Model Code Interpretation

LC1D: 3-pole contactor of TeSys D series

09: Rated current 9A

Б: DC coil type

Д: Coil voltage DC24V

С: Mark for domestic version

Typical Applications and Replacement Selection

  1. Сценарии применения: Suitable for start-stop control of squirrel-cage motors with current ≤9A, as well as control of AC-3/AC-1 loads such as heating equipment, fans and water pumps. It is compatible with DC control circuits of PLC and DCS systems.
  2. Replacement Selection

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

Cross-brand replacement: ABB A16-30-01 (DC24V), Siemens 3RT2015-1BB41 (DC24V), Chint NXC-0910З (DC24V)

Installation and Safety Points

  1. Installation Specifications

Температура окружающей среды: -5℃~+40℃, Altitude ≤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

  1. 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 неисправностиВозможные причиныTroubleshooting Methods
No power to coilPower circuit break, loose wiringMeasure coil terminal voltage, inspect wires and terminals
High noise after pull-inContaminated iron core contact surface, broken shading ringClean the iron core, replace the shading ring
Contact ablationПерегрузка, incorrect load matchingCheck load type, replace contact set
Coil burnoutOvervoltage/undervoltage, frequent on-offInstall a surge suppressor, optimize control logic

Procurement and Maintenance

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

Гарантийный срок: 18 месяцы, It is recommended to inspect contact wear and wiring tightness quarterly

The following are the mainstream cross-brand direct replacement models for Schneider LC1D09BDC (3-столб, 9А, DC24V, 3NO main contacts, 1NO+1NC auxiliary contacts), classified by brand with core parameter matching marked for quick selection and replacement.

  1. Key Points for Core Parameter Matching

Ensure the following key parameters are consistent during replacement:

Pole number: 3-столб

Номинальный ток: 9А (at AC-3 400V)

Coil voltage: DC24V (округ Колумбия)

Main contacts: 3НЕТ (3 нормально открытый)

Auxiliary contacts: 1НО+1НЗ (1 нормально открытый + 1 нормально закрытый)

Service category: AC-1/AC-3 (suitable for resistive loads and squirrel-cage motors)

III. Notes on Replacement Selection

  1. 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.
  2. Wiring Matching: Main circuit wiring torque 1.7N·m, control circuit 0.5N·m, consistent with the original contactor.
  3. 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.
  4. Surge Protection: It is recommended to install a freewheeling diode or surge suppressor for DC coils to extend service life.
  5. Снижение номинальных характеристик использования: For frequent start-stop scenarios (>1200 times/hour), derate to below 7.2A for use.
  6. Quick Selection Suggestions
  7. Pursue original quality: Select Schneider LC1D09BD
  8. Prioritize cost performance: Select Chint NXC-09M/22/Z or Delixi CJX2s-0911З
  9. System compatibility: Select AX09-30-11-80 for ABB systems, 3RT2023-1BB41 for Siemens systems
  10. Spare part universality: Prioritize mainstream domestic models such as NXC/CJX2s for easier procurement and maintenance
