Copper busbar construction provides low electrical resistance, enabling efficient current transfer even at high loads. The business impact is reduced heat buildup and lower energy losses, contributing to improved overall efficiency and safer panel operation. Application: ideal for CombiLine modular distribution panels where space is tight and high current density is required. Flat 1P design with a 320 A rating delivers compact power paths with minimal interconnections. This reduces contact resistance and simplifies maintenance, extending service life and reliability in MBN169/MBN269/MBN369 configurations. A long 1204 mm length and slim 5 mm thickness with 20 mm height maximize panel width while maintaining thermal performance, supporting near-skin integration within panel rails. The result is faster installation and scalable solutions for growing automation lines. Compliance and material certifications—RoHS, REACH, CMRT, WEEE, and DIN 43673-1—minimize regulatory risk and streamline supplier qualification. Untreated copper surface allows easy inspection, coating compatibility, and cost-efficient field adjustments in electrical rooms or process environments.

FAQs
Plan for the panel width of 1204 mm and the busbar thickness of 5 mm with a 20 mm height, noting that the busbar is supplied as a component not assembled. Ensure compatibility with MBN169/MBN269/MBN369 modules and adherence to DIN 43673-1. Confirm insulation and clearance around the 320 A current path to optimize heat management.
A 320 A rated current provides a robust, low-resistance path for high-load applications, reducing voltage drop and heat generation. This translates to improved efficiency and reliability in modular distribution panels, especially in dense installations and retrofits where current demand is high and space is constrained.
Yes, it is suitable for industrial and process automation environments requiring compliant, high-current copper busbars. It supports MBN169/MBN269/MBN369 configurations and aligns with RoHS, REACH, CMRT, WEEE, and DIN 43673-1 standards, making it appropriate for machine builders and panel manufacturers in regulated markets.
Key certifications include CE Declaration of Conformity for Distribution Panel System CombiLine N, RoHS information and status, REACH declaration, CMRT, WEEE categorization, DIN 43673-1, ETIM 8/9 (EC001522 - Busbar), and eClass V11.0 27370303. These ensure regulatory compliance, supply chain transparency, and consistent product classification.
The untreated copper surface minimizes preprocessing needs while enabling straightforward inspection and coating compatibility. The high-current capability and compact form factor reduce panel complexity and installation time, lowering labor costs and improving return on investment for modular panel projects and retrofit programs.
