C65
Faratronic C65 (CBB65) explosion-proof aluminum AC motor capacitor, 4 uF to 100 uF, 250 to 450 Vac, for compressor duty.
The C65 from Faratronic is a cylindrical aluminum-case AC motor capacitor, known in the market as the CBB65, with an explosion-proof design for compressors and larger single-phase motors. It uses metallized polypropylene film with self-healing behaviour and stable capacitance, and the aluminum cylinder gives a rugged part with good heat transfer and a long life, built to the GB/T3667.1 standard equivalent to IEC 60252-1. The series covers roughly 4 uF to 100 uF at 250 Vac to 450 Vac for 50 Hz or 60 Hz operation, which fits refrigeration and air-conditioning compressors, larger pumps and motors that carry a higher continuous current than a fan motor. The anti-explosion case adds a pressure-disconnect mechanism: if the internal pressure rises, the case deforms and opens the connection, so the capacitor fails safe rather than venting or bursting, which is why the style is preferred where a fault must not damage the equipment. The metal case also handles the vibration of a compressor better than a plastic box. These capacitors are used in air conditioners, refrigerators, heat pumps and industrial pumps. Every part BeiLuo ships is factory-traceable and includes an import declaration, a certificate of origin and a RoHS compliance file, and mainstream values are held in stock.
FAE Professional Review
The C65 is the explosion-proof CBB65 cylinder for compressor duty. The pressure-disconnect case is the reason to choose it over a box capacitor in refrigeration and air conditioning, where a failed capacitor must not damage the compressor. Match the value to the motor and check the terminal type.

Frequently Asked Questions
What is the C65 rated for?
The C65 (CBB65) covers about 4 uF to 100 uF at 250 Vac to 450 Vac for 50 or 60 Hz operation, in a cylindrical aluminum case with an explosion-proof design, built to IEC 60252-1.
Match the capacitance to the compressor requirement.
What does explosion-proof mean for a capacitor?
The case has a pressure-disconnect mechanism: if the internal pressure rises at end of life, the top deforms and opens the connection, so the capacitor fails safe instead of venting or bursting. That is why the style is used where a fault must not damage the equipment.
It is a safety feature, not just a case style.
Is the C65 genuine and in stock?
BeiLuo supplies factory-traceable C65 capacitors through Faratronic official channels, with import declaration, certificate of origin and RoHS files on every order. Mainstream values are normally in stock.
