Complete CHNT AC Contactor Series-Models & رموز النظام

Core Overview

CHNT AC contactors cover 5 main series:

CJX2 (classic), إن إكس سي (Kunlun upgrade), NC1 (industrial IEC), NC2 (high current), NC8 (high voltage heavy duty).

Models are coded by current + اتصالات مساعدة + الجهد اللولبي.

Order codes start with 710010xxxx and cover 6A ~ 1250A.

1. سلسلة CJX2 (Classic, يجري التخلص منها تدريجيا)

طلب: Small-medium motors, 35مم DIN السكك الحديدية, compatible with Schneider LC1-D.

> ملحوظة: 01=1NC, 10=1NO, 11=1NO+1NC. Coil voltages: AC24/36/110/220/380V. Last 3 digits = voltage code.

2. NXC Series (Kunlun Upgrade, السائدة)

طلب: CJX2 replacement, smaller, lower power, حياة أطول.

> ملحوظة: Z = DC coil (على سبيل المثال, NXC-12Z DC24V); M = mechanical latching.

3. NC1 Series (Industrial IEC Standard)

طلب: International standard, موثوقية عالية, frequent operation.

> ملحوظة: NC1-N = reversing contactor. Z = DC coil.

4. NC2 Series (High Current Industrial)

طلب: Heavy motors & main circuits up to 800A.

> ملحوظة: 3P/4P available. Shunt trip, undervoltage release optional.

5. NC8 Series (High Voltage Heavy Duty)

طلب: Up to 1140V, 2650A for metallurgy, التعدين, البحرية.

> ملحوظة: M = mechanical latching. 4P for 3P+N systems. DC coil available.
