How it works and how to install it
The capacitor connects in parallel with the starting winding of the electric motor, creating the phase difference required for starting. Installation involves connecting the 4 spade terminals to the motor terminals according to the wiring diagram, then securing the casing to the support using the included screw. Before installation, disconnect power and discharge the old capacitor by touching the terminals with an insulated tool.
Frequently asked questions
How do I know if the capacitor is faulty?
Common signs include: the motor does not start or starts with difficulty, unusual noise during startup, bulging capacitor casing, or signs of leakage. Testing with a multimeter in capacitance mode confirms the actual value against the nominal 70uF.
Can I use this capacitor for any 450V motor?
Yes, if the motor requires a start capacitor with a capacitance of 70uF. Check the motor label or the original capacitor for the correct values — incorrect capacitance affects performance and can damage the motor.
How often should a start capacitor be replaced?
Lifespan varies: at 450V it guarantees 3000 hours of continuous operation. In normal household use, a capacitor can last 5-10 years, but extreme temperature conditions or voltage fluctuations reduce its lifespan.
