Compatibility & Fitment

• Designed for the starting circuit of single-phase AC electric motors.
• Commonly used in applications such as:

When to Replace

• Motor hums but fails to start or starts slowly.
• Circuit breaker trips upon motor startup.
• Visible signs of damage, such as a bulging case, cracks, or fluid leakage.
• Capacitance measures outside the specified tolerance range when tested with a multimeter.

Installation Tips

• Disconnect all electrical power to the unit before performing installation.
• Safely discharge the existing capacitor by shorting the terminals with a resistor or an insulated tool.
• Verify that the µF (MFD) and VAC ratings of the replacement capacitor match the original part.
• AC start capacitors are non-polarized; wires can be connected to either terminal.
• Ensure all electrical connections are secure.
