★ It has multiple protection functions such as short circuit, locked rotor, overload, grounding, phase loss/imbalance, underload, TE curve, under/overvoltage, startup timeout, acceleration trip before startup, power loss during operation, external faults, etc
★ Measure three-phase current, zero sequence current, three-phase current imbalance, three-phase voltage, zero sequence voltage, three-phase voltage imbalance, active/reactive power, power factor, frequency and other electrical quantities to achieve comprehensive protection of the motor, and have the function of recording protection events
★ Active energy (kWh) and reactive energy (kVARh)
★ Three adjustable protection control output modes:
1. Direct starting method 2, frequency converter control method
3. Multi site control mode
★ Wide range AC/DC universal power supply: AC/DC85～265V；
★ 1 RS-485 communication interface, Modbus RTU communication protocol
★ 11 channels of switch remote signaling input, 5 channels of relay output
★ Three phase current measurement and SOE recording, real-time reading through communication interface, protection parameters can be set by display unit and communication software

☆ Extended display unit: Real time display of measured electricity, on-site parameter setting
Four button Chinese LCD display unit
Remote display control unit for multiple locations
☆ Dual RS-485 communication interface
☆ 1 programmable DC4-20mA analog output
☆ Restart after losing pressure
☆ Profibus DP communication interface
☆ DeviceNet communication interface
☆ External zero sequence/leakage current transformer input, measure zero sequence/leakage current
☆ 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

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