2. Промышленная автоматизация: Production lines, конвейеры, фанаты, water pumps and general machinery.
3. Building Electrical: системы отопления, вентиляции и кондиционирования, fire water pumps, elevator auxiliary circuits.
4. Станки: Spindle control for milling machines, drilling machines and small machining centers.
5. Распределение мощности: В сочетании с тепловыми реле перегрузки. (Серия НР2) for complete motor protection starters.
6. Дополнительные примечания
7. Product Upgrade: The NXC KunLun series fully replaces the traditional CJX2 series with improved mechanical structure, electromagnetic performance and expandability.
8. Рекомендации по выбору:

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

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

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

3. Maintenance Tips:

Регулярно проверяйте износ контактов; 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.
