Industrial centrifugal fan for inverter cooling
The Ebm-Papst R3G355-RB03-10 is a backward-curved centrifugal fan driven by an EC motor rated at 230 VAC. It delivers 1350 RPM while drawing 2.0 A and consuming 205 W. The 355 mm impeller uses six PP plastic blades and ball-bearing construction. An IP54 enclosure and insulation class B allow operation from -25 °C to 50 °C.
Suits maintenance on ABB ACS800 drives
Engineers replacing a failed unit in an existing inverter cabinet will match the original airflow and mounting pattern. Buyers who need a different voltage range, higher static pressure or a forward-curved impeller should look elsewhere. The single-intake design also limits use in ducted dual-inlet configurations.
Verify supply voltage.
Confirm the site provides 200–240 VAC at 50/60 Hz and that the 355 mm diameter fits the cut-out. Check that the 3.7 kg weight is supported by the existing brackets. Ensure the IP54 rating satisfies the enclosure's environmental specification before ordering.

Questions about this item
What power supply must already be available for the 230VAC 2.0A fan to run?
A single-phase 230VAC supply rated for at least 2.0A continuous current within the 200–240VAC range at 50/60Hz.
Can the 355mm backward centrifugal impeller be mounted in the same duct as an older 280mm axial fan without airflow conflict?
The 355mm backward curved wheel produces a different pressure curve; match duct static pressure to the fan's 205W operating point rather than relying on the old fan's profile.
How do I confirm the IP54 ball-bearing unit is delivering its rated 1350RPM after installation?
Measure the motor current at 2.0A and verify rotational speed with a tachometer reading 1350RPM under normal ambient conditions.
