General-purpose capacitor-start motor

The Dayton 3K348 is a single-phase capacitor-start motor rated at 1 hp and 3,450 RPM. It operates on 115/208-230V AC at 60 Hz and fits a 56C frame with a C-face rigid base mounting. The keyed shaft rotates in either direction for flexible installation.

Thermal and electrical characteristics

Continuous duty cycle is supported with a maximum ambient temperature of 40 degrees C and insulation class B. The totally enclosed fan-cooled enclosure provides protection without internal thermal protection. Full-load current draws 13.9 amps at 115V or 6.9-7 amps at 208-230V with a 1.0 service factor.

Replaces comparable single-phase motors

This unit serves as a direct replacement for failed capacitor-start motors in pumps, compressors and conveyors requiring a 56C frame and 1 hp output. The dual-voltage design simplifies wiring changes when moving between 115V and 208-230V supplies. It is not suited for applications needing variable speed, reversible instant start or built-in overload protection.

Questions about this item

How do I wire the 115/208-230V motor for 230 V and which step is often missed?

Move the internal jumpers to the high-voltage diagram on the nameplate and verify rotation before coupling; the step most often missed is re-checking the 6.9 A full-load current after the change.

What maintenance will the 56C frame capacitor-start motor need over time?

The sealed bearings are lubricated for life, so only periodic cleaning of the totally enclosed fan-cooled vents and a visual check of the starting capacitor are required.

Which limit appears first when the 1 hp motor runs continuously at 3450 RPM in 40 °C ambient?

The Class B insulation reaches its temperature ceiling first because the motor has no thermal protection and a 1.0 service factor.
