Run Capacitor

The run capacitor, which most commonly uses polypropylene film, is a two-terminal electrical device designed to run the entire time the motor is on. The classic CBB61 motor capacitor has a range of 1.5 to 100 microfarads (µF or mfd), with voltage classifications of 370V or 440V.

The motor run capacitor has a hermetically designed structure and is made of epoxy resin and a flame retardant plastic casing. That is why our run motor capacitor has a high insulation resistance, self-healing properties, and protective overload capacity. The motor run capacitor works particularly well for electric fans, exhaust fans, electric water pumps, and electric sewing machines, effectively supporting the starting and running of these machines. Our motor run capacitors are manufactured with high precision machines and come in several models to fit various applications.
