General-purpose single-phase motor
The Baldor-Reliance L3504A is a 1/2 HP capacitor-start/run motor built for continuous duty. It suits light industrial machinery, farm equipment and commercial ventilation where reliable single-phase power is the only supply available.
Thermals noise and power draw
Totally enclosed fan-cooled construction keeps windings within a 40 °C maximum ambient rating while running at 1.25 service factor. Auto thermal protection interrupts the circuit on overload, and the motor draws 3.7 A at full load on 115/230 V 60 Hz supply.
Upgrade path and fit
The 56 frame matches legacy mounting patterns so the unit drops into existing bases without re-drilling. Dual-voltage wiring covers 115 V and 230 V networks and is usable at 208 V, though it cannot operate at 200 V. Shaft rotates CW or CCW for flexible coupling.

Questions about this item
How do I wire the L3504A for 230 V and which step is often missed?
Connect the dual-voltage leads for 230 V as shown on the nameplate diagram and move the internal jumper; the step most people skip is reversing the jumper position after changing the line connections.
What part will need replacement first on this 1/2 HP capacitor-start/run motor?
The start capacitor and centrifugal switch are the wear items; plan to inspect them after several thousand hours of cyclic duty.
At 40 °C ambient with continuous duty, what limit appears first on the L3504A?
The Class B insulation reaches its temperature ceiling before the 1.25 service factor can be used, so the auto thermal protector trips first under sustained overload.
