50uF 450V Motor Start Capacitor for Home and Industrial Appliances
This start capacitor is the professional solution for restarting electric motors in air conditioners, compressors, water pumps, and other household or industrial equipment. With a capacitance of 50uF and a rated voltage of 450V, it ensures safe and consistent starts even for high-consumption motors. Complete kit with connection wires, ready for quick installation.
What you get with this product
- Quick restart of faulty motor — replace the worn capacitor and the equipment works immediately, without service costs
- Universal compatibility — works with air conditioner motors, refrigeration compressors, water pumps, fans, and other electric motor appliances
- Connection wires included — direct installation without soldering or additional connectors, saving time and money
- Extended thermal resistance — withstands temperatures between -40°C and +85°C, functional in any season and working conditions
- Guaranteed lifespan — self-healing polypropylene dielectric, tested according to ISO 9001, ensures up to 10,000 hours of operation at 400V
- Certified electrical safety — insulation tested at 2000V AC, protection against short circuits and overvoltages
How it works and how to install
The start capacitor accumulates electrical energy and releases it instantly when the motor starts, providing the necessary impulse to overcome initial inertia. For installation, disconnect the power supply, remove the old capacitor, and connect the wires of the new capacitor to the motor terminals — the brown wire to the phase, the blue wire to the neutral. The operation takes less than 10 minutes and does not require special tools, only a screwdriver. After reconnecting the power, the motor starts immediately.
Frequently asked questions
How do I know if my capacitor is faulty and needs replacement?
If the motor hums when starting, does not start at all, or makes an unusual noise, the capacitor is probably worn out. Also check if it is visibly swollen or burnt.
Can I use this capacitor for any electric motor?
It works with most single-phase motors up to 1.5 kW that require a start capacitor. Check the recommended capacitance and voltage from the motor manufacturer before installation.
What happens if I use a capacitor with a lower voltage than required?
The capacitor can overheat, swell, or even explode. Always use a voltage equal to or higher than that specified by the equipment — this model safely supports 450V.
