Product Description

PR-80L power line protection relay is suitable for the protection and monitoring of low-voltage lines with rated voltage below 690V and rated current up to 820A.

PR-80L can monitor on-site signals in real-time and provides system protection against harm to the line caused by faults such as overload, overcurrent, undervoltage, overvoltage, grounding, or leakage. It can realize a variety of operation control functions and also has measurement functions, self-diagnosis, maintenance management, field bus communication, and other functions.

 

PR-80L power line protection relay realizes measurement functions, protection functions, opening and closing control functions, and remote communication functions; it has 10 channels of relay monitoring, can be configured as needed, and supports MODBUS-RTU communication.

 

Feature

  • Ultra-wide range working power supply AC85-265V.
  • Undervoltage, overvoltage and frequency monitoring in AC systems.
  • Digital measured value display via multi-functional LCD.
  • Save the latest 100 trip records.
  • Internal test/reset button, Integrated energy backup.
  • Asymmetry, phase fault, and phase sequence monitoring.
  • Adjustable start-up delay, response delay, and delay on release.
  • The protection functions are complete, and each protection function can realize protection shutdown, alarm or trip.
  • Built-in 4-way relay, which can set to protection mode and measurement and control mode.
  • Programmable analog output function, standard RS-485 communication interface.
  • 96*96mm, Modular design, small size and flexible structure.
