PR600 Power Line Protection Relay is designed to protect and monitor low-voltage lines with a rated voltage below 690V and a rated current of up to 820A. This line protection device offers real-time monitoring of on-site signals and protects against faults such as overload, overcurrent, undervoltage, overvoltage, grounding, or leakage. It can perform various operation control functions, including measurement functions, self-diagnosis, maintenance management, and Fieldbus communication, among others.
The low-voltage line protector incorporates measurement functions, protection functions, opening and closing control functions, and remote communication functions. It features 10 channels of switching value monitoring that can be configured as per requirements and supports MODBUS-RTU communication bus for seamless integration into existing systems.
