5.2 Recomandări de înlocuire

Current rating mismatch:

Motor power ≤7.5kW: Select LC1N1801 (18O)

Motor power 15kW: Select LC1N3201 (32O)

Insufficient auxiliary contacts:

Add LANN series auxiliary contact block, expandable up to 2NO+2NC maximum

Different control voltage:

24V DC control: LC1N2501B5N

380V AC control: LC1N2501Q5N

Higher performance required:

Choose LC1D2501 (TeSys D series), mechanical life 10 milioane de cicluri, viata electrica 2 milioane de cicluri, 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.
