Fasco d1055a Psc Motor 1/12 Hp 1375 Rpm 3-speed 115-127V

Product Description

The FASCO d1055a is a permanent split capacitor (PSC) single-phase motor rated at 1/12 HP and 1375 RPM with three selectable speeds. It operates on 115-127 volts at 60 Hz and draws 1.4 amps at full load. Built on a 42 frame with a resilient base mount, this motor is designed for continuous-duty applications in HVAC and refrigeration equipment. The open air over (OAO) enclosure allows airflow across the motor for cooling during operation. Class B insulation and automatic overload protection are standard. UL listed. Licensed HVAC technicians and refrigeration service pros handle typical replacement installs.

The d1055a is suited for residential and light commercial HVAC applications where a compact, multi-speed PSC motor is required. Common install scenarios include evaporator fan assemblies, condenser fan units, and air-handling equipment that call for a 42-frame resilient-base motor. The CWSE (clockwise-shaft-end) rotation is a key selection factor when replacing a failed motor in an existing system. Verify rotation and speed-tap wiring against the original unit before installation.

Key Features

• Three speed taps on 115-127V single-phase, 60 Hz power
• Open air over (OAO) enclosure for airflow-cooled continuous-duty service
• Resilient base mount on a 42 frame for broad equipment fitment
• Automatic overload protection with Class B insulation
• Sleeve bearings and CWSE rotation
• UL listed

Compatibility

Designed as an OEM-style replacement PSC motor for residential and light commercial HVAC and refrigeration equipment requiring a 42-frame, resilient-base, 3-speed motor at 115-127 volts. Listed OEM reference: IEC.

Installation Notes

Installation should be performed by a licensed HVAC or refrigeration technician. Disconnect and lock out all power to the unit before removing the failed motor. Confirm that rotation (CWSE), frame size, mounting style, voltage, and speed-tap configuration match the original motor before energizing. Do not operate the motor outside its rated 104 degrees F maximum ambient temperature.
