CHINT · AC contactor
Product overview
This CHINT NC1-2510/2501 listing is selected by the complete contact arrangement, load duty and coil code. Coordinate the contactor with the appropriate overload relay and protective devices for the circuit.
Technical selection summary
| Listing / model | NC1-2510/2501 |
|---|---|
| AC-3 current reference | 25 A at 380/400 V for the matching three-pole manufacturer row |
| Main / auxiliary contacts | Three main poles for the motor-duty selection; 10: 1NO auxiliary; 01: 1NC auxiliary; match the complete code |
| Control coil | AC coil code and frequency required; Z identifies a separate DC-coil version |
| Load-duty selection | AC-3 and AC-4 currents/powers differ; match operating voltage and switching duty |
| Overload protection | Requires a matched overload relay; the contactor alone is not an overload/short-circuit trip device |
| Manufacturer AC voltage reference | Up to 690 V for the series; use the exact voltage-specific current and utilization-category table |
| Normal installation reference | −5°C to +40°C, altitude up to 2000 m, installation category III and mounting inclination within ±5°; apply the manufacturer correction tables beyond normal conditions |
| Manufacturer standard reference | IEC/EN 60947-4-1; confirm the supplied version and required approval documents |
The catalogue includes several main-contact constructions and AC/DC coil variants. Specify the complete model, coil marking and exact operating duty. Reversing N, DC-coil Z, four-pole 04 and mixed-contact 08 constructions must not be combined by assumption. Current, motor power, lifetime and approval references apply only within their documented version and test conditions.
Typical applications
- Motor control panels with the matching three-pole version
- Replacement procurement with full-code and mounting verification
