Description
CBB61 Run/Start Capacitor 3 μF 450V (3 uF / 450VAC) with Flexible Wire Leads
Non-polar film run/start capacitor in a rectangular CBB61 series housing with a capacity of 3 μF (3 uF) and a working voltage of 450 VAC is designed for phase shifting and starting single-phase AC asynchronous electric motors. It is manufactured in a rectangular plastic case filled with epoxy resin and equipped with flexible insulated wire leads for quick and convenient installation in confined spaces.
Key Advantages and Features:
- High reliability and self-healing properties: Metallized polypropylene film (MPP) ensures durability and resistance to current overloads.
- Vibration and moisture resistance: The sealed plastic housing with compound filling protects internal components from dust, moisture, and mechanical stress.
- Universal connection: Flexible stranded wires simplify connection in places where soldering or terminal mounting is difficult.
Compatibility and Applications:
CBB61 series 3 μF capacitors are widely used in household and industrial equipment:
- Ventilation and climate control equipment: Floor, desk, and ceiling fans, duct exhaust fans, air conditioning units.
- Pumping equipment: Low-power circulation and drainage pumps.
- Household appliances and power tools: Range hoods, concrete mixers, smokehouses, grinders, and other devices with single-phase motors.

Technician's Tip: If a fan or hood motor hums, rotates weakly, or only starts with a manual push, in 80% of cases, the cause is a loss of capacitance in the run capacitor. When selecting a replacement, focus strictly on the capacitance rating (3 μF) and the housing dimensions to ensure the part fits in its original location.
