Replacement Selection

Intra-series replacement: LC1D09BD (imported version with identical parameters)

Cross-brand replacement: ABB A16-30-01 (CC 24 V), Siemens 3RT2015-1BB41 (CC 24 V), Chint NXC-0910z (CC 24 V)

Installation and Safety Points

Especificaciones de instalación

Ambient temperature: -5℃~+40℃, Altitud ≤2000m, Avoid dust/corrosion/condensation

Reserve heat dissipation clearance, spacing between adjacent devices ≥5mm

Wiring torque: Main circuit 1.7N·m, Control circuit 0.5N·m

Safety Tips

Verify voltage after coil power-off to prevent residual voltage

It is recommended to match a thermal overload relay (p.ej., LRD06C) for motor circuits

Derating is required for frequent start-stop scenarios (recommended ≤80% of rated current)

Common Troubleshooting

Fenómeno de falla	Posibles causas	Métodos de solución de problemas
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
ablación por contacto	Sobrecarga, 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

Order Number: LC1D09BDC, Packaging: 1 pc/box, 21 pcs/carton

Período de garantía: 18 meses, It is recommended to inspect contact wear and wiring tightness quarterly

III. Notes on Replacement Selection

Installation Compatibility: All recommended models are suitable for 35mm DIN rail mounting, with dimensions close to LC1D09BDC (aprox. 45mm in width), 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 (p.ej., 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.
Derating Use: 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-0911z
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
