★ It has multiple protection functions such as short circuit, locked rotor, reverse time overload, grounding, phase loss/imbalance, TE time, etc
★ Monitor the three-phase current, zero sequence current, and three-phase current imbalance of the motor to achieve protection for the motor
The relay protection output is a protection trip mode, completely replacing conventional thermal relays, and is connected to the secondary operation circuit through the normally closed point of the intermediate relay
★ Wide range AC/DC universal power supply: AC/DC85~265V
★ Equipped with RS-485 communication interface (optical isolation) and Modbus RTU communication protocol
★ 3-channel switch light isolation input, capable of collecting external state variables,
★ 3-channel relay protection control output, used to protect tripping and fault alarm output functions, etc;
The measurement values of three-phase current and the recording of protection events are read in real-time through the communication interface, and the 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
Digital LCD display unit/Three button Chinese LCD display unit
☆ 1 programmable DC 4-20mA analog output
☆ 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
