The CBB60 10+4μF 450V S0 C is a typical "dual-capacity" AC start-run capacitor. It integrates two independent capacitor units within a single housing, specifically designed for driving household or industrial equipment with main and auxiliary motor structures.
Capacity Configuration: 10+4μF Dual Value
The most significant feature of this capacitor is its "10+4" marking. This means it contains both a 10μF and a 4μF storage unit. This design is commonly found in cooling fans or water pumps, where the larger capacity drives the main motor, and the smaller capacity controls the oscillating fan motor or auxiliary pump, achieving integrated control and saving installation space.
Voltage Rating: 450V Wide Application Range
450V represents its maximum AC operating voltage. In 220V civilian circuits, the motor starting moment generates a back electromotive force far exceeding the power supply voltage. The 450V voltage rating ensures that the capacitor will not be damaged by breakdown due to transient voltage fluctuations during frequent starts and stops.
Safety Rating: S0 Fault Protection
S0 is an explosion-proof safety standard for capacitors. It indicates that the product has extremely strong physical stability in its design. Combined with the self-healing properties of its polypropylene film (CBB), even if a minor failure occurs in the internal dielectric, it can automatically isolate the fault point and resume normal operation, preventing open flames or explosions.
Sealing Process: Epoxy Resin Fully Sealed Structure
The fully sealed encapsulation process completely isolates the internal components from the outside air. This structure provides excellent moisture resistance and oxidation resistance. Even when operating for extended periods in kitchen grease (range hoods) or humid environments (water pumps), its insulation resistance remains at a very high level, ensuring no leakage.
Performance Core: Low Loss and Strong Overload Capacity
In actual operation, this capacitor exhibits extremely low energy loss, meaning it generates very little heat when converting energy. At the same time, it has good buffering and overload capacity against the high surge current at the moment of motor startup, ensuring that the motor starts smoothly and maintains a stable speed for a long time.
