Features:

• Two independent setting groups for phase and ground overcurrent protection (50/50N/51/51N), with three independent stages.
• Negative sequence overcurrent protection (46), inverse time overcurrent protection (IEC & IEEE curves), cold load pickup, thermal overload protection (49), and broken conductor protection (46BC).
• Switch On To Fault (SOTF) protection, inrush blocking/unblocking, multi-shot (4-shots) auto-reclosing, and trip circuit supervision (TCS).
• Password protection for settings, event recording (100 events), fault recording (5 events with time stamping), disturbance recording with waveforms and status, and 16×2 back-lit LCD display for settings.
• Programmable settings via local keys or remote communication, full communication with IEC 60870-5-103 and MODBUS protocols, and measurement of primary/secondary current, symmetrical components, thermal state, and I2/I1 ratio (broken conductor).
