★ 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
☆ DeviceNet communication interface
☆ 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. Standard CT (1A/5A) is used for 150A and above
☆ External zero sequence/leakage current transformer input, measure zero sequence/leakage current

Note: Only one of Profibus DP, DeviceNet, and dual RS-485 communication can be selected
