Centrifugal Fan 1450 rpm 230 V
This centrifugal fan runs at 1450 rpm on 230 V single-phase power. It draws 0.39 A and consumes 135 W. The unit is built for cold-storage and ventilation installations where steady airflow is required.
Thermals noise and power in normal use
At 50 Hz the motor draws 0.39 A and 135 W while producing 105 Pa maximum back pressure. Ambient temperature range spans -40 °C to 40 °C. Impedance protection guards the motor against overload during continuous operation.
Behaviour under sustained load
Starting current reaches 3.0 A at 230 V. When frequency shifts to 60 Hz speed rises to 1690 rpm, power climbs to 185 W and current increases to 0.68 A with 120 Pa back pressure. Thermal overload protectors maintain motor safety throughout extended duty cycles.

Questions about this item
How is the S4D400-AP12-37 wired for 230 V 50 Hz operation, and which connection step is often missed?
Connect the motor in delta across the three phases for 230 V 50 Hz; the step often missed is confirming the nameplate shows delta wiring before applying power.
What maintenance will the centrifugal fan need after extended running at 1450 rpm?
Periodically clean the coated steel blades and braided blade surfaces to prevent dust build-up that reduces airflow and increases motor current.
At 40 °C ambient the motor draws 0.76 A at 50 Hz — what limit appears first during continuous duty?
The thermal overload protector trips once winding temperature exceeds its calibrated threshold, shutting the motor down before insulation damage occurs.
