3. Protection functions
The protection relay offers overcurrent and thermal overload
protection, earth-fault and phase-discontinuity protection for
cable feeders, and three-pole, multi-shot autoreclose functions
for overhead-line feeders.
Enhanced with optional hardware, the protection relay also
features two light detection channels enabling arc fault
protection of the switchgear, busbar system and cable
terminals.
The numerical feeder protection relays of the 610 series
support a wide range of standard communication protocols,
among them the IEC 61850, IEC 60870-5-103, Modbus,
Profibus and DNP3 communication protocols.
