Complete Protections:  integrating protection, remote monitoring, remote signaling, remote control together;

Measuring Function: it can measure current, voltage, active power, passive power, power factor, frequency, electrical degree and so on;

LED Display: it can display data, failure, fixed-value parameters, man-machine interface (infrared remote control and button menu operation) in realtime;

Protection Functions: it has protection functions of over-voltage, under-voltage(delay), three-phase short-circuit current, inverse time lag current, leakage, insulation monitoring and so on;

Communication Function: it provides RS485 communication interface to realize transmission functions of remote monitoring, remote signaling, remote control, fixed-value setting for protection and enquiry, working status of device, event record, recorded wave data and so on;

Event Record: it can record 32 online events, FIFO, dynamic refresh with time mark, no lose when power supply cutting-off;

Time Function: it can display time in realtime and change time locally and automatically calibrate time by centralized remote control;

Failure Record Wave Function: It can record current, voltage, breaker’s status and protection status before, during and after failure with 12-cycles record length completely and exactly, providing evidence for failure analysis.
