The MPR-6M Multifunction Protection Relay is suitable for circuit protection and monitoring of electrical lines and distribution cabinets. It can monitor various parameters in real time, such as current, voltage, power, and electric energy. It is particularly ideal for safety protection of critical power supply lines, fire power distribution, industrial power cabinets, computer rooms, and intelligent building power distribution systems.

The device has a built-in Class 0.2 high-precision measurement unit, with standard 2-way DO output, 2-way DI input (expandable to 4-way), 4-way temperature sensors, and 2-way residual current monitoring. It supports multiple protection action modes including overcurrent, overvoltage, and undervoltage. Via RS485 communication, it can upload data to SCADA, EMS, and smart operation and maintenance platforms. It also features functions like sound and light alarm, remote control, and automatic tripping.
