40 uF/MFD/Microfarad 450 VAC Volts CBB60 50Hz/60Hz

Key Features

  • Model: CBB60
  • Capacitance: 40 Microfarad (µF)
  • Voltage Rating: 450 VAC
  • Frequency: 50Hz / 60Hz
  • Capacitance Tolerance: ±5%
  • Operating Temperature: -40°C to +85°C
  • Termination: 2 wire leads
  • Construction: Metallized polypropylene film in a cylinder-shaped housing

Replaces / Cross-Reference Part Numbers

  • Replaces any CBB60 run capacitor with matching capacitance and voltage specifications.
  • Verify that the µF value (40) and VAC rating (450 or lower) match the original part.

Compatibility & Fitment

  • For starting and continuous operation of single-phase AC motors.
  • Suitable for applications including water pumps, washing machines, air conditioners, fans, and various electric motors.

When to Replace

  • Motor fails to start, hums, or is slow to reach operating speed.
  • Motor overheats or runs intermittently.
  • Visible damage to the existing capacitor, such as bulging, swelling, or leaks.

Installation Tips

  • Disconnect all electrical power to the equipment before installation.
  • Safely discharge the old capacitor by shorting the terminals with an insulated tool.
  • The replacement capacitor's voltage rating must be equal to or greater than the original.
  • This is a non-polarized capacitor; wires can be connected to either terminal.
  • Ensure the physical dimensions are suitable for the mounting location.

FAQ

This CBB60 run capacitor features a rated capacity of 40uF with a tolerance of ±5%. It is rated for 450V AC and operates at both 50Hz and 60Hz. The physical dimensions are 94mm in length and 45mm in diameter.
Common signs of a failing capacitor include the motor struggling to start, humming loudly without turning, or the equipment losing power during operation. If the capacitor casing appears swollen, burnt, or shows signs of leaking fluid, it should be replaced immediately.
You can generally use a capacitor with a higher voltage rating than the original (e.g., replacing a 250V with a 450V), but you should never use one with a lower voltage rating. The capacitance (uF) must match the original specification to ensure the motor runs at the correct torque and speed.
You will typically need a screwdriver to access the capacitor housing and a pair of insulated needle-nose pliers to disconnect and reconnect the terminals. Ensure you have a multimeter capable of measuring capacitance to verify the new part if necessary.
Always disconnect the power supply to the equipment before beginning work. Because capacitors store an electrical charge even after the power is cut, you must discharge the old capacitor by bridging the terminals with an insulated screwdriver before handling the wires.
Run capacitors are often subjected to heat stress, voltage spikes, and normal wear over time. Operating the motor in high-ambient-temperature environments or allowing the motor to run while restricted by debris can accelerate the degradation of the internal components.
