Get SupportWhat is the function of the XJ3 Protection Relay?
It protects three-phase systems from phase loss, incorrect phase sequence, overvoltage, undervoltage, and voltage imbalance, ensuring stable and safe equipment operation.
What is the difference between XJ3-G, XJ3-G1, and XJ3-D models?
XJ3-G: Includes imbalance protection (8–13%) along with open-phase and phase sequence detection.
XJ3-G1: Detects only open-phase and phase sequence faults.
XJ3-D: Adds overvoltage and undervoltage protection functions.
What voltage can the XJ3 relay handle?
All models operate at AC 380V with a ±10% fluctuation tolerance, suitable for standard industrial control systems.
How fast does the relay respond to a fault?
Response time is ≤0.1s for phase failure or sequence errors, providing quick protection for motors and circuits.
What is the installation method?
The XJ3 series can be mounted on a 35mm DIN rail or fixed by soleplate, depending on the model.
