BOJACK 50 uF 370V/450V CBB65 Round run start capacitor Model: CBB65?Universal model? Shell material: Case Material Aluminum, Cover Material Steel Dielectric Material: metallized polypropylene film Capacity: 50 uf Tolerance: ±5% Rated voltage: 370V/450V AC Frequency: 50 / 60Hz Safety rated: 10,000 AFC Capacitor dimension:Diameter<2.165 inch> ?Height <3.937 inch> Operating temperature: -40 ? to +70?/-104?to+158? This capacitor is used for a compressor motor and a fan motor start-up and operation of AC motors with frequency of 50Hz/60Hz such as Industrial Grade Replacement forCentral Air-Conditioners, Heat Pumps, Condenser Fan Motors, and Compressors.It is small in size, lightweight, heat resisting and anti-explosion. Round run capacitor can be used to substitute Oval shape one with the same MFD and volt specs.A 450 volt capacitor can be used in place of a 370 volt, as it is build better, but the 370 can’t be used in place of a 450 volt.
