5.2 交換の推奨事項
Current rating mismatch:
Motor power ≤7.5kW: Select LC1N1801 (18あ)
Motor power 15kW: Select LC1N3201 (32あ)
Insufficient auxiliary contacts:
Add LANN series auxiliary contact block, expandable up to 2NO+2NC maximum
異なる制御電圧:
24VDC制御: LC1N2501B5N
380V AC control: LC1N2501Q5N
Higher performance required:
Choose LC1D2501 (TeSys D series), 機械的寿命 10 百万サイクル, 電気的寿命 2 百万サイクル, stronger vibration resistance
Budget limited:
Adopt domestic alternatives such as Chint CJX2-2501, Delixi CJX2S-2501; similar performance with price reduced by about 30-50%
5.3 Application Precautions
- Confirm coil voltage matches control circuit before installation to avoid coil burnout.
- Fasten main circuit wiring with recommended torque 1.85N·m to prevent overheating and poor contact.
- When directly plugging with LRN series thermal relay, ensure complete latch locking to prevent loosening by vibration.
- Reversible control circuit must be equipped with LA9D09978C mechanical interlock to prevent phase-to-phase short circuit.
- It is recommended to parallel surge suppressor at both ends of the coil to protect PLC/relay contacts in control circuit.
- When ambient temperature exceeds 40°C, derate rated current (10% reduction per additional 10°C rise).
- Regularly check contact ablation; replace contactor when main contact wear exceeds 1mm.
