SIL-A Overcurrent and Earth Fault Relay for Primary and Secondary Distribution Main characteristics The SIL-A is an overcurrent and earth fault protection relay for primary and secondary distribution with power supply 24-22 Vdc/ 4-23 Vac. The current measurement is obtained either by standard Many protection functions: (Zone Selection Interlocking) To allow the relays have a communication port on the front of the equipment and
5 Oscillographic records, 2 fault reports and 2 events saved in non-volatile RAM memory with date/time, even without power supply, thanks to its internal RT (Real Time lock).
