Feature → Business Impact → Application: The interior fitting module is designed for a 3P NH1 busbar system with 185 mm spacing, maximizing cabinet real estate to 600 mm of usable width and 180 DIN place units. This enables faster wiring layouts and predictable space allocation for future accessories in 900x750x159.5 mm enclosures, ideal for panel builders delivering turnkey distributions. Feature → Business Impact → Application: Six mountable devices and eight NH1 fuse switch disconnectors deliver scalable protection without enclosure redesign, reducing change orders and commissioning time in manufacturing lines. Feature → Business Impact → Application: Rail mounting with WR frames and a 350 mm built‑in depth ensures stable alignment and straightforward retrofits in existing installations, lowering maintenance effort and downtime. Feature → Business Impact → Application: Light grey plastic covers, 90-degree closure, and horizontal busbar alignment improve visibility, safety, and serviceability during routine inspections and fault finding. Feature → Business Impact → Application: Compliance with RoHS, REACH, WEEE category 4 guidance, and CE declarations reduces regulatory risk for international projects while keeping procurement straightforward for OEMs.

FAQs
This interior fitting module is designed for a 185 mm NH-disconnector busbar system with 3P configuration, supports up to 850 A, and fits WR rail mounting in 900 mm by 750 mm cabinets. It also accommodates 180 DIN place units and 6 mountable devices, enabling straightforward integration into ABB CombiLine setups.
Key specs include maximum 400 V operational voltage, 850 A rated current, 3 poles, 8 fuse switch disconnectors, 6 mountable devices, and a built-in depth of 350 mm. The enclosure supports horizontal busbar alignment with a center distance of 185 mm and is suitable for up to 3 copper busbars (busbars ordered separately).
Yes. It holds CE conformity and compliance with DIN EN 61439-3, RoHS and REACH declarations, and is categorized under WEEE 4. Large Equipment. These certifications ensure regulatory alignment, safety, and responsible materials management for global deployments.
The design reduces installation time through plug‑and‑play mounting on WR rails, minimizes wiring errors with clear busbar alignment, and ensures scalable protection with eight NH1 disconnectors. Its durable plastic enclosure and standardized dimensions support predictable maintenance cycles and lower long‑term costs in panel builds.
Ensure horizontal busbar alignment using ZX522 busbar holders and maintain the 185 mm center distance; plan for up to 3 Cu busbars ordered separately. Use the 180 DIN place units within the 600 mm usable width, and mount on the WR rail frame for stable operation compatible with CombiLine configurations.
