ABB 2CPX041750R9999 Interior fitting module - EN61439-2

Stepless mounting adjustment via the mounting bracket enables precise busbar and terminal alignment, reducing handling errors and rework during cabinet assembly. This streamlines commissioning and accelerates time-to-operational readiness for CombiLine modular distribution panels. The 72 DIN place units within a 300 mm x 750 mm footprint optimize space planning, allowing engineers to allocate room for protection devices, controllers, and metering blocks with predictable layouts, which translates to faster builds and fewer design changes in high-mix environments. With a rated current of 440 A and a short-circuit rating of 20 kA, the module supports robust protection of critical loads in 400 V systems, improving safety margins and system uptime. The center-central busbar position ensures consistent current distribution and heat management, while compatibility with N/PE busbar and terminals and ZX518 busbar holders (busbars ordered separately) enables scalable configurations for future expansion. The enclosure frame options WR or EDF simplify integration into existing installations, reducing retrofit complexity. Material and environmental compliance—RoHS, REACH declarations, CE marking, and WEEE status—support regulatory audits and sustainability goals. All of this is designed to reduce total cost of ownership by minimizing installation effort, optimizing space, and enabling modular expansion for growing control architectures.
