Wiring Note

CBB61 run capacitors are non-polarized – either wire can connect to either motor run-winding terminal per the equipment schematic. Always disconnect power before servicing. Verify the original capacitor's µF rating and voltage class before replacement. Match capacitance within ±5% and never substitute a lower voltage rating.

Why Choose This CBB61 Series?

Undersized or degraded run capacitors cause motors to draw excess current, overheat, and fail prematurely. These CBB61 units use self-healing polypropylene film with low ESR and stable capacitance under sustained line-frequency operation, keeping motors cooler, quieter, and more efficient. With 10 popular values from 1.8 to 5µF in stock, you'll have the right drop-in replacement ready for residential and light-commercial fan motors.
