Product Description

Frequently Asked Questions

What is the CBM CBB65 70 MF capacitor used for?

The CBM CBB65 70 MF capacitor is a motor-run capacitor designed for air conditioning and HVAC systems. It provides reliable starting and running torque for AC motors in home appliances such as air-conditioners, air coolers, freezers, and washing machines.

What are the specifications of the CBM 70 MF CBB65 capacitor?

The CBM CBB65 capacitor has a rated capacitance of 70 µF, voltage rating of 370/450 V AC, and uses metalized AL/ZN PP film dielectric with a liquid-filled aluminum case. It features a dissipation factor of Tanδ < 0.002 at 50 Hz and a capacitance tolerance of ±5% or +10%.

Where to buy the CBM 70 MF CBB65 capacitor in Singapore?

You can source the CBM 70 MF CBB65 capacitor through 3G Electric in Singapore. We handle logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time on this CBB65 motor capacitor.

How to select the right CBM CBB65 capacitor for an air conditioner?

Select the CBM CBB65 capacitor by matching the rated capacitance (e.g., 70 µF) and voltage (370/450 V AC) to your compressor or fan motor requirements. Ensure the can dimensions fit your mounting space—for 70 µF, the round can is 50 mm diameter by 125 mm height. Always verify the OEM part number.
