DIN 43673-1
The 2CPX042579R9999 copper busbar delivers a robust 250 A rated current, enabling a single conductor path to carry main feeders in CombiLine modular distribution panels. This reduces the need for multiple parallel bars and simplifies wiring, leading to faster assembly and a smaller panel footprint. Its physical profile is purposefully compact, with a height of 12 mm, a width of 527 mm, and a depth of 5 mm, which supports tighter enclosure spacing and easier feeder routing in control cabinets and switchgear. The untreated copper surface keeps initial material costs low while allowing integration with standard connectors and terminal blocks, with room for later surface treatment if required. Compliance and traceability are baked in through RoHS, REACH, CMRT, and DIN 43673-1 alignment, supporting regulatory approvals and safer end‑of‑life handling. Weight is 0.281 kg per unit, aiding logistics and field‑installation planning, and packaging is pack 1 piece for straightforward stock management. Overall, the design delivers reliable current handling, reduced installation time, lower total cost of ownership, and scalable performance for evolving automation layouts.

FAQs
Yes. The 2CPX042579R9999 copper busbar is designed for ABB CombiLine modular distribution panels and uses a standard flat busbar profile. It fits 1P configurations with a 527 mm width section and 12 mm height. For mounting, align with compatible terminal blocks and connectors and secure with standard fasteners recommended for copper busbars in CombiLine enclosures.
Rated current is 250 A, suitable for main feeders in compact panel layouts. As a copper busbar with an untreated surface, it provides low impedance paths that help minimize voltage drop under steady load. Short-term surge handling depends on system design and protective devices; ensure coordination with breakers and protective relays to maintain safe operation within the 250 A rating.
Industries with space‑constrained automation and power distribution needs benefit most: automotive robotics panels, process control cabinets, and machine builders deploying CombiLine modular panels. The 527 mm width and 12 mm height fit narrow enclosures, while 250 A capacity supports central feeders in switchgear and motor control centers.
Key standards include CE declarations of conformity for distribution panel systems, RoHS compliance with EU Directive 2011/65/EU and 2015/863 amendments, REACH declarations, and DIN 43673-1 for busbar components. WEEE categorization is 4 for large equipment. These ensure regulatory alignment, safer disposal, and traceability for procurement and audits.
Using a 250 A copper busbar reduces the number of parallel conductors, simplifying maintenance and lowering assembly time. The lightweight 0.281 kg per unit and compact dimensions minimize shipping and logistics costs while enabling faster panel builds. Long-term reliability combined with RoHS/REACH compliance reduces compliance risk and rework during audits.
