Dayton 30PT84 Motor Overview

The Dayton 30PT84 is a 2 hp general-purpose motor rated for 3450 RPM on a 56H frame. It runs on single-phase 115/230 V AC at 60 Hz and draws 17.3 amps at low voltage or 8.7 amps at high voltage. The capacitor-start/run design suits continuous-duty applications where automatic thermal protection is required.

Build Quality and Mounting

An open drip-proof enclosure with insulation class B allows operation up to 40 degrees C ambient. The cradle base and closed-base construction provide stable horizontal mounting, while the 1.15 service factor adds a margin for occasional overload. CW/CCW rotation is selectable to match the driven equipment.

Compatibility Checklist

Verify that your supply voltage matches 115 V or 230 V single-phase and that the starter circuit can deliver the listed full-load amps. Confirm the 56H frame dimensions and shaft height align with the existing mounting pattern. Ensure the driven load does not require inverter-rated operation, as this model is not rated for variable-frequency drives.

Questions about this item

What voltage does the 30PT84 motor run on and what current does it draw at full load?

It operates on 115/230 V AC and draws 17.3 A at 115 V or 8.7 A at 230 V under full load.

What frame size and mounting style does the 30PT84 use?

It uses a 56H frame with a cradle base for horizontal mounting.

How is the 30PT84 wired for rotation and what common mistake should be avoided?

The motor is reversible CW/CCW by swapping the start-winding leads; a common error is changing the run-winding leads instead.
