Features:
- Altivar 71 variable speed drive for an 18.5 kW / 25 hp motor application.
- 380–480 V three-phase supply class with integrated EMC filter.
- Graphic terminal and high-performance flux-vector motor-control capability.
ATV71HD18N4 is the Schneider Electric Altivar 71 variable speed drive for an 18.5 kW / 25 hp motor on a 380–480 V three-phase supply. The reference includes an EMC filter and graphic terminal and supports demanding motor-control applications. Exact replacement depends on the full nameplate, supply, motor, braking arrangement, option cards, communication and controlled parameter file.
Before removal, back up the full drive configuration and record the motor nameplate, line and motor wiring, I/O assignments, communication addresses, feedback hardware, option cards, braking equipment, limits, ramps and interlocks. Do not assume a current Altivar drive is a drop-in replacement; Schneider lists several migration products and kits whose selection requires engineering review. After installation, verify rotation, motor current, speed regulation, stopping, fault handling, interlocks and every affected machine-safety function.
The Schneider Electric ATV71HD18N4 Altivar 71 variable speed drive may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Confirm the complete order identity, hardware execution, receiving-system configuration and required document revision before replacement.
Confirm the 380–480 V three-phase supply, 18.5 kW / 25 hp motor, rated current, overload duty, switching frequency, cable length and motor-control mode before replacement.
Back up the parameter file and record option cards, I/O assignments, fieldbus addresses, encoder or feedback hardware, braking components, ramps, limits and machine interlocks.
Schneider Electric lists current replacement drives and EcoFit options, but they are not asserted as drop-in substitutes. Engineer the power, mounting, wiring, options and parameters, then complete the approved machine commissioning and safety validation.
