40µF 450VAC Motor Run Capacitor | CBB60 Continuous Duty Capacitor The 40µF 450VAC Motor Run Capacitor is engineered to support the efficient and reliable operation of single-phase electric motors. Designed for continuous-duty applications, this capacitor remains active while the motor is running, helping maintain consistent torque, smoother operation, and improved electrical efficiency. Manufactured using high-quality polypropylene film technology, the CBB60 capacitor provides excellent reliability and long service life in demanding environments. It is commonly used in pumps, compressors, air conditioners, HVAC systems, washing machines, ventilation equipment, and other motor-driven machinery where stable motor performance is essential. A properly functioning run capacitor helps optimise motor efficiency while reducing vibration, electrical stress, and unnecessary wear on motor components. When a run capacitor begins to fail, motors may experience reduced power, overheating, increased energy consumption, or difficulty maintaining speed under load. Featuring a durable cylindrical housing, integrated connection leads, and a secure mounting stud, this capacitor provides a reliable replacement solution for maintenance, repairs, and new equipment installations. Suitable Applications: Water pumps Air compressors Air conditioning systems HVAC equipment Ventilation fans Washing machines Workshop machinery Industrial equipment Commercial motor applications Key Features: 40µF capacitance rating 450VAC voltage rating Continuous-duty motor run capacitor CBB60 polypropylene film construction Supports stable motor operation Improves running efficiency Helps maintain consistent torque Durable cylindrical housing Pre-fitted leads for easy installation Suitable for 50/60Hz applications Common Signs of a Failed Run Capacitor: Reduced motor performance Motor overheating Increased vibration Excessive humming noise Higher power consumption Inconsistent motor speed Browse our full range of Motor Run Capacitors to find the correct replacement for your equipment.
