Dayton 20CL66 Three-Phase Motor 1/2 HP 48 Frame 230/460V AC

SKU CH-EBAK-A65VW

Three-phase motor delivers 1/2 HP at 3,450 RPM in a 48 frame with 230/460V AC dual-voltage operation

  • 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.
