Detailed description

Designed to optimize electrical connections in demanding marine installations, the BEP 779-LB-2-B medium busbar is a key component of the Pro Installer system. This device enables the creation of robust and organized connections between fuse holders or other compatible electrical elements.

Integration and performance

The BEP 779-LB-2-B busbar is specifically sized to connect components with a spacing of 35.5 to 42.5 mm, accepting studs with a diameter of 8 to 10 mm. It can handle a continuous current of 650A at a maximum voltage of 50V DC, making it suitable for 12V, 24V, and 48V systems. This capacity positions it as a solution for high-power circuits, offering a structured alternative to conventional jumper cables.

Robust and modular design

Manufactured with tinned copper conductors (CDA102), known for their conductivity and corrosion resistance, and base materials in high-temperature-resistant fiberglass, this busbar ensures durability in marine environments. The studs, washers, and nuts in stainless steel prevent seizing and improve the longevity of the installation. Its design aligns with the modularity of the BEP Pro Installer system, ensuring a common interconnection height for easy integration with other BEP products. The transparent protective covers, equipped with removable side skirts, provide three-sided insulation and flexibility for cable entry.

« BEP Pro Installer busbar: robustness and power circuit integration »

The medium BEP 779-LB-2-B busbar is an essential component for structuring and securing high-power marine electrical installations. Its primary function is to consolidate connections between heavy-duty fuse holders or other distribution elements, typically in main circuits or for demanding consumers.

In an installation scenario, it is often used to connect two fuse holders or a fuse holder to a main busbar, ensuring stable current distribution and minimizing losses. The advantage of this busbar lies in its integration with the BEP Pro Installer system, enabling compact and professional arrangement in electrical panels or engine compartments.

This product differs from simple jumper cables by its ability to maintain precise and standardized spacing between components, which is crucial for consistency and compatibility within the BEP Pro Installer system. The materials used, such as tinned copper, along with its 650A capacity, make it suitable for critical applications where reliability and high-current management are paramount.

It is important to note that this busbar is specifically designed for spacings of 35.5 to 42.5mm and studs of 8 to 10mm. Therefore, it is essential to verify compatibility with existing fuse holders or terminal blocks. It is not intended for low-ampacity connections, where its cost and size would be oversized for the application. Its maximum benefit lies in the organized and secure management of high currents.
