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.
