30uF 450VAC Round Motor Run Capacitor

Motor Run Capacitor for AC Motors, Compressors, and Air Conditioners

This 30uF 450VAC round motor run capacitor is designed for start-up and operation support in AC motors running at 50Hz or 60Hz. It is commonly used with air conditioners, compressors, fan motors, pump motors, and other motor-driven equipment that requires a reliable run capacitor.

The CBB65 universal model is built with metallized polypropylene film inside a metal shell, giving it a compact, lightweight design with good heat resistance and anti-explosion protection for safer operation in demanding motor applications.

450VAC Capacitor Replacement for 370VAC Applications

A 440V or 450V rated capacitor can generally be used in place of a 370V capacitor when the capacitance value matches, because the higher voltage rating provides additional margin. However, a 370V capacitor should not be used to replace a 440V or 450V capacitor.

This round capacitor can also be used as a substitute for an oval capacitor as long as the MFD/uF rating and voltage rating match the original part. Always verify the capacitor value, voltage rating, physical size, and terminal style before replacing an existing motor capacitor.

Compact Round CBB65 Capacitor Design

This motor run capacitor uses a round metal case that measures approximately 1.97 inches in diameter by 3.35 inches tall. Its compact size makes it suitable for many HVAC, compressor, and motor repair applications where space is limited.
