Input/Output Terminals: Used for connecting current sensors, voltage sensors, and relay outputs.
Enclosure: Made of metal or high-strength plastic, with dustproof and waterproof properties.

Typical Application Fields

Protection for main and backup power supplies in power plants and substations
Protection for distribution network lines, transformers, and busbars
Comprehensive protection for power distribution systems in industrial parks and buildings
Smart grid projects requiring remote monitoring and automated control

Installation and Maintenance Points

Installation Location: It should be placed in a cabinet or dedicated protective box with good ventilation, no strong magnetic fields, and no direct exposure to high temperatures.
Wiring Specifications: Follow the ABB standard wiring diagram to ensure correct connection between current sensors, voltage sensors, and the protection relay, avoiding incorrect wiring.
Communication Configuration: Configure the IP address, subnet mask, and gateway in the on-site network to ensure normal Modbus/BACnet communication.
Regular Inspection: Conduct inspections every 6 months to check the integrity of the enclosure, the tightness of wiring, and the stability of power supply. Update the firmware if necessary to obtain the latest protection algorithms.
Fault Diagnosis: Use the built-in self-test function and remote monitoring platform to view fault logs, quickly locate and resolve abnormalities.
