- Fonctions principales & Caractéristiques
| Fonction de protection | Technical Description | Mécanisme de fonctionnement |
| Phase Failure Protection | Detects loss of any phase in three-phase power | Upon detection, the relay’s normally closed contact opens, cutting power to the contactor coil |
| Phase Sequence Protection | Identifies phase sequence (normal/reverse) of three-phase power | Once phase sequence is registered, load startup is inhibited if sequence changes; phase failure/reversal LED illuminates |
| Protection contre les surtensions | Protection voltage adjustable from 380V to 460V | Operating time adjustable 1.5s–4s; control circuit opens on overvoltage |
| Protection contre les sous-tensions | Protection voltage adjustable from 300V to 380V | Operating time adjustable 2s–9s; control circuit opens on undervoltage |

- Principe de fonctionnement
The XJ3-D achieves comprehensive protection via internal voltage detection, phase detection, and time-delay circuits:
- Voltage detection: Monitors three-phase voltage amplitude in real time and compares with set over/undervoltage thresholds
- Phase detection: Analyzes phase relationship to judge correct sequence and phase loss
- Logic judgment: Triggers time delay (over/undervoltage) or direct protection (phase failure/reversal) when abnormality is detected
- Protection action: Internal relay operates; normally closed contact opens, cutting power to downstream contactor coil and de-energizing the main circuit
LED Status Indication:
Normal operation: All three LEDs off (faint glow of phase reversal/failure LED under slight unbalance is normal)
Phase failure / reversal: Phase reversal/failure LED on
Surtension: Overvoltage LED on
Sous-tension: Undervoltage LED on
- Câblage & Installation
