Power distribution

The most common application for moulded case circuit breakers is power distribution. SACE Tmax XT can fit the needs with a complete range of solutions.
SACE Tmax XT1 and XT3 are designed to answer the most common requirements of installations. Frequently used in residential and commercial application, they are available in the fixed and plug-in versions with TMD thermomagnetic trip units.
SACE Tmax XT2 and XT4 meet requirements for more advanced applications. 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:

Ekip I and Ekip LS/I: basic trip units for standard applications.
Ekip LSI and Ekip LSIG: advanced trip units with more options to adjust protection functions thresholds, even electronically. Ground fault protection is available onboard and integration in a communication system is easy to obtain with Ekip COM module.
Ekip N-LS/I: basic trip unit with an oversized neutral protection for those installations where harmonic content is high.

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.

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 250A with operating voltages up to 690V 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. Current (class 1), voltage (±0,5%), power and energy (class 2) as well as power factor, frequency and THD are data that can be retrieved from the trip unit. By means of Ekip COM module for MODBUS communication, it is easy to send measurement and additional data to a supervision system.

Motor protection

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. 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. Magnetic only MF/MA trip units together with electronic Ekip M-I trip units can be coordinated with contactors and thermal relays for the most common solutions.
Ekip M-LIU and Ekip M-LRIU, available on XT2 and XT4, are the most advanced options to integrate protection functions onboard the circuit breakers. Protection against overload (with thermal memory) is guaranteed by selecting a trip class among 3E, 5E, 10E, 20E in accordance with IEC 60947-4-1. 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. 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. It is very common that prescriptions for generator protection are included in shipping registers, which is why SACE Tmax XT trip units’ curves have been designed to comply with them.

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. With the new series of SACE Tmax XT circuit breakers, ABB widens its range of solutions for generator protection:

Tmax XT2 and XT3 can be fitted with thermomagnetic (TMG) trip units with low thresholds for magnetic protection.
Tmax XT2 and XT4 have the additional option of an electronic trip unit, Ekip G-LS/I, with different protection curves form standard power distribution ones. Time of intervention have been fixed in accordance with main Naval Registers such as Lloyd’s Register of Shipping, Germanischer Lloyd, Bureau Veritas, Rina, Det Norske Veritas, Russian Maritime Register of Shipping, ABS.

Certifications and Shipping Registers

SACE Tmax XT circuit breakers and accessories are designed, manufactured and tested in conformity with:

IEC 60947-2 standard;
EC “Low Voltage Directive” (LVD) N° 2006/95/EC
EC “Electromagnetic Compatibility Directive” (EMC) 2004/108/CE
Main shipping registers such as Lloyd’s Register of Shipping, Germanischer Lloyd, Bureau Veritas, Rina, Det Norske Veritas, Russian Maritime Register of Shipping, ABS.

ABB SACE Quality System conforms to following Standards:

ISO 9001 international Standard;
EN ISO 9001 (equivalent) European Standards;
UNI EN ISO 9001 (equivalent) Italian Standards;
IRIS International Railway Industry Standard.

ABB SACE Quality System obtained first certification with RINA certification body in 1990.

Attention to protection of the environment is a priority for ABB SACE. Confirmation of this is an Environmental Management System certified by RINA in conformity with the International ISO14001 Standard. In 1999 the Environmental Management System was integrated with the Occupational Health and Safety Management System according to the OHSAS 18001 Standard and later, in 2005, with the SA 8000 (Social Accountability 8000) Standard, committing itself to respect of business ethics and working conditions.

ISO 14001, 18001 and SA8000 recognitions together with ISO 9001 made it possible to obtain RINA Best Four Certification.
