CHINT · AC contactor
Product overview
This CHINT NXC listing covers 6A–630A contactors for switching AC motor circuits. Choose the operating current at the actual main-circuit voltage, then specify the control-coil supply separately. A suitable overload relay is required when the assembly must provide motor overload protection.
Technical selection summary
| Series / listing scope | NXC / 6A–630A |
|---|---|
| Main contacts | 3 normally open main contacts (3P) |
| AC-3 current reference | 6A–630A at 380/400/415 V; ratings at 660/690 V differ |
| Coil selection | AC 24, 36, 110, 220 or 380 V for 6–100 A frames; AC 110, 220 or 380 V for 120–225 A in this listing; 265–630 A uses AC/DC 110–127, 220–240 or 380–415 V ranges. |
| Auxiliary contacts | 1NO + 1NC for 6–100 A frames; 2NO + 2NC for 120–630 A frames |
| Selection standard | IEC/EN 60947-4-1; see the exact frame in the manufacturer catalogue |
| Related four-pole family versions | The manufacturer NXC catalogue also lists separately specified 4P versions in selected frames. For a four-pole requirement, provide the complete 4P model and main-contact form; do not transfer the three-pole motor rating to a different contact arrangement |
The main-circuit voltage is not the coil voltage. A 65 A rating at 400 V does not imply the same motor-duty rating at 690 V.
Typical applications
- Motor starter and pump-control panels
- Machine automation with a matched overload relay
- Replacement contactors selected by frame and coil supply
