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 (24 В постоянного тока), Siemens 3RT2015-1BB41 (24 В постоянного тока), Chint NXC-0910З (24 В постоянного тока)

Installation and Safety Points

1. Характеристики установки

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

2. 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)

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. Защита от перенапряжения: 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. Рекомендации по быстрому выбору
7. Pursue original quality: Select Schneider LC1D09BD
8. Prioritize cost performance: Select Chint NXC-09M/22/Z or Delixi CJX2s-0911З
9. Совместимость системы: 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
