High-current copper busbar rated at 250 A creates a robust distribution path in compact panel enclosures. This reduces conductor crowding, lowers contact resistance, and minimizes heat buildup, directly improving electrical efficiency and reliability. It’s particularly well-suited for ABB CombiLine modular panels where space efficiency and consistent performance matter for line-side distribution. 945 mm wide, 12 mm high, and 5 mm deep with a 4-section width deliver a compact, scalable footprint. The 0.505 kg weight helps keep cabinet weights manageable during installation and service. The precise dimensions also simplify rack mounting and alignment with standard MBR modules. Suitable for MBR103, MBR203, and MBR303 modules, the 2CPX042536R9999 supports straightforward wiring with 1P continuity. The untreated copper surface allows technicians to tailor finishes or apply protective coatings as needed during or after installation. Its copper enclosure minimizes resistance at connections, ensuring reliable current sharing across adjacent busbars. Regulatory compliance is built-in with CE declarations, RoHS and REACH information, and WEEE classification, simplifying procurement audits and end-of-life planning. DIN 43673-1 alignment and ETIM/eClass classifications help integrators match catalog data. Designed for quick installation, the product supports fast commissioning and predictable maintenance intervals. Its modular nature reduces changeover time when you reconfigure distributions, delivering total cost of ownership benefits for panel builders and OEMs. Thermal performance benefits from the pure copper construction, which provides low resistive losses and better heat dissipation under high current. The flat profile allows efficient busbar stacking and controlled current distribution with minimal hotspots in densely populated cabinets. From a procurement and installation perspective, the 2CPX042536R9999 supports standard ABB panel architecture, reducing the risk of misalignment during assembly. The weight and dimensions simplify handling in mid- to large-scale data centers and industrial facilities, while ETIM and DIN standardization improve data accuracy in BOMs and maintenance schedules.
