Capacitor-Start/Run Motor 1/4 hp

The Dayton 103815.00 is a single-phase general-purpose motor rated at 1/4 hp with a nameplate speed of 1725 RPM. It operates on 115/208-230V AC at 60 Hz and fits a 48 frame with a rigid base mounting. Suitable for continuous duty in machinery and shop equipment.

Open Drip-Proof Enclosure

The open drip-proof design allows airflow for cooling while resisting falling liquids. Insulation Class B and a 1.35 service factor support sustained operation up to a 40°C ambient temperature. Auto thermal protection resets automatically after an overload, reducing unplanned downtime.

Dual-Voltage Wiring and Reversible Rotation

Terminal connections accommodate 115V or 208-230V supply; full-load current is 2.4A at low voltage and 1.2A at high voltage. The shaft rotates CW or CCW by swapping leads, simplifying replacement in existing mounts. Verify frame dimensions and shaft size before installation to ensure mechanical compatibility.

Questions about this item

How often should the capacitors on this 103815.00 motor be inspected or replaced?

The capacitor-start/run design uses internal capacitors that typically last years; plan a visual check during annual maintenance and replace only if the motor struggles to start or hums without turning.

What thermal limit stops this 1/4 hp motor first during continuous operation?

The Class B insulation and 40 °C maximum ambient temperature define the thermal ceiling; running above that ambient or over the 1.35 service factor will trigger the automatic thermal protector.

How much heat and noise should I expect when this motor runs all day at 1725 RPM?

The open drip-proof enclosure vents heat directly, so the frame reaches operating temperature quickly; expect a steady fan-like whir and warm casing, but the auto thermal protection prevents overheating.
