General-Purpose Motor for Machinery

The Dayton 4K812 is a 1 1/2 hp single-phase capacitor-start motor built for continuous-duty machinery applications. It operates on 115/208-230V AC at 60 Hz and delivers a nameplate speed of 1,725 RPM with a 1.15 service factor.

C-Face Rigid Base Mounting

This unit features a 145TC frame with a C-face rigid base for all-angle mounting flexibility. The open drip-proof enclosure requires a clean, dry environment; the motor has no internal thermal protection, so external overload safeguards must be provided by the installer.

Dual-Voltage 115/208-230V Operation

Full-load current draws 19.2 amps at 115V or 9.6 to 10 amps at 208-230V, and the nameplate confirms usability at 208V. Buyers needing a different voltage, a totally enclosed enclosure, or built-in thermal overload protection must select another model.

Questions about this item

How do I verify the motor is running correctly after wiring it to 230 V?

At 230 V the nameplate full-load current is 9.6 A; measure running amps under load and confirm the shaft turns at 725 RPM in either CW or CCW direction.

What ships with the motor and what must I supply separately?

The motor ships as a complete 145TC frame unit with open drip-proof enclosure; you must provide the capacitor, wiring, overload protection and any mounting hardware.

Which voltage setting should I choose for a 208 V supply?

The motor is rated 115/208-230 V and marked usable at 208 V; configure the dual-voltage leads for the 208-230 V connection and expect 10 A full-load current at 208 V.
