From circuit breaker to power manager
A size for every requirement.
SACE Emax 2 series air circuit-breakers offer tailored performance to meet the demands of today’s installations. Four sizes are available for creating switchgear of compact dimensions and high performance, with busbars of optimized length and cross-sections.
4 sizes
The SACE Emax 2 range is made up of 4 sizes: E1.2, E2.2, E4.2 and E6.2 up to 6300A, which enable switchgear of compact dimensions and high ratings to be built, with busbars of reduced length and cross-section.
The protection trip units, auxiliary connections and main accessories are the same throughout the range to simplify design and installation. Furthermore, the sizes from E2.2 to E6.2 have the same height and depth.
The rating levels are updated and uniform throughout the sizes to meet the demands and needs of today’s installations, from 42kA to 200kA, and to standardize switchgear projects.
High short-time currents, together with the efficiency of the protection functions, guarantee complete selectivity in all situations.
Accurate design and choice of materials enable optimization of the overall dimensions of the circuit-breaker. In this way switchgear of compact dimensions can be built and outstanding savings at the same performance can be obtained.
Power Controller
The exclusive Power Controller function available on the new SACE Emax 2 circuit-breakers monitors the power managed by the circuit-breaker, keeping it below the limit set by the user. As a result of this more effective use, the peak of power consumed can be limited allowing savings on electricity bills.
The Power Controller, patented by ABB, disconnects non-priority utilities, such as for example electric car charging stations, during the times when consumption limits need to be respected, and connects them again as soon as it is appropriate. When required, it automatically activates auxiliary power supplies such as generator sets. No monitoring system is required: it is sufficient to set the required load limit on Emax 2, which can control any circuit-breaker located downstream, even if it is not equipped with a measurement function. In installations that are already equipped with energy management systems, the load limit can also be modified remotely.
Ekip Touch
SACE Emax 2 circuit-breakers are equipped with a new generation of protection trip units that are easy to programme and read. The Ekip Touch trip units measure power and energy with precision and save the most recent alarms, events and measurements in order to prevent faults to the installation or trip effectively when necessary.
Network Analyzer
On request, the Network Analyzer function is also available, which controls the quality of absorbed power in real time and with extreme precision.
In addition, the innovative Ekip Touch and Hi Touch trip units in the G version include all the functions of generator protection switchgear, offering a safe control solution that is ready to use.
No external devices, wiring and inspections are required.
