Features:

• Two independent setting groups for phase and ground overcurrent protection (50/50N/51/51N).
• Three independent stages for phase and ground overcurrent protection, including negative sequence overcurrent protection (46).
• Inverse time overcurrent protection with IEC & IEEE curves (IEC-60255), cold load pickup, thermal overload protection (49), and broken conductor protection (46BC).
• Inrush blocking/unblocking, multi-shot (4-shots) auto-reclosing, trip circuit supervision (TCS), and password protection for all settings.
• Event and fault recording (100 events, 5 fault records with time stamping), disturbance recording with waveforms, 16×2 back-lit LCD display, programmable settings via local keys and remote port, and full communication with IEC 60870-5-103 and MODBUS protocols.
