CHINT · Four-pole contactor
Product overview
This CHINT NC1 4P 4NO 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 construction | NC1 4P 4NO |
|---|---|
| Main-contact code | 04: 4 normally open main contacts |
| Frame-code selection | The catalogue lists 09, 12, 25, 40, 50, 65, 80 and 95 frame codes for these four-pole constructions; match the exact code |
| Load rating | Use the rating for the exact four-pole contact arrangement and utilization category; three-pole motor-current figures do not automatically apply |
| Coil selection | Specify the exact AC coil voltage/frequency; confirm a separately documented DC-coil suffix if required |
| 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
- Four-pole switching/control assemblies matched to the contact diagram
- Replacement procurement with full-code and mounting verification
Product reference images and drawings
Match the exact model, coil version, contact construction and dimensions in the reference drawings. Family illustrations may include other frames and do not expand the ordered configuration.
