The **Chint XJ3-D** is a phase failure and phase sequence protection relay designed for three-phase AC circuits (380V). It actively monitors electrical systems to prevent equipment damage caused by:
- **Phase loss/failure** (e.g., blown fuses or broken wires)
- **Voltage fluctuations** (overvoltage/undervoltage)
- **Incorrect phase sequencing** (critical for irreversible motors like pumps)
Upon detecting faults, it instantly cuts power to the main circuit’s contactor coil, isolating the load for protection . Its DIN rail-mountable design suits industrial control panels, offering reliability in harsh environments .
