Genteq 5kcp39ngk311s Psc Motor 1/2 Hp 1120 Rpm 48 Frame

Product Description

The GENTEQ 5kcp39ngk311s is a 1/2 HP permanent split capacitor (PSC) electric motor designed for continuous-duty HVAC blower applications. Rated at 400-460 volts, 50/60 Hz, single-phase, it delivers 1120 RPM across three speeds, making it well suited for air handler and furnace blower assemblies where variable airflow is required. The motor draws 1.6 amps and is built on a 48 frame with an open air-over body, sleeve bearings, and belly band mounting. The shaft measures 6 inches long by 1/2 inch diameter with a flat, and overall motor length is 11.5 inches. Licensed HVAC technicians and refrigeration mechanics are the primary installers for this unit.

This motor is intended for residential and light commercial HVAC systems, specifically in forced-air applications where an open air-over PSC blower motor is specified. The three-speed configuration allows field selection of airflow to match system design requirements. Counter-clockwise rotation must be confirmed against the existing blower assembly before installation. The 48 frame and belly band mounting are standard configurations found across a wide range of air handler and furnace blower housings.

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. Confirm shaft rotation direction, speed tap wiring, and voltage rating match system requirements before energizing. Belly band mounting hardware should be inspected and torqued to the housing manufacturer's specification using the existing mounting band.
