1/3 hp Capacitor-Start/Run Motor
The Dayton 103838.00 is a single-phase general purpose motor rated at 1/3 hp with a 56C frame. It operates on 115/208-230V AC at 60 Hz and delivers a nameplate speed of 1,725 RPM. The capacitor-start/run design provides reliable starting torque for continuous duty applications. Auto thermal protection and Class B insulation support safe operation up to a 40 Degrees C ambient temperature.
Open Drip Proof C-Face Mounting
This motor suits equipment requiring a rigid base with C-face mounting and reversible CW/CCW rotation. The open drip proof enclosure is not sealed against dust or water ingress, so it is unsuitable for wash-down, outdoor or hazardous locations. Buyers needing a totally enclosed or explosion-proof enclosure should look at a different motor design. The 1.35 service factor allows moderate overload capacity for intermittent demands.
115/208-230V Dual-Voltage Wiring
The motor connects to standard 115V or 208-230V supplies with full-load currents of 3.8A or 1.9A respectively, and is usable at 208V. Wiring for the required voltage frees up circuit capacity on the alternative supply. A 56C frame matches common gear reducers and pump mounts without adapter plates. The 18.75 lb weight allows handling by one person during installation.

Questions about this item
What voltage supply does the 115/208-230V motor require to operate?
The motor runs on single-phase 115 V or 208-230 V AC at 60 Hz; full-load current is 3.8 A at 115 V and 1.9 A at 208-230 V.
Will the 56C frame and 1.35 service factor let it replace an older 56C motor rated for continuous duty?
Yes, the 56C C-face rigid base matches the same mounting pattern, and the 1.35 service factor supports continuous operation at up to 40 °C ambient.
How can I confirm the motor is running at its rated 1,725 RPM after wiring?
Measure shaft speed with a tachometer; under full load it should read approximately 1,725 RPM in either CW or CCW rotation.
