CBB80 45uf 250v 85℃ Vde Line With Fuse, With Resistance, With Screw

The CBB80 series is a high power factor compensation capacitor, utilizing high-quality polypropylene film technology and specifically designed for reactive power compensation in high-power gas discharge lamps (such as sodium lamps and metal halide lamps). This model integrates a fuse and a bleeder resistor, along with a temperature-resistant housing and bolt-mount design, ensuring stable circuit power factor while providing an extremely high operational safety margin. It is a key component in lighting engineering and industrial power environments.

Core Technical Specifications and Characteristics
Electrical Energy Storage and Withstand Voltage: Rated capacity is 45μF, operating voltage is 250V. Its internal structure employs a non-inductive winding process, significantly reducing internal losses and maintaining a low temperature rise even under continuous high load operation.

Multiple Safety Protection Mechanisms
Built-in Fuse: Quickly disconnects the circuit in case of abnormal current fluctuations or internal capacitor failure, preventing escalation of the accident.
Built-in Resistor: Automatically discharges residual voltage, ensuring the safety of maintenance personnel after power failure, and complies with stringent international safety certifications such as VDE.

Materials and Packaging Process
Utilizing a high-temperature resistant polypropylene film with self-healing properties, it automatically recovers its function even in the event of minor insulation breakdown. The outer shell undergoes an anodized brightening treatment, providing excellent oxidation resistance and physical protection. A screw-on base ensures adaptability to various vibration and vertical installation environments.

Environmental Adaptability
The specified operating temperature is 85℃, with an actual environmental tolerance range of -40℃ to 105℃, capable of withstanding extreme climates or high-temperature heat buildup inside enclosed lighting fixtures.

Application Areas
This component is ideal for industrial lighting systems, primarily used in:

Power supply systems for high-pressure sodium lamps, mercury lamps, and metal halide lamps.

Current regulation for inductive loads, significantly optimizing grid efficiency.

Operating Environment Requirements
Altitude Limitation: Recommended for operation in areas below 3000m altitude to ensure effective heat dissipation and insulation clearance.

Residual Voltage Management: Before commissioning, the system residual voltage must be reduced to below 10% of the rated value to prevent voltage superposition from impacting components.

Media Purification: The installation area should be kept dry and clean, and contact with conductive dust, corrosive gases, and flammable and explosive substances is strictly prohibited.
