General-purpose motor for HVAC systems
The Dayton 30PT52 is a single-phase capacitor-start/run motor rated at 1/3 hp and 3450 RPM. It operates on 115/230V AC at 60 Hz with a 48Z frame and cradle-base mounting. The open drip-proof enclosure suits indoor HVAC equipment where airflow is unrestricted. Continuous duty and auto thermal protection support long-running fan or blower applications.
Installers needing a direct-drive replacement
This motor fits HVAC units that specify a 48Z frame, horizontal mounting and clockwise or counter-clockwise rotation. It is not for inverter-fed drives, high-ambient environments above 40 °C or applications requiring a totally enclosed enclosure. Builders needing multi-speed operation or a different shaft configuration should look at other models.
1/3 hp output with 1.35 service factor
At full load the motor draws 3.7 A at 115 V or 1.8 A at 230 V, delivering rated torque for typical residential and light-commercial blowers. The 1.35 service factor provides headroom for brief overloads such as dirty-filter conditions. Continuous operation beyond nameplate amperage or in ambients exceeding 40 °C will trip the thermal protector and reduce service life.

Questions about this item
What voltage supply and frame size must my installation provide for the 30PT52 motor?
The motor runs on 115/230 V AC and fits a 48Z frame, so your mounting cradle and wiring must match those specifications.
Will the 3450 RPM speed and 1/3 hp output work with my existing 60 Hz single-phase HVAC system?
Yes, the motor is rated for 60 Hz single-phase operation at 3450 RPM and 1/3 hp, matching standard residential HVAC power.
How can I verify the motor is running correctly after wiring it to the cradle base?
Confirm the shaft rotates freely in either direction, the nameplate shows 3450 RPM at full load, and current draw stays near 3.7 A on 115 V or 1.8 A on 230 V.
