This interior fitting module is designed for a 185 mm NH-disconnector busbar system and supports a three-pole configuration. Business impact: Enables precise busbar alignment and secure mounting on a rail system, reducing miswiring risk and simplifying maintenance. Application: Ideal for CombiLine panels in industrial automation and electrical distribution, where space is tight and future expansion is anticipated. With 60 DIN place units, the enclosure offers scalable capacity for growing control architectures. Business impact: Allows device additions without rework, cutting commissioning time and downtime. Application: Fits modular distribution cabinets up to a 275 mm built-in depth, with horizontal busbar alignment and ZX522 holders. Rated current up to 850 A and 400 V maximum voltage make it suitable for main distribution or local panels, ensuring reliability under peak loads. Built-in depth of 275 mm and a 250 mm width support compact, serviceable layouts. The enclosure uses plastic covers in light grey (RAL 7035) and includes an WR mounting frame for straightforward installation on a DIN rail. Compliance and certifications—CE declarations, DIN EN 61439-3/2, RoHS, and REACH—reduce regulatory risk while supporting WEEE and SCIP requirements. This modular approach aligns with ABB CombiLine busbar systems, enabling faster assembly, easier upgrades, and consistent protection across control and power circuits.

FAQs
This interior fitting module is engineered for the 185 mm NH-disconnector busbar system and accommodates a 3-pole configuration within ABB CombiLine panels. It uses a rail system with ZX522 busbar holders and a WR mounting frame, enabling horizontal alignment, straightforward mounting, and clean, scalable layouts. It is suitable for new builds and incremental upgrades in industrial control cabinets.
The unit is rated for up to 400 V maximum operating voltage and 850 A nominal current, supporting a 3-pole arrangement. It is designed to house up to 60 DIN place devices and excludes internal NH disconnector devices, making it ideal for main distribution or panel feeders in automation environments while maintaining safe, compliant operation.
Yes, it suits high-density, modular distribution needs common in data centers and manufacturing lines. Its 60 DIN places, 850 A capacity, horizontal busbar alignment, and CombiLine compatibility support scalable control architectures, fast commissioning, and straightforward future expansions, all within a compact 250 mm width and 275 mm built-in depth footprint.
The module carries CE declarations and complies with DIN EN 61439-3 (and DIN EN 61439-2), ensuring safe distribution panel performance. It is RoHS and REACH compliant, with WEEE and SCIP considerations for end-of-life and sourcing transparency, supporting regulatory governance in most regional markets.
By enabling modular, plug-and-play device additions within a fixed busbar framework, the module reduces install time and rework, lowering labor costs. Its standardized enclosure and mounting frame simplify future upgrades and maintenance, improve fault isolation, and promote consistent protection across devices, yielding faster time-to-production and lower lifecycle costs.
