Overcurrent and directional earth fault protection relay.It offers protection for neutral currents and optionally for installations with isolated neutral systems.
Auxiliary power supply (24-220 Vdc / 48-230 Vac).
Protection functions: (2) 50 + 50/51 + (2) 50N/G + (2) 50N/51N/67N(1) + 52 + 50BF + 79 + 74TCS + CLP + 86 + 49T + 59N. Optionally, directional isolated neutral overcurrent (2) 67NI.
It includes switch disconnector protection function by means of trip blocking.
5 attempts of reclosing with 79 protection function (Recloser). Direct signalling/control of function 52 (Circuit breaker) and function 79 (Recloser).
Metallic box with high electromagnetic compatibility level (EMC) and wide range of operating temperature.
5 oscillographic records, 20 fault reports and non-volatile RAM memory: stores 200 events without power supply thanks to its internal RTC (Real Time Clock).
1 rear port on the back with the following options respect to communication protocols:
- One rear port RS485 with IEC60870-103 or Modbus RTU selectable by settings.
- One rear port RJ45 with IEC 61850, DNP 3.0 TCP/IP or IEC 60870-5-104 (depending on the model).
