperatures damaging insulating materials are reached.

Product standards stipulate that, for a specified time, the generator must be able to carry a given current higher than the rated current. Protection against short-circuit: the short-circuit current of a generator decreases over time and its initial value is about 3 - 5 times the rated current of the generator itself. To detect a fault within a suitable time and disconnect the generator, it is necessary to select circuit-breakers with low magnetic trip thresholds or circuit-breakers fitted with electronic trip units with adjustable threshold.

Power distribution The most common application for moulded case circuit breakers is power distribution.

Ground fault protection is available onboard and integration in a communication system is easy to obtain with Ekip COM module. Energy metering During the last years, the growing attention to the environmental issues together with new policies of cost reduction, which involve not only capital costs but also operational costs, has led to a wider diffusion of the energy measurements practice down to the lower distribution levels. Motor protection Motor protection is one of the most common application for moulded case circuit breakers in low voltage installations.

When it comes to direct starting, ABB SACE proposes two different solutions: a conventional system with three poles circuit-breaker equipped with a magnetic only trip unit for protection against short-circuits, a thermal relay for protection against overloads and phase failure or imbalance, and a contactor to operate the motor; an advanced protection system onboard the circuit breaker which integrates all the protection and monitoring functions, and a contactor for operating the motor.

Tmax XT is covering both solutions thanks to its range of motor protection trip units. Protection against overload with thermal memory is guaranteed by selecting a trip class among 3E, 5E, 10E, 20E in accordance with IEC Protection U against phase unbalance, R against rotor lock, and G against ground faults can also be available. Generator protection Use of generators is no longer occasional and limited to short periods, but it has become continuous and no more subject to long stoppage periods.
