CBB60 Motor Run Capacitor with 2 Wires Motor capacitor cbb60 sh utilize low-loss metalized polypropylene film for dielectric. The CBB60a motor run capacitors are encapsulated with resin and housed in a self-extinguishing plastic case which allows for superior reliability and a high mechanical shock and vibration strength. The cbb60 sh series of motor run capacitors is ideal for start and run applications in single-phase asynchronous motors and general A.C. applications at industrial frequencies. The cbb60a capacitor is small in bulk, has long life-span and good self-healing characteristic.
