ABB 2CPX042249R9999 Busbar System NH-Disconnector - 850 A, 400 V
Part Number: 2CPX042249R9999
Quick Summary
ABB 2CPX042249R9999 is a busbar system module designed to host NH1 fuse disconnectors in panel cabinets. In tight control panels, engineers fight space constraints, wiring complexity, and access issues when expanding protection. The design aligns with DIN EN 61439-3 and 61439-2, carries CE marking, and adheres to RoHS and REACH declarations to support compliance. With a 750 mm by 750 mm footprint, 3P operation, and an 850 A rating, it delivers robust protection for medium-power automation applications. Interior fitting module construction, rail mounting, and 180 DIN places enable fast, safe installation and scalable protection that reduces total cost of ownership.

High current capability enables 850 A at 400 V in a 3P NH1 system. This translates to fewer devices in the cabinet and a smaller overall footprint, lowering material costs and energy losses. The solution is well-suited to mid-range industrial drives and manufacturing lines where space is at a premium. 180 DIN place units and an interior fitting module maximize device density within a 750x750 mm footprint. This design improves protection density while simplifying busbar routing and future upgrades, enabling faster assembly for panel builders using ABB CombiLine busbar systems. Rail mounting WR frame and a 1U height option allow rapid installation and easy retrofits, reducing commissioning time and minimizing cabinet modification risk. The solution is ideal for new builds and upgrades in existing control panels. Eight NH1 fuse switch disconnectors, three poles, and compatibility with 3-pole busbars provide scalable protection. This supports a streamlined protection strategy with consistent maintenance across the panel, suitable for industrial machines requiring modular protection. RoHS, REACH, SCIP, and WEEE compliance simplify audits and procurement, lowering compliance risk and providing clearer supply chain data for electronics procurement in regulated industries.

FAQs
ABB 2CPX042249R9999 is designed as an interior fitting module for the 185 mm NH-disconnector in CombiLine busbar systems. It features a 750x750 mm footprint, 180 DIN place units, and a WR rail mounting frame to simplify installation and future upgrades. For retrofits, verify busbar availability and ensure the maximum current rating of 850 A remains within cabinet limits.
The module supports 400 V nominal operation (maximum 400 V) and an 850 A rated current in a 3P configuration. It accommodates eight NH1 fuse switch disconnectors and uses NH1 fuse size, with six mountable devices total. Knife blade fuse holders are not included, which informs certain protection schemes and future upgrades.
Yes. The 750 mm by 750 mm footprint, 180 DIN place units, and interior fitting module design make it well suited for panel cabinets in manufacturing and process environments. The 3P, 8-fuse architecture supports scalable protection, while the rail-mounted WR frame enables fast installation and straightforward field upgrades, helping to minimize downtime during expansions.
This ABB module complies with DIN EN 61439-3 and DIN EN 61439-2 standards and carries CE marking. It also adheres to RoHS and REACH declarations, SCIP reporting, and WEEE categorization.
