Wiring torque: Main circuit 1.7N·m, Control circuit 0.5N·m
- Советы по безопасности
Verify voltage after coil power-off to prevent residual voltage
It is recommended to match a thermal overload relay (например, LRD06C) for motor circuits
Derating is required for frequent start-stop scenarios (recommended ≤80% of rated current)
Common Troubleshooting
| Явление неисправности | Возможные причины | Troubleshooting Methods |
| No power to coil | Power circuit break, loose wiring | Measure coil terminal voltage, inspect wires and terminals |
| High noise after pull-in | Contaminated iron core contact surface, broken shading ring | Clean the iron core, replace the shading ring |
| Contact ablation | Перегрузка, incorrect load matching | Check load type, replace contact set |
| Coil burnout | Overvoltage/undervoltage, frequent on-off | Install a surge suppressor, optimize control logic |
Procurement and Maintenance

III. Notes on Replacement Selection
- Совместимость установки: All recommended models are suitable for 35mm DIN rail mounting, with dimensions close to LC1D09BDC (приблизительно. 45мм в ширину), enabling direct replacement of installation positions.
- Wiring Matching: Main circuit wiring torque 1.7N·m, control circuit 0.5N·m, consistent with the original contactor.
- Thermal Relay Matching: It is recommended to match a thermal overload relay below 9A of the same brand (например, ABB TA25DU06, Siemens 3RB2016, Chint NR2-063) to ensure consistent motor protection.
- Surge Protection: It is recommended to install a freewheeling diode or surge suppressor for DC coils to extend service life.
- Снижение номинальных характеристик использования: For frequent start-stop scenarios (>1200 times/hour), derate to below 7.2A for use.
- Quick Selection Suggestions
- Pursue original quality: Select Schneider LC1D09BD
- Prioritize cost performance: Select Chint NXC-09M/22/Z or Delixi CJX2s-0911З
- System compatibility: Select AX09-30-11-80 for ABB systems, 3RT2023-1BB41 for Siemens systems
- Spare part universality: Prioritize mainstream domestic models such as NXC/CJX2s for easier procurement and maintenance
