Standards
DIN 43673-1
Copper busbar, 30 mm x 1083 mm x 10 mm, rated to 630 A, provides a low-resistance current path that supports high-load applications in modular panels. This feature translates to lower thermal rise, improved efficiency, and the ability to carry sustained currents in compact ABB CombiLine installations. The Flat model 1P design enables straightforward alignment within 1083 mm wide panel sections, reducing assembly time and installation risk for panel builders. The untinted untreated copper surface keeps initial costs down while allowing compatibility with customer-specific finishes or protective coatings in controlled environments. Compliance elements such as CE, RoHS, REACH, and DIN 43673-1 help ensure regulatory alignment across markets and simplify supplier qualification in audits. With a net weight of 2.447 kg and a pack weight of 2.545 kg, it supports predictable logistics and handling. The product's integration within the CombiLine ecosystem minimizes compatibility concerns and accelerates project delivery in modular switchgear environments.

FAQs
This busbar is designed to fit within ABB CombiLine modular panels with a width of 1083 mm and 1P configuration. Confirm panel slot alignment, mount the copper busbar to the busbar carrier, and connect the conductors to the adjacent terminals. The Flat model simplifies orientation and reduces assembly time, while its 30 mm height keeps cabinet stacking minimal. Always follow ABB installation guides and ensure proper torque on connection points to maintain low resistance paths.
The busbar is rated for 630 A and configured as 1P (one pole). This specification supports high-current distribution in modular panels while maintaining compact dimensions suitable for space-constrained switchgear environments. For applications requiring higher current, consider parallel paths or alternative panel configurations within the CombiLine family.
Yes. The 2CPX042981R9999 copper busbar is designed for CombiLine modular distribution panels and control cabinets used in manufacturing and utilities. Its dimensions and current rating are optimized for compact assemblies, enabling efficient current distribution in busy production lines and automated systems without compromising reliability or service life.
The busbar comes with CE conformity, RoHS information and status, REACH declarations, and DIN 43673-1 standards. It also references EU declarations of conformity and WEEE handling classifications, ensuring regulatory compliance and traceability across European markets and audit processes.
With an untreated copper surface, plan for appropriate surface protection in the final assembly to prevent oxidation where exposure is possible. The high-conductivity copper path reduces resistive losses, contributing to energy efficiency and potential lifecycle cost savings. The component’s compact footprint and interoperability within CombiLine panels support faster installation, reducing labor costs and time-to‑service for modular power distribution projects.
