Dayton 2 hp brake motor, totally enclosed fan cooled, 145TC frame

Dayton

Dayton 4GPT4 2 hp 1750 RPM 230/460 VAC Brake Motor

SKU CH-E14X-A55A2

Three-phase 2 hp brake motor with washdown enclosure runs at 1750 RPM on 230/460 VAC

  • TypeBrake Motors
  • 2 hp output at 1750 RPM for demanding applications
  • Dual 230/460 VAC voltage suits multiple power supplies
  • 145TC frame fits standard NEMA mounting patterns
  • Totally enclosed fan-cooled design resists washdown environments
  • Continuous duty cycle with 1.15 service factor handles sustained loads

Industrial washdown motor

The Dayton 4GPT4 is a three-phase brake motor rated at 2 hp with a 1750 RPM nameplate speed. It operates on 230/460 VAC and draws 6.0 / 3.0 A at full load. The 145TC frame and totally enclosed fan-cooled enclosure suit washdown environments.

Upgrade from single-speed units

This motor replaces fixed-speed units that lack brake functionality or washdown-rated construction. The jump is worth it when an application demands rapid stopping, continuous duty at 40 Degrees C ambient, and operation on 60/50 Hz supplies. It is not usable at 200 V.

Build integration

The motor fits 145TC mounting patterns and provides CW/CCW rotation flexibility. Class F insulation and a 1.15 service factor handle sustained loads. Usable at 208 V, it frees up voltage selection in facilities with mixed supply. Thermal protection is not included.

Questions about this item

What frame size does the 4GPT4 brake motor use for mounting?

The motor uses a 145TC frame, which sets the bolt pattern and shaft height for NEMA C-face mounting.

How do I wire the dual-voltage motor correctly for 230 V or 460 V three-phase supply?

Follow the nameplate diagram: connect leads for 230 V (6.0 A) or 460 V (3.0 A); the motor is usable at 208 V but not at 200 V.

What brake-component maintenance should I plan for on this washdown-duty brake motor?

Inspect the brake lining and friction surface periodically; replace worn linings and verify the coil resistance to maintain holding torque in wet environments.
