Regal Beloit c621 Capacitor Start Resilient Base Motor 1.5 Hp 1725 Rpm 115 208-230V Single Phase 56 Frame

Product Description

The Regal Beloit C621 is a capacitor start, resilient base electric motor rated at 1.5 HP and 1725 RPM. It is built for single-phase power and accepts voltage input of 115V or 208-230V at 60 Hz. The motor fits a 56 frame configuration, which is a standard NEMA frame size widely used in HVAC equipment, pumps, compressors, and general industrial machinery. HVAC technicians, mechanical contractors, and equipment repair professionals rely on motors like the C621 to power blowers, fans, and other rotating equipment in commercial and residential systems. The drip-proof (DP) enclosure protects internal components from falling debris and moisture drips, making it suitable for indoor mechanical rooms and light-duty exposed environments. The resilient base mount reduces vibration transfer to the equipment frame, which helps lower noise levels and extends the service life of connected components. Capacitor start motors deliver high starting torque, which is important when driving loads that require extra force to get moving, such as compressors, loaded conveyors, or pumps. The single-phase design makes this motor compatible with standard residential and light commercial electrical service without the need for a three-phase supply. At 41 pounds, the C621 is a robust unit built for durability in demanding field conditions. Technicians replacing failed motors in older HVAC or pump systems will find the 56 frame and standard voltage ratings make cross-referencing and drop-in replacement straightforward. The C621 has been discontinued by the manufacturer and is replaced by the 5KCR49SN0150X (C1160) once existing inventory is depleted. Stock on hand is available for immediate service and repair needs.
