SKU CH-8A3R-MJV3E

Single-phase HVAC motor delivering 7/32 hp at 1,200 RPM on 115 V AC with auto thermal protection and continuous duty cycle

  • Delivers 7/32 hp for HVAC airflow
  • Runs at 1200 RPM for steady fan speed
  • Operates on 115 V single-phase power
  • Auto thermal protection prevents overheating
  • Totally enclosed air-over design resists contaminants

Direct OEM Replacement Motor

The Dayton 45909G is a definite-purpose HVAC motor rated at 7/32 hp and 115V AC for continuous-duty air-over applications. It suits technicians and RV owners who need an exact lug-mount replacement for existing equipment.

Simple Lug Mount With Rotation Flexibility

The motor uses a non-standard frame with lug mounting and offers CW/CCW rotation, so orientation can be matched on site. Auto thermal protection and Class A insulation guard against overload, while the 3.4 A full-load rating helps confirm circuit compatibility before wiring.

Verify Voltage And Frequency Before Ordering

This unit is not usable at 208V or 200V and runs on 60/50 Hz single-phase supply only. Check that the nameplate RPM of 1,200 and the 40 °C maximum ambient suit the installation environment, and ensure the existing shaft and lug pattern match the replacement.

Questions about this item

How do I verify the motor is running correctly after installation?

Confirm the shaft rotates freely in either direction, the motor reaches the 1200 RPM nameplate speed, draws about 3.4 A at full load on 115 V, and the automatic thermal protection does not trip during continuous operation within the 40 °C ambient limit.

What comes with the motor and what must I supply separately?

The motor itself is supplied; mounting lugs are integral to the frame. You must provide the 115 V AC single-phase power supply, suitable wiring, a compatible fan or blower wheel for the shaft, and any required capacitors or contactors not built into the motor.

Which voltage version should I choose for a 115 V supply?

This model is rated for 115 V AC only; the specifications state it is not usable at 200 V or 208 V, so select this 115 V version when your supply is 115 V.
