CBB61 5uF 2-Wire 250V 450V AC Ceiling Fan Capacitor

Key Features

  • Model: CBB61
  • Capacitance: 5 uF (microfarads)
  • Tolerance: ±5%
  • Voltage Rating: 250V to 450V AC
  • Frequency: 50/60 Hz
  • Wire Count: 2
  • Maximum Operating Temperature: 70°C
  • Dielectric Material: Metallized Polypropylene Film

Replaces / Cross-Reference Part Numbers

  • Replaces any 2-wire CBB61 capacitor with a 5 uF rating.
  • This 450V AC rated capacitor can safely replace units with lower voltage ratings such as 250V AC or 300V AC.

Compatibility & Fitment

  • Designed for starting and running single-phase motors.
  • Commonly used in ceiling fans, electric fans, range hoods, pumps, and small motors.
  • Fitment depends on physical dimensions. Verify case size to ensure it fits in the available space.

When to Replace

  • Fan blades rotate slowly, even on the highest setting.
  • Fan motor hums but does not start or requires a manual push to begin rotating.
  • One or more fan speed settings no longer function correctly.
  • The original capacitor shows physical signs of failure, such as bulging, cracking, or leaking fluid.

Installation Tips

  • Disconnect all electrical power to the fan at the circuit breaker or fuse box before beginning work.
  • Safely discharge the existing capacitor before handling.
  • Note the wire connections before removing the original part.
  • As a non-polarized capacitor, the two wires can be connected to either circuit wire.
  • The uF (microfarad) rating must match the original capacitor exactly for proper motor operation.

FAQ

If your ceiling fan is struggling to start, hums without spinning, or runs significantly slower than usual, the capacitor is often the culprit. If the fan only starts after being manually pushed or if the speeds are inconsistent, replacing the capacitor is the most effective first step in troubleshooting.
Yes. This capacitor is rated for 250V and 450V AC, making it compatible with systems originally requiring 250V, 300V, 350V, or 400V. As long as the capacitance (5uF) matches your original part, this unit will function correctly within those voltage ranges.
Replacing a CBB61 capacitor is a straightforward repair that typically takes 15 to 30 minutes. You will need a screwdriver to access the fan's switch housing and wire nuts or electrical tape to secure the connections. Always ensure the power to the fan is turned off at the breaker before beginning.
No, the CBB61 2-wire capacitor is non-polarized. You can connect either wire to either lead from the fan motor without affecting performance.
Before installing the new part, inspect the fan motor for any signs of mechanical binding or debris that might prevent it from spinning freely. Additionally, ensure the wire connections inside the housing are clean and tight. If the motor itself is seized or the windings are burnt, a new capacitor will not resolve the issue.
