Dayton 103843.00 1/2 hp Capacitor-Start/Run Motor

SKU CH-A4G1-4YGYJ

Capacitor-start/run motor delivers 1/2 hp at 450 RPM with 115/208-230V dual-voltage operation and continuous duty rating

  • Product typeElectrical
  • 1/2 hp motor delivers reliable power for general-purpose tasks
  • Capacitor-start/run design provides strong starting torque and efficient running
  • Dual-voltage 115/208-230 V AC suits a wide range of installations
  • Open drip-proof enclosure protects internal components in dry environments
  • Continuous duty cycle with 1.25 service factor handles sustained loads

Motor type and power rating

The Dayton 103843.00 is a single-phase capacitor-start/run general purpose motor rated at 1/2 hp. It operates on 115/208-230V AC at 60 Hz with a nameplate speed of 450 RPM. The 56 frame rigid base mounting suits fixed industrial installations.

Suitable applications and limitations

This motor fits equipment requiring continuous duty at 40 degrees C maximum ambient temperature with manual thermal protection. The 1.25 service factor provides margin for intermittent overloads. Buyers needing higher horsepower, multiple speeds, or automatic thermal reset should consider other motor designs.

Critical voltage compatibility

Full-load current draws 4.4 amps at 115V or 2.4 to 2.2 amps at 208-230V. The motor is usable at 208V. Confirm the supply voltage matches one of these ratings before purchase to avoid damage or failure to start.

Questions about this item

What comes in the box and do I need to buy a capacitor separately?

The motor is a capacitor-start/run design with the capacitor already built in, so no separate capacitor is required; only the motor unit itself is supplied.

Should I choose the 115 V or the 208-230 V connection for my supply?

The nameplate shows dual-voltage 115 / 208-230 V AC; wire the motor for the voltage that matches your branch circuit — 115 V draws 4.4 A, while 208-230 V draws 2.4-2.2 A.

What does the 1/2 hp rating mean once the motor is installed?

At 450 RPM the motor delivers 1/2 hp continuous duty with a 1.25 service factor, so it can handle brief overloads up to about 5/8 hp without tripping the manual thermal protector.
