3.5uF 450V Motor Start Capacitor for Home and Industrial Appliances
This rectangular CBB61 capacitor ensures reliable starting for electric motors in appliances such as air conditioners, fans, water pumps, and compressors. With a rated voltage of 450V AC and connection via 4 male terminals, it serves as a direct replacement solution for single-phase motors in domestic, commercial, or industrial applications.
What you get with this product
- Instantaneous start of single-phase electric motors, eliminating hesitation or noise at startup
- Universal compatibility with various appliances: air conditioners, water pumps, refrigerator compressors, fans
- Quick connection via 4 male terminals, without the need for soldering or modifications to the installation
- Durable plastic casing protects internal components and ensures safe electrical insulation
- High durability due to metallized polypropylene dielectric film, resistant to temperature and humidity
- Compact rectangular dimensions allow easy installation even in narrow spaces within appliances
How it works and how to install
The capacitor stores electrical energy and releases it quickly when the motor starts, providing the necessary torque to overcome initial inertia. Installation is performed by connecting the 4 male terminals to the corresponding motor terminals, following the electrical diagram of the appliance. Replacing a faulty capacitor requires disconnecting the power supply, dismounting the old capacitor, and connecting the new capacitor to the same terminals, an operation that takes less than 10 minutes.
Frequently asked questions
How do I know if the motor capacitor is faulty?
Common signs include: the motor does not start at all, starts with difficulty with excessive noise or vibration, or operates intermittently. In these cases, replacing the capacitor usually solves the problem.
Can I use this capacitor for any electric motor?
The capacitor is compatible with single-phase motors that require a capacity of 3.5uF and an operating voltage of up to 450V AC. Check the specifications of the original capacitor before replacement.
Is it safe to install it myself or do I need an electrician?
If you have basic electrical knowledge and follow the power disconnection procedure, installation is simple. For maximum safety, it is recommended to consult a qualified technician.
