PROTECT ION TR I P UNI TS

— All protection trip units in the SACE Emax 2 family are self-powered by current that crosses the circuit breaker. They provide excellent reliability due to a system of self- control of internal connections. The setting, testing and downloading of reports can be carried out directly from a Smartphone, Tab- let or PC. In addition, the commissioning stage can be further accelerated, minimizing the possibility of errors, by directly configuring the protection trip unit with the DOC design software settings. Car- tridge-type modules that are easily installed on- board enable the units to be integrated into the most complex systems. Additional functions can be created, such as: • Synchrocheck , to check the synchronization of the two half-busbars before enabling circuit- breaker closing;
• Communication with all supervision systems available in the Modbus, Profibus and DeviceNet™ protocols as well as the modern Modbus TCP, Profinet, EtherNet/IP™ protocols; • Integration into Smart Grids thanks to the possi- bility of communicating without the assistance of any external converter, according to standards (IEC 61850) already in use in the automation sys- tems of high and medium voltage substations; • Multi-voltage supply module , which enables the protection trip unit and modules to be supplied with any auxiliary voltage available in direct or al- ternating current; • Programmable logic management with Ekip Sig- nalling modules that provide a high number of electrical input and output contacts; • Logical interlocks between circuit breakers, which can be achieved with the Ekip Link proprietary communication protocol, avoiding complex wir- ing due to the transmission of all signals via a bus.
