3UF 450VAC Capacitor – CBB61 Motor Run Capacitor

3UF 450VAC Capacitor for Fans & AC Motors

The 3UF 450VAC capacitor is a CBB61 motor run capacitor designed for compatible electric fan motors, appliances and other AC motor applications. It has a 3.0µF capacitance, ±5% tolerance and a 450VAC rated voltage, making it a practical replacement where these specifications match the original capacitor.

Motor run capacitors form part of the electrical system of compatible AC motors and are used to support the motor’s intended operation. The CBB61 format is commonly used in applications such as electric fans and other motor-driven appliances.

When replacing an existing capacitor, always compare the original component’s capacitance and voltage rating with the replacement before installation.

Key Features

3.0µF Capacitance

The 3UF 450VAC capacitor provides a capacitance value of 3.0µF. Capacitance is one of the most important specifications to check when selecting a replacement motor capacitor.

The stated ±5% tolerance indicates the permitted variation around the nominal 3.0µF value.

For a replacement, match the capacitance required by the original motor or appliance rather than selecting a capacitor based only on its physical size or appearance.

450VAC Motor Run Capacitor

This CBB61 capacitor has a 450VAC rated voltage, making it suitable for compatible AC motor applications designed to use this voltage rating.

The voltage rating and capacitance should both be checked against the original capacitor and the equipment manufacturer’s specifications before installation.

Suitable for Compatible Fan Motors

CBB61 motor run capacitors are commonly used in electric fan and similar AC motor applications. The 3UF 450VAC capacitor can be considered when servicing compatible equipment requiring these exact electrical specifications.

Common applications include:

• Electric fan motors
• Compatible household appliances
• AC motor applications
• Fan repair projects
• Motor maintenance
• Electrical repair work
• DIY appliance repairs
• Replacement capacitor applications

How to Choose the Correct Replacement

When replacing a motor run capacitor, check the specifications printed on the existing capacitor or those provided by the equipment manufacturer.

For this product, the main specifications are:

• 3.0µF / 3UF capacitance
• ±5% tolerance
• 450VAC rated voltage
• CBB61 motor run capacitor

Matching these specifications helps you select an appropriate replacement for compatible equipment.
