Industrial centrifugal fan for drive cooling

The RB4C-355/170 K 9201 9207RH3 is a galvanised-steel centrifugal fan built for AC230/400 V three-phase supply. It targets engineers maintaining ACS800 drive cabinets or similar industrial enclosures where a direct-replacement impeller and motor assembly is required. The IP44-rated motor and included mounting plate simplify swap-in installation without fabricating new brackets.

Capacitor and plate eliminate separate sourcing

A run capacitor and pre-drilled mounting plate ship with the unit, so the installer does not need to order ancillary parts or drill new holes. This reduces downtime during planned maintenance or emergency replacement of a failed drive-cooling fan. The assembly arrives ready to bolt onto the existing cut-out and connect to the drive's auxiliary supply.

355 mm impeller at 1400/1600 min⁻¹

The 355 mm diameter impeller delivers rated speeds of 1400 min⁻¹ at 50 Hz and 1600 min⁻¹ at 60 Hz, drawing 1.2/1.3 A and 170/235 W respectively. This airflow envelope is the decisive figure; if the drive cabinet's thermal design calls for a different pressure-flow curve, the fan will not meet the cooling requirement.

Domande su questo articolo

How often should the IP44-rated motor bearings be inspected or replaced on the RB4C-355/170 K?

The IP44 motor protection helps resist dust and splashes, but bearing life depends on load and ambient temperature. Plan a visual and noise check at each scheduled shutdown; replace if rumble or excess play appears.

What thermal limit triggers first when the fan runs continuously at 170 W input power?

At 170 W input the motor winding temperature rise reaches its class limit before the impeller or capacitor. The built-in thermal protector will cut power if the winding exceeds its safe threshold.

What noise and heat levels should I expect when this 355 mm impeller runs all day at 1400 min-1 on 230 V?

At 1400 min-1 the fan moves significant airflow; expect a steady broadband hum typical of metal centrifugal impellers and motor surface temperatures that can exceed 60 °C in free air.
