- Delivers 1/2 HP for three-phase applications
- Dual 230/460V AC input suits varied supplies
- 3,450 RPM nameplate speed drives equipment efficiently
- 4% nominal efficiency reduces energy waste
- 25 service factor handles peak loads reliably
Three-Phase General Purpose Motor
The Dayton 20CL66 is a three-phase general purpose motor rated at 1/2 HP and built in a 48 frame. It operates on dual voltage 230/460V AC at 60/50 Hz and suits industrial equipment requiring continuous duty operation.
Open Drip Proof Enclosure
The open drip proof enclosure provides ventilation while protecting against dripping liquids. Nominal efficiency reaches 73.4 percent at a nameplate speed of 3,450 RPM. Full load current draws 1.8 amps at 230V or 0.90 amps at 460V, and a 1.25 service factor allows temporary overload capacity.
Rigid Base Mounting and Bidirectional Rotation
A rigid steel base secures the motor to mounting surfaces. Ball bearings support the shaft, which rotates clockwise or counterclockwise as wired. Class B insulation and a maximum ambient temperature of 40 degrees Celsius define thermal limits. The motor carries California Proposition 65 warnings for cancer and reproductive harm.

Questions about this item
Will the 1/2 HP three-phase motor run on my existing 230V supply?
Yes, the motor is dual-voltage rated for 230/460V AC and draws 1.8 A at 230V.
How can I verify the motor is performing to spec once installed?
Measure full-load current near 1.8 A at 230V and confirm speed reaches the 3,450 RPM nameplate rating.
Does the 20CL66 come with a mounting base or do I need to buy one separately?
The unit includes a rigid steel base for direct mounting; no separate base is required.
