Schneider LC1D09BDC

Schneider LC1D09BDC is a 3-pole AC-Schütz of the TeSys D series, with a rated current of 9A, a coil voltage of DC24V, 3NO main contacts and 1NO+1NC auxiliary contacts. It is suitable for AC-1/AC-3 loads, supports DIN rail mounting, and is commonly used in industrial automation and motor control.

Kernparameter

Interpretation des Modellcodes

LC1D: 3-pole contactor of TeSys D series

09: Nennstrom 9A

B: DC coil type

D: Coil voltage DC24V

C: Mark for domestic version

Typical Applications and Replacement Selection

1. Anwendungsszenarien: 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-0910Z (DC24V)

Installation and Safety Points

1. Installationsspezifikationen

Ambient temperature: -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

2. Safety Tips

Verify voltage after coil power-off to prevent residual voltage

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

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

III. Notes on Replacement Selection

1. Installationskompatibilität: All recommended models are suitable for 35mm DIN rail mounting, with dimensions close to LC1D09BDC (ca. 45mm in width), 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 (z.B., 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. Derating Use: 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-0911Z
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
