Product Description

Frequently Asked Questions

What is the CBM CBB65 40 MF capacitor used for?

The CBM CBB65 40 MF capacitor is a run capacitor designed for motor starting and run applications in air conditioners, air coolers, freezers, washing machines, and other HVAC or industrial cooling equipment. It uses metalized AL/ZN PP film dielectric and a liquid-filled aluminum case for stable, long-life performance.

What are the specifications of the CBM CBB65 40 MF capacitor?

The CBM CBB65 40 MF capacitor has a capacitance of 40 µF, rated voltage of 370/450 VAC, and an oval can type. It operates in a temperature range of 40/70/21, has a dissipation factor tanδ < 0.002 at 50 Hz, and a capacitance tolerance of ±5% or +10%. It includes a mechanical explosion-proof design.

Where to buy the CBM CBB65 40 MF capacitor in Singapore?

You can source the CBM CBB65 40 MF 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 HVAC run capacitor.

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

To select the right CBM CBB65 capacitor, match the capacitance (µF) and voltage rating (VAC) to your motor's requirements. The 40 MF model at 370/450V suits many residential and commercial AC units. Always verify the can type (oval or round) and physical dimensions to ensure proper fit in the equipment.

Common applications for CBM

Industrial boilers — CBM circulation pumps (mod. CM 30W) and solenoid valves (ELV series) for heating-loop control and pump staging.

Burner systems — CBM oil nozzles (FLU atomizer types), electrodes (ELC 200 mm), and solenoid coils (ELV 230V AC) for combustion ignition and flame supervision.

Plant maintenance and retrofit — CBM cable glands (CLI M25), motor couplings (ACC type D), and small-radius fittings (RAC 90°) for equipment reconfiguration and sensor integration.

Boiler water treatment — CBM chlorine test kits (DET free+combined) for feedwater and circulating-water quality monitoring in closed-loop systems.

Pump and motor assembly — CBM couplings, fittings, and cable glands for assembly and rewinding of industrial motors, circulation pumps, and auxiliary equipment.
