Dayton 1/3 hp Capacitor-Start/Run Motor

The Dayton 103834.00 is a single-phase general purpose motor rated at 1/3 hp with a nameplate speed of 1,725 RPM. It operates on 115/208-230V AC at 60 Hz and draws 3.8 amps at 115V or 1.9 amps at 208-230V. The 56 frame rigid base design suits fixed industrial installations.

Open Drip Proof Enclosure Limits

The open drip proof enclosure allows airflow for cooling but only protects against dripping liquids at angles up to 15 degrees from vertical. It is not suitable for wet, dusty or outdoor environments without additional shielding. Maximum ambient temperature is 40 degrees C and insulation class B defines the thermal limit.

Upgrading from Split-Phase or Smaller Frame Motors

This capacitor-start/run design delivers higher starting torque and better running efficiency than basic split-phase motors of the same power rating. The 1.35 service factor provides a margin for occasional overloads. Buyers needing reversible rotation, continuous duty at 208V or a rigid 56 frame mounting will find the jump worthwhile.

Questions about this item

Should I choose the 115 V or the 208-230 V wiring for the Dayton 103834.00?

The motor is dual-voltage; at 115 V it draws 3.8 A, while at 208-230 V it draws 1.9 A, so pick the voltage that matches your supply.

What does the 1/3 hp rating deliver on the shaft of this motor?

At full load the shaft turns at 1,725 RPM with a 1.35 service factor, giving continuous duty at 40 °C ambient.

How does the 56 frame and open drip-proof enclosure affect installation?

The NEMA 56 frame sets the bolt pattern and shaft height, and the open drip-proof design requires a clean, dry mounting location.
