Replaces / Cross-Reference Part Numbers

  • Direct replacement for any CBB60 capacitor with matching specifications.
  • Interchangeable with other run capacitors rated at 25 uF and 450V AC.

Compatibility & Fitment

  • Designed for starting and running single-phase AC motors.
  • Common applications include water pumps, pressure washers, air compressors, HVAC systems, fans, and washing machines.
  • Verify physical dimensions of the original capacitor to ensure proper fit.

When to Replace

  • Motor hums but struggles to start or fails to start.
  • Reduced motor power or performance.
  • Motor overheats during operation.
  • Capacitor case is visibly bulging, cracked, or leaking oil.
  • Capacitance measures outside the specified tolerance range when tested.

Installation Tips

  • Disconnect all electrical power to the appliance before installation.
  • Safely discharge the existing capacitor by shorting the terminals with an insulated-handle screwdriver.
  • Note the wire placement on the old capacitor terminals before disconnecting.
  • Confirm that the voltage (VAC) and microfarad (uF) ratings match the original part.
  • Securely mount the new capacitor using the M8 screw and attach wire connections firmly.

FAQ

A failing capacitor often presents as a motor that hums but fails to start, runs slower than usual, or lacks its typical power. If you notice your pump or motor overheating, struggling to reach full speed, or if the capacitor itself shows signs of physical damage—such as bulging, leaking, or a burnt smell—it is time for a replacement.
You can safely use this 450VAC capacitor in applications that originally called for a lower voltage rating (such as 250VAC or 370VAC), as the higher rating provides a greater safety margin. However, you must match the capacitance (25 uF) exactly. Never replace a capacitor with one that has a lower voltage rating than the original.
This 25 uF capacitor is designed for single-phase AC motors operating at 50/60Hz. It is commonly used in water pumps, air conditioning units, compressors, washing machines, and various electric motor-driven appliances.
No, this is a non-polarized capacitor. It can be connected in either direction within the circuit without affecting performance.
Installation is straightforward and typically takes 10 to 20 minutes. You will need a screwdriver to secure the mounting bolt and a pair of insulated pliers or a wire stripper for the terminal connections. Always ensure the power is disconnected and the old capacitor is fully discharged before touching the terminals.
The most common causes of failure are age, excessive heat exposure, and voltage spikes. Over time, the internal dielectric material degrades, causing the capacitor to lose its ability to hold a charge, which prevents the motor from maintaining the necessary phase shift to run efficiently.
