Applicazioni tipiche

1. Controllo motorio: Frequent start/stop/reverse of 3-phase asynchronous motors (ca. 30kW@400V).
2. Automazione industriale: Production lines, trasportatori, tifosi, water pumps and general machinery.
3. Building Electrical: Sistemi HVAC, fire water pumps, elevator auxiliary circuits.
4. Macchine utensili: Spindle control for milling machines, drilling machines and small machining centers.
5. Distribuzione dell'energia: Combinato con relè termici (Serie NR2) for complete motor protection starters.
6. Note supplementari
7. Product Upgrade: The NXC KunLun series fully replaces the traditional CJX2 series with improved mechanical structure, electromagnetic performance and expandability.
8. Linee guida per la selezione:

Select current rating according to motor power (65A matches approx. 30kW motor).

Confirm coil voltage (220V / 380V most common).

Expand auxiliary contacts via AX series modules if signal points are insufficient.

3. Suggerimenti per la manutenzione:

Regularly check contact wear; replace contacts when excessive contact resistance occurs.

Keep the contactor clean from dust and moisture.

Apply periodic energization (1–2 times monthly) for long-term idle equipment to prevent coil dampness.

7. Selezione & Guida alla sostituzione
8. Series Selection

New project: Adopt NXC KunLun series as priority.

Intelligent control: Choose NC5NE intelligent contactor.

Compact cabinet: Use ultra-thin NXCF.

Compensazione della potenza reattiva: Special NXCC capacitor contactor.

2. Current Selection

Rated current ≥ motor rated current × 1.1 (normal duty).

Frequent operation ≥ motor current × 1.25.

3. Tensione della bobina

Match control circuit voltage: AC220V / AC380V most common; safety low-voltage 24V/36V optional.

4. Contatti ausiliari

Expandable via external auxiliary blocks when signal points are insufficient.

Reversing circuit must adopt mechanical interlock type.
