CHINT · DC-coil AC contactor
Product overview
This CHINT NC1-Z listing uses a DC control coil for AC main-circuit switching. Choose the complete frame, auxiliary-contact code and coil voltage, then coordinate the contactor with its overload relay and protective devices.
Technical selection summary
| Listing scope | NC1-1810Z through NC1-5011Z; select the exact intermediate manufacturer model |
|---|---|
| AC-3 current reference | 18, 25, 32, 40 or 50 A at 380/400 V in the matching three-pole DC-operation rows |
| Control coil | 24, 110 or 220 V DC versions in the manufacturer DC-operation table; match the Z coil marking |
| Contacts | Three main poles; match 10 / 01 or 11 auxiliary-contact code to the relevant frame |
| Load duty | AC-3 and AC-4 ratings differ. DC control-coil voltage does not establish DC main-contact switching capability |
| Installation / standard | Match terminals, mounting and overload-relay combination; manufacturer reference IEC/EN 60947-4-1 |
Use the DC-operation table, not the AC-coil table. Main-circuit voltage, utilization category, coil voltage and auxiliary contacts are separate selection fields. Family drawings may show other constructions.
