PR600 Power Line Protection Relay

PR600 Power Line Protection Relay

PR600 Power Line protection relay is suitable for low-voltage line protection and monitoring with rated voltage below 690V in 3(N)AC systems. and rated current up to 820A. This series of products monitors 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, etc. It can realize a variety of operation control functions and also has measurement capabilities. , self-diagnosis, maintenance management, fieldbus communication and other functions.

PR600 Power Line protection relay can realize measurement function, protection function, opening and closing control function and remote communication function; it has 10 channels of switching value monitoring, which can be configured as needed, and supports MODBUS-RTU communication bus.
