Totaline p257-e5471 Psc Blower Motor 3/4 Hp 4-speed

Product Description

The TOTALINE p257-e5471 is a permanent split capacitor (PSC) direct-drive blower motor built for residential and light commercial air-handling applications. Rated at 1,075 RPM with a multi-horsepower range of 1/5 to 3/4 HP, this single-phase motor operates on 208-230 VAC at 60 Hz. It features four speed taps, reversible rotation, and an open air-over (OPAO) enclosure designed for continuous duty (S1) in air-moving environments. Extended thru bolts and 2.5-inch resilient rings allow base or shell mounting. A licensed HVAC technician typically handles installation in ducted air systems.

This motor is suited for use in forced-air furnace blower assemblies, unit heaters, unit coolers, exhaust fans, and air circulator applications where direct-drive, air-over cooling is appropriate. The 48Y NEMA frame and shell mounting holes support universal replacement of non-ventilated motors across a wide range of equipment configurations. The four-speed tap selection makes it adaptable to varying airflow requirements without swapping the motor.

Key Features

• PSC motor type for reliable, efficient single-phase operation on 208-230 VAC

Compatibility

Designed as an OEM-style direct-drive blower motor replacement compatible with exhaust fans, air circulators, unit heaters, unit coolers, and other air-over applications using a 48Y NEMA frame motor.

Installation Notes

Installation should be performed by a licensed HVAC technician. Disconnect and lock out all electrical power to the air handler or furnace before removing the existing motor. Verify that the replacement motor horsepower tap and rotation direction match system requirements before energizing. Follow applicable NEC guidelines for motor branch-circuit wiring and overcurrent protection.
