Fans D2D146-BG03-14 Schneider AC Centrifugal Fan ATV61/71
AC centrifugal fan cools Schneider ATV61 and ATV71 inverters with 400/480 VAC input and 350 to 560 W power draw
- Wide operating range with dual-voltage 380–480 VAC support
- Compact external-rotor motor fits tight inverter enclosures
- Low-noise forward-curved blades reduce acoustic load
- Speed controllable from 0 to 100 % via analog or serial interface
- Rugged steel-plate construction withstands -25 °C to 60 °C ambient
Schneider ATV61/71 Inverter Cooling
The Schneider D2D146-BG03-14 is an AC centrifugal fan built for ATV61 and ATV71 inverter cooling. It suits industrial maintenance teams and HVAC integrators who need a direct replacement for ebm-papst motor M2D068-GA. The compact external-rotor design fits tight enclosures while delivering forced electronic cooling.
350-560 W Draw at 400-480 VAC
Nominal voltage spans 380 to 480 VAC in star wiring at 50 or 60 Hz. Speed ranges from 2580 to 2960 min-1 with power consumption between 350 and 560 W. Current draw runs 0.6 to 0.78 A. Minimum back pressure reaches 290 to 385 Pa. Operating temperature covers -25 to 60 °C.
Free-Wheeling Backward-Curved Impeller
Backward-curved blades run as a free-wheeling fan without a scroll housing. This saves internal volume and simplifies duct routing in the cabinet. The sturdy steel-plate construction withstands vibration. Speed is fully controllable via analog or serial interface for demand-based airflow up to 35000 m3/h.

Questions about this item
How do I wire the Y-configuration motor for 400 VAC 50 Hz operation?
Connect the three supply phases to the Y-terminal block; the motor draws 0.6 A at 350 W and runs at 2580 rpm under these conditions.
What ongoing maintenance does the sealed external-rotor motor require?
The motor uses sealed bearings; check for abnormal noise or vibration and clean the impeller blades periodically to maintain airflow up to 35000 m³/h.
At what ambient temperature does the fan reach its thermal limit during continuous duty?
The maximum rated ambient temperature is 60 °C; operation above this value will trigger thermal protection and reduce service life.
