Product Description

 

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.

 

Feature

• Ultra-wide range working power supply AC85-265V.
• Undervoltage, overvoltage, and frequency monitoring in 3(N)AC systems 0…690 V.
• Digital measured value display via multi-functional LC display.
• Save the latest 100 trip records.
• Internal test/reset button, Integrated energy backup.
• Asymmetry, phase failure, 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 5-way relay, which can be 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.
• Measurement voltage, current, temperature, and frequency signals.
