CBB61 4.5uF+5uF+6uF 4-Wire 250V AC Ceiling Fan Capacitor

Key Features

  • Model: CBB61
  • Capacitance: 4.5uF, 5uF, 6uF
  • Number of Wires: 4
  • Rated Voltage: 250V AC
  • Frequency: 50/60Hz
  • Tolerance: ±5%
  • Maximum Operating Temperature: 70°C
  • Construction: Metallized polypropylene film with a plastic shell
  • Function: Starts and regulates speed in single-phase motors

Replaces / Cross-Reference Part Numbers

  • Replaces any CBB61 capacitor with the same capacitance, voltage, and wire configuration. Check your original part for a direct match.

Compatibility & Fitment

  • Designed for 3-speed ceiling fans requiring a 4-wire capacitor with 4.5uF, 5uF, and 6uF values.
  • Can be used in other applications with single-phase motors, such as pumps or small industrial motors, that match these electrical specifications.
  • Verify physical dimensions and mounting specifications to ensure proper fit within the device housing.

When to Replace

  • Ceiling fan operates at a single speed or will not change speeds.
  • Fan blades rotate slowly or require a manual push to start.
  • Motor produces a humming sound but does not engage.
  • 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 main circuit breaker before servicing.
  • Carefully note or photograph the wiring configuration of the original capacitor before removal.
  • Safely discharge the old capacitor by shorting its terminals with an insulated tool.
  • Match each new wire to its corresponding connection from the original unit.
  • Ensure all connections are secure before restoring power.

FAQ

A failing capacitor is the most common cause of ceiling fan issues. You likely need a replacement if your fan is slow to start, hums but won't spin, or if the fan speeds are no longer changing correctly when you adjust the wall or pull-chain switch.
This unit features a 4-wire configuration with a common wire (typically gray) and three separate capacitance leads: Red (4.5uF), Brown (5uF), and Purple (6uF). Ensure you match these colors to your existing wiring harness during installation.
It is critical to match the uF ratings exactly to your original capacitor. Using a capacitor with different capacitance values can cause the fan motor to overheat, run at incorrect speeds, or fail to start entirely.
Replacing the capacitor is a straightforward repair that typically takes 15 to 30 minutes. You will need a screwdriver to access the fan housing and wire nuts to secure the connections. Always turn off the power at the circuit breaker before beginning work.
CBB61 capacitors are subject to heat stress and electrical wear during normal operation. Over several years, the internal dielectric material degrades, leading to a loss of capacitance. This is a standard maintenance item for most ceiling fans.
Before installing the new part, inspect the fan's motor for any signs of physical obstruction or debris that might prevent it from spinning. Additionally, ensure the wire connections are tight and free of corrosion, as loose connections can mimic the symptoms of a bad capacitor.
