Cambridge 45+7.5μF ± 5% 440/370 VAC dual round run start AC capacitor Capacitor Dimensions: W: 1.97 in / 50 mm x L: 1.97 in / 50 mm x H: 3.94 in / 100 mm Operating Temperature: -40℃ to +70℃ / -40℉ to +158℉; Safety rated: 10,000 AFC Compliant with US Standards UL 810 and IEC 60252-1:2001 and tested 100% electrical Heavy-edge metalized pp film with aluminum case makes it durable, reliable, resistant to corrosion Cambridge dual round run capacitors for AC are used for start-up and operation of both single-phase and three-phase AC motors with a frequency of 50Hz/60Hz, such as central air-conditioners, heat pumps, condenser fan motors, compressors, and other electric motor-driven systems. Engineered for superior durability and precision, Cambridge dual round run capacitors ensure optimal motor performance and longevity for your equipment’s motor life. Constructed of high-grade dielectric materials and robust aluminum outer casing, Cambridge air conditioner capacitors are known for their ability to handle continuous duty cycles without overheating, ensuring the engines run smoothly and efficiently. The capacitors feature labeled spade terminals such as "C" (Common), "HERM" (Hermetic), and "FAN" (Fan), making them easy to connect and install with no special tools required. The capacitors come in various capacitance ratings tailored to different motor sizes and applications. Capacitors should be installed by licensed professionals. Cambridge uses the highest quality materials and manufacturing procedures to ensure the products we supply to the HVAC industry over the last 75+ years are top-rated and can be trusted. Our HVAC capacitors are UL810 and IEC 60252-1:2001 tested and certified, rated with a one-year warranty.
