1) Measurement function
Electrical parameter measurement: It can measure the three-phase voltage, current, active power, reactive power, power factor, phase angle, frequency, total active power and total reactive power of A, B, and C.
Power quality measurement: It can measure the 2-21st harmonic content and total harmonic content of A, B, and C three-phase voltage and current, and calculate the voltage qualification rate.
2) Metering function
Energy metering: It can measure the total import and export of A, B, and C active energy, and four-quadrant reactive energy.
3) Load freeze
Freeze various electrical parameters and energy for 15 minutes.
4) Daily freeze
It can record the maximum phase and extreme value of residual current in the past 31 days and the past 512 residual current records.
5) Event record
It can record the total number of trips, residual current exceeding the limit, protector self-test, protector tripping and other events in the last 10 times.
6) Data collection function
It can collect data from external temperature and humidity sensors, water immersion sensors, etc.
7) Event reporting function
Active power outage reporting: Actively report power outage information when a power outage occurs.
Active event reporting: Report switch status and fault type when an event occurs.
8) Interface function
It has an indication interface, display interface, local communication interface and remote communication interface.
9) Control function
It has remote and local opening and closing functions. It will automatically trip when the residual current exceeds the limit and automatically reclose after the residual current exceeds the limit. Other faults require manual closing.
10) Protection function
Leakage protection, short circuit protection, overload protection; overvoltage protection, undervoltage protection and overtemperature protection (configurable).
