Schneider Electric ATV71HD18N4 provides closed-loop-capable speed and torque control for demanding three-phase motor applications in the 18.5 kW / 25 hp rating class.
- 18.5 kW / 25 hp rating
- 380-480 V three-phase supply
- IP20 drive execution
- Integrated EMC filter and graphic terminal
The drive is selected from the Altivar 71 N4 range and must be coordinated with the installed motor, upstream protection, braking arrangement, EMC cabling and control option configuration. The nameplate and stored parameter set remain the commissioning baseline.
Important Notice: ATV71HD18N4 is the 18.5 kW N4 IP20 execution. Do not substitute an ATV71W, M3X, higher-power N4 or newer drive family without a complete electrical, mechanical and parameter review.
