HVAC motor for fan accessories
This FASCO D403 motor is a single-phase shaded-pole unit rated at 1/60 HP and 3000 RPM. It operates on 115 V AC at 60 Hz and draws 0.75 A at full load. The 3.3 frame uses a closed-base steel housing with stud mounting.
Sustained-load behaviour
The motor is totally enclosed and rated for a maximum ambient temperature of 40 degrees C. Auto thermal protection and Class B insulation guard against overheating during continuous duty. A service factor of 1 means it delivers its rated output without overload margin.
115 V only — not usable at 200 V or 208 V
The nameplate voltage is 115 V and the specifications explicitly state the motor is not usable at 200 V or 208 V. Buyers wiring for higher voltages must select a different motor.

Questions about this item
How much heat does the 1/60 HP motor add when it runs continuously at 3000 RPM?
The motor draws 0.75 A at 115 V, producing 10 W of output power; the remainder becomes heat inside the totally enclosed steel frame at up to 40 °C ambient.
What mounting hardware must I already have to install the 3.3 frame stud-mount motor?
You need matching stud brackets or a mounting plate drilled for the 3.3 frame stud pattern; the motor itself ships without brackets.
Will the CCWSE rotation and 115 V single-phase supply work with my existing shaded-pole blower wheel?
Yes, if your wheel is designed for CCWSE rotation on a 3.3 frame shaft and operates on 115 V 60 Hz single-phase power.
