Us Motors D12C2J4 Psc Ac Motor 1/2 Hp 1725 Rpm

Product Description

The US MOTORS D12C2J4 is a single-phase permanent split capacitor (PSC) AC motor rated at 1/2 horsepower and 1725 RPM. It features an open drip-proof (ODP) enclosure and a rigid mount configuration, making it a standard replacement option for a wide range of residential and light commercial HVAC and equipment applications. The motor runs on a 60 Hz supply and is built on a 48 frame with ball bearings, Class B insulation, and a service factor of 1.25. Licensed HVAC technicians and equipment service pros typically install this motor as a direct drive or belt drive replacement in fans, blowers, and similar rotating equipment.

This motor is suited for residential and light commercial installations where a single-phase PSC motor on a 48 frame is specified. It operates at a single speed with reversible rotation, giving installers flexibility during replacement. The ODP enclosure is appropriate for indoor or sheltered applications where the motor is not exposed to direct water spray or heavy contaminant exposure. The 1/2-inch shaft diameter and 1-1/2-inch shaft length fit standard 48 frame couplings and pulleys commonly found in HVAC blower assemblies and similar equipment.

Installation Notes

Installation should be performed by a qualified technician familiar with rotating electrical equipment. Disconnect and lock out all power to the unit before removing the existing motor or making any wiring connections. Verify that supply voltage, frequency, and rotation direction match the application requirements before energizing. Confirm shaft alignment and mounting hardware torque per the equipment manufacturer's specifications before returning the system to service.
