★ It has multiple protection functions such as short circuit, locked rotor, grounding, phase loss/imbalance, TE curve, etc
★ Measure three-phase current, zero sequence current, and three-phase current imbalance 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, Modbus RTU communication protocol
★ 8-channel remote signal input with switch quantity, 4-channel relay control output
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;
★ Extended display unit: Real time display of measured electricity, on-site setting of protection parameters
Seven button Chinese LCD display unit

☆ Dual RS-485 communication interface
☆ 1 programmable DC 4-20mA analog output
☆ Profibus DP communication interface
