Interior fitting module for CombiLine enables compact cabinet design while maintaining robust busbar compatibility, reducing overall footprint and enabling faster assembly in distribution cabinets. Feature → Business Impact → Application: The 4P configuration with a maximum 400 A rating provides clear protection for critical loads; this translates to safer operation and lower fault risk in medium-voltage panels, especially where space is premium and reliability is paramount in data centers and industrial sites. Enabled by a 750 mm wide and 450 mm high footprint, the module fits standard cabinet deductions and supports seamless integration with the 4-pole busbar system, making retrofits quicker and less invasive for existing installations. Other benefits include a plastic enclosure cover in light grey (RAL 7035) with 90-degree press-and-turn closure, improving user access and reducing maintenance time in field service. The enclosure is designed as an interior fitting module (Excludes devices), with WR mounting frame for straightforward installation in ready-made ABB panels.

FAQs
The module is designed for cabinet depths up to 275 mm with a width of 750 mm and a height of 450 mm, integrating into CombiLine interior fittings. It accommodates 108 DIN place units and supports a 4P, 400 A configuration, enabling a compact yet scalable distribution solution in 3 U cabinet layouts.
It is specifically engineered for 4-pole operation with a 4-pole busbar system, enabling reliable protection across all poles. The interior fitting module accepts one OX315-400 device and uses a WR mounting frame, ensuring straightforward wiring, accessibility, and consistent electrical performance in panel assemblies.
Yes. The module aligns with DIN EN 61439-3 and DIN EN 61439-2 standards, and carries RoHS declarations and REACH information. This supports compliant, safe installation in European panel systems and reduces risk during regulatory audits.
Maintenance focuses on verifying enclosure integrity, ensuring 90-degree closure operation, and confirming device mounting remains secure. The design excludes devices internally, simplifying inspection and replacement of subsystems. Refer to MBA250ALT / MBA400ALT / MBA401ALT mounting instructions for proper re-assembly after service.
Benefits include reduced installation time due to a standardized interior fitting module, lower lifecycle costs from durable, maintenance-friendly enclosure design, and improved safety through regulated 4P protection. The compact 750x450x275 mm footprint allows higher cabinet density, enabling faster project delivery and predictable procurement within CombiLine systems.
