Overview
★ It has multiple protection functions such as short circuit, locked rotor, inverse time overload, grounding, phase loss/imbalance, TE time, etc. ★ It monitors the three-phase current, zero sequence current, and three-phase current imbalance of the motor to achieve protection of 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 ★ It has RS-485 communication interface (optical isolation), Modbus RTU communication protocol ★ 4 switch optical isolation inputs, which can achieve external state acquisition function, ★ 3 relay protection control outputs, used for protection trip and fault alarm output functions, etc; ★ Display unit: LCD displays 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;
Product Details
★ 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
★ 4-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;
★ Display unit: LCD displays 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 programmable DC 4-20mA analog output
☆ 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
