Rated at 1\/4 horsepower and 115 volts, it operates at 1075 RPM nameplate speed with a 48YZ frame and yoke mount configuration. The open air-over (OAO) enclosure allows airflow across the motor for cooling, making it well suited to indoor blower and fan assemblies. Ball bearings support the shaft, and automatic thermal protection guards against overheating. A 1\/2-inch diameter shaft extends 3-3\/4 inches for direct coupling to fan wheels or blower assemblies. Licensed HVAC technicians and motor replacement specialists are the primary installers.\u003c\/p\u003e\u003cp\u003eThis motor is applied in residential and light commercial HVAC systems where a yoke-mount, OAO-enclosure PSC motor is required. Typical install scenarios include indoor air handler blower decks, evaporator coil fan assemblies, and similar forced-air equipment that uses a 48YZ-frame motor. It runs at two speeds, supports counterclockwise rotation from the lead end, and is rated for ambient operating temperatures down to 40 degrees F. The Dayton cross-reference part number is 4UX60, which aids in identifying compatible equipment and verifying drop-in fitment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/4 HP single-phase PSC motor rated at 115 volts, 60 Hz\u003c\/li\u003e\n\u003cli\u003e1075 nameplate RPM with two-speed operation\u003c\/li\u003e\n\u003cli\u003e48YZ frame with yoke mount for direct replacement in HVAC blower decks\u003c\/li\u003e\n\u003cli\u003eOAO enclosure designed for air-over cooling in fan and blower applications\u003c\/li\u003e\n\u003cli\u003eBall bearing construction for extended service life\u003c\/li\u003e\n\u003cli\u003eAutomatic thermal protection with Class B insulation\u003c\/li\u003e\n\u003cli\u003eCounterclockwise rotation from the lead end; 1\/2-inch x 3-3\/4-inch shaft\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OAO yoke-mount PSC replacement motor for 48YZ-frame HVAC blower and fan applications.

Disconnect and lock out all electrical power to the unit before removing the existing motor. Verify shaft diameter, rotation direction, and mounting configuration match the original motor before installation.
