Overview
The GE 5KCP39SGL794 S is a three-quarter horsepower, permanent-split capacitor (PSC) AC motor designed for industrial fan and definite-purpose applications. This single-phase motor operates at 460 volts and delivers rated output at 1075 RPM, making it suitable for continuous-duty cycles in HVAC, manufacturing, and equipment-driven systems. The NEMA 48-frame construction ensures compatibility with standard mounting configurations.
Key Features
- Permanent-Split Capacitor (PSC) design with integrated run capacitor for efficient starting and operation
- Single-phase 460V, 1075 RPM rated for steady-state fan and motor-driven loads
- NEMA 48-frame standard mounting with 1/2-inch diameter shaft
- Low starting current characteristic of PSC design, reducing electrical stress
- Flattened D-shaft configuration (0.464″ × 6.422″) for direct coupling to fans and pumps
- UL and CE certifications for industrial use
