1/3 hp Capacitor-Start/Run Motor
The Dayton 103816.00 is a single-phase, general-purpose motor rated at 1/3 horsepower. It suits equipment requiring continuous duty in a 48 frame size with rigid base mounting.
115/208-230 V AC 60 Hz supply limits
This motor operates on 115 V or 208-230 V AC at 60 Hz, drawing 3.8 A at the lower voltage and 1.9 A at the higher voltages. Its 1.35 service factor provides a modest overload margin, while the Class B insulation and 40 °C maximum ambient temperature define the thermal envelope for sustained operation.
Rigid base mount with reversible rotation
The open drip-proof enclosure and closed base design allow straightforward rigid-base installation. Automatic thermal protection resets without user intervention. Wiring for clockwise or counter-clockwise rotation must be set correctly at the terminal box; incorrect connections are the most common cause of reversed shaft direction.

Questions about this item
Should I choose the 115 V or the 208-230 V wiring for this 1/3 hp motor?
Wire it for the supply you have; the nameplate shows 3.8 A at 115 V and 1.9 A at 208-230 V, and the motor is usable at 208 V.
What does the 1725 RPM rating mean when the motor is under load?
1725 RPM is the nameplate speed at full load on 60 Hz power; with the 1.35 service factor it can handle short overloads without dropping far below that speed.
How does the 48 frame and rigid base affect installation?
The NEMA 48 frame sets the bolt pattern and shaft height, and the rigid base means you bolt the motor directly to a flat mounting surface.
