- 56-frame steel construction with cradle-base mount
- Continuous duty at up to 40 °C ambient
General-Purpose Split-Phase Motor
The Dayton 5K288 is a 1/2 hp single-phase motor built for continuous-duty HVAC applications. Its split-phase design and 1.25 service factor suit blowers, fans and light industrial equipment running on 230 V AC. The 56 frame and cradle-base mounting fit standard replacement patterns.
Open Drip-Proof Enclosure
The ODP housing allows airflow through the steel frame for cooler operation while resisting vertical drips. CW/CCW rotation is field-selectable, and the keyed shaft secures pulleys or couplings without extra adapters. Class B insulation supports the 40 °C maximum ambient rating.
Cradle-Base Installation
Mounting bolts align with common 56-frame footprints, so most retrofits need only a spanner and basic wiring to the 230 V supply. No thermal protector is fitted; external overload protection must be supplied by the installer. Verify shaft rotation before final tightening to avoid rework.

Questions about this item
Does the motor have thermal protection that would shut it down before winding damage occurs?
The motor lists no thermal protection, so it will not shut itself off if the windings overheat.
What is the first limit reached during continuous operation at full load?
The 1.25 service factor and Class B insulation set the thermal limit; sustained overload will exceed the insulation rating before the service factor margin is used up.
How much noise and heat should I expect when the motor runs all day at 4.6 A?
The open drip-proof enclosure vents heat directly, so the motor surface will reach the 40 °C ambient rating and produce typical split-phase induction noise at 1725 rpm.
