NC8 · WIDE-RANGE CONTACTOR
NC8 covers compact motor contactors through very high-current switching.
The 2026 overview lists NC8 working-current coverage from 6 A to 2650 A. Detailed B11 data separates the 06M–1000 motor-control range from 1260–2650 A high-current AC-1 applications.
Verified source data
NC8 is a wide family; the application category changes at the top end.
| Item | NC8 source data | Selection note |
|---|---|---|
| Standards | GB/T 14048.4; IEC/EN 60947-4-1 | Check exact model certification |
| Overview current range | 6–2650 A | Do not assume every size has the same utilization category |
| Motor-control range | NC8-06M to 1000: up to 690 V, AC-3 motor duty | Use AC-3 data for motor switching |
| High-current range | NC8-1260 to 2650: up to 1140 V, AC-1 application stated | Not a direct AC-3 motor-size continuation |
| Overload family | NR8 | NR8 is the primary thermal overload family for NC8 |
