FAQs
Begin by verifying panel compatibility with the CombiLine system and the 1024 mm width. Align the busbar with mounting rails or designated connectors, ensuring clean contact surfaces and proper torque on fasteners. Use the single-pole configuration as specified and confirm RoHS-compliant materials for regulatory traceability. Finally, perform a continuity check and insulation test to verify low impedance paths and safe operation under load.
An 850 A rating indicates the maximum continuous current the busbar can carry while maintaining acceptable temperature rise. For panel design, design margins should account for peak loads and ambient conditions. Ensure components downstream (cable sizes, connectors, and protective devices) are sized to match or exceed this current rating to preserve reliability and prevent overheating.
Yes, for environments where regulatory compliance and robust electrical routing are priorities. The copper busbar provides high conductivity, while its conformity with RoHS, REACH, and DIN 43673-1 supports reliable operation in standard industrial panels. For extremely harsh conditions, consider additional enclosure protection or coatings and verify insulation and mounting methods align with your environment and safety standards.
The busbar carries EU Declaration of Conformity, RoHS information and status, REACH declarations, and DIN 43673-1 alignment. Additional classifications include WEEE categorization and ETIM/eClass mappings, which facilitate procurement, cataloging, and cross-system integration across European and global supply chains.
The 850 A rating enables higher current capacity per panel, reducing the need for additional parallel busbar runs. This can lower material and installation time, decrease bare conductor counts, and simplify maintenance with a single, standardized component. Long-term reliability is enhanced through compliant materials and tested performance across thermal cycles, contributing to lower lifecycle costs.
