3uF/450V AC Motor Start Capacitor for Reliable Operation
The CBB61 rectangular capacitor ensures efficient starting of electric motors in household and industrial appliances. With a capacitance of 3uF and a rated voltage of 450V AC, the component is quickly installed via its two male terminals and offers P2 SH protection in accordance with European standards. A small investment that extends the lifespan of your electrical equipment.
What you get with this product
- Fast motor start — eliminates hesitation at startup and reduces unnecessary energy consumption
- Wide compatibility — works with air conditioners, refrigeration compressors, water pumps, power tools, and many other pieces of equipment
- Simple installation with male spade terminals — direct connection without soldering or special tools, replacement in under 5 minutes
- Increased reliability with metallized polypropylene dielectric — withstands overvoltages and temperature variations
- Compact rectangular shape — fits into tight spaces where cylindrical capacitors do not
- Guaranteed ±5% tolerance — stable performance throughout the component's lifespan
How it works and how to install it
The capacitor accumulates electrical energy and quickly releases it when the motor starts, providing the necessary torque to overcome initial inertia. Installation is done by connecting the two male spade terminals to the corresponding motor terminals — follow the appliance's wiring diagram or check the existing markings on the old capacitor. Always disconnect the power supply before intervention and discharge the existing capacitor for maximum safety.
Frequently asked questions
How do I know if my capacitor is faulty?
Classic signs: the motor does not start, starts with difficulty, or makes unusual noise. You can test the actual capacitance with a multimeter — if it differs by more than 10% from the nominal value, the capacitor needs to be replaced.
Can I use a capacitor with a larger capacitance?
It is not recommended. Always use the value specified by the motor manufacturer — a different capacitance can overload the windings and reduce the equipment's lifespan.
What does P2 SH protection mean?
P2 indicates the protection class against accidental contact with active components, and SH signifies short-circuit protection through an integrated self-extinguishing device that cuts off the power in case of a fault.
