★ It has multiple protection functions such as short circuit, locked rotor, overload, grounding, phase loss/imbalance, TE curve, startup timeout, external faults, etc
★ Monitor the three-phase current, zero sequence current, and three-phase current imbalance of the motor to achieve comprehensive protection of the motor, and have the function of recording protection events
★ Protection method: Relay protection output method, which is connected to the secondary operation circuit through the normally closed point (hard closed point) of the relay to achieve protection function
★ Wide range AC/DC universal power supply: AC/DC85～265V
★ 1 RS-485 communication interface (optical isolation), Modbus RTU communication protocol
★ 4-channel switch quantity optical isolation input, capable of external state quantity acquisition function, 3-channel relay protection control output, used for protecting tripping and fault alarm output functions, etc;
★ Display unit: Chinese LCD display, real-time reading of three-phase current measurement values and recording of protection events, protection parameters can be set by the display unit and communication software;

☆ 1 or 2 programmable DC 4-20mA analog outputs
☆ External zero sequence/leakage current transformer input, measure zero sequence/leakage current
☆ Three phase voltage measurement 380V/660V
☆ There are two types of current input, and users can flexibly choose according to their needs
1. Specialized small CT input (MT optional):
Below 15A (MT25), 15A-60A (MT100)
30A-90A (MT150), 60A-150A (MT250)
2. Use standard CT and MT5 in combination for 150A and above

Note: When selecting three-phase voltage, add measurement functions such as voltage, power, and electrical energy, as well as under/over voltage and under power protection functions
