ABB 2CPX042257R9999 Busbar System - 3P 850A DIN EN 61439-3

Interior fitting module for the 185 mm NH‑disconnector busbar system provides a ready footprint that accelerates installation in CombiLine distribution panels. By aligning busbars horizontally and supporting up to 12 mountable devices, it reduces field wiring errors and commissioning time, enabling faster project delivery. This module uses a 750x750 mm enclosure with 180 DIN place units and a usable width of 600 mm, and it is unequipped for NH1–NH3 until you install the devices, providing design flexibility for future configurations. Rail mounting with WR enclosure frame delivers secure, tool‑free device swaps and scalable expansion. This design simplifies audits and maintenance, helping you reconfigure the panel as your system evolves without replacing the entire enclosure. Compatibility with 180 DIN place units and the 750 mm by 750 mm footprint delivers high-density distribution in compact cabinets. The 850 A rated current capacity supports demanding loads while leaving room for future growth. Materials and closures—plastic covers, light grey color, and a 90‑degree press and turn closure—offer durability and a clean finish while meeting corrosive and environment requirements in standard industrial settings. The design also uses ZX522 busbar holders for secure, reliable busbar support. Compliance and lifecycle benefits—RoHS and REACH declarations, a CE conformity status, and DIN EN 61439 compliance help you pass regulatory reviews and minimize risk. With the ability to order 12 mountable devices and insert NH1‑NH3 devices, the module minimizes obsolescence and supports long‑term maintenance budgets.
