CHINT · AC contactor
Product overview
This CHINT NXC-18 listing concerns three-pole AC motor switching and remote circuit control. Select the full contact and coil code, then coordinate a suitable overload relay for the motor and starter assembly.
Technical selection summary
| Listing model | NXC-18 |
|---|---|
| AC-3 current reference | 18 A at 380/400 V in the matching 2026 manufacturer selection row |
| Main / auxiliary contacts | 3 main poles; 1NO + 1NC auxiliary contacts |
| Coil selection | AC coil for this frame; select its exact voltage and frequency code |
| Mounting | Screws or 35 mm rail; verify exact outline and terminal clearances |
| Insulation-voltage reference | Ui 690 V for this frame |
| Series operating-voltage boundary | The series reference spans 220–690 V AC; current and motor-power ratings depend on the actual voltage and utilization category |
The 6–630 A family range does not expand this listing to other current frames. Main-contact AC load duty is separate from coil supply. Match AC-3/AC-4 duty, operating voltage, frequency, ambient/altitude derating and the actual coil label. Mini 3P/4P constructions and standard larger frames have different contact arrangements; a reversing /N assembly requires its documented interlock.
Typical applications
- AC motor starter and control panels
- Machine switching with a coordinated overload relay
