1/3 hp Capacitor-Start/Run Motor

This Dayton 103813.00 motor delivers 1/3 horsepower for general-purpose machinery applications. It operates on single-phase AC power at 115 or 208-230 volts with a 60 Hz frequency. The 48 frame size and rigid base mounting suit fixed installations. It is built for continuous duty cycles in industrial settings.

Sustained Load Behaviour

The motor carries a 1.35 service factor for handling temporary overloads during continuous operation. Nameplate speed is 1,725 RPM at full load with a 40 degrees C maximum ambient temperature. Insulation class B protects windings during extended runs. No internal thermal protection is fitted, so external overload safeguards are required.

Installation Checks

Verify your supply voltage matches 115V or 208-230V and that the starter capacitor and run capacitor are correctly rated. Confirm the shaft rotates in the needed direction; the motor supports both CW and CCW rotation. Ensure the open drip-proof enclosure suits the environment and that the rigid base aligns with your mounting points.

Questions about this item

How hot does the 48-frame motor get when running continuous duty at 40 °C ambient?

The motor is rated for continuous duty with a maximum ambient temperature of 40 °C and Class B insulation; no thermal protection is built in, so surface temperature will rise with load.

What voltage supply and wiring does the 103813.00 need to operate?

It runs on single-phase 115 V or 208-230 V AC at 60 Hz, drawing 3.8 A at 115 V or 1.9 A at 208-230 V, and requires a rigid base for mounting.

Will the 1/3 hp capacitor-start/run motor align with my existing 48-frame mounting pattern?

Yes, it uses the standard NEMA 48 frame with a rigid base and CW/CCW rotation, matching the bolt pattern and shaft height of other 48-frame motors.
