Feature → Business Impact → Application: The unit provides 36 DIN place units in a 250 mm wide interior fitting module, enabling standardized layout and predictable wiring routes. This reduces installation time and minimizes misalignment during cabinet assembly, improving overall project timelines for distribution panels. Application: Ideal for 4P MCCB XT5 integrations in CombiLine configurations. Feature → Business Impact → Application: 4-pole XT5 device compatibility supports full Tmax protection with a 400 A rating, delivering reliable short-circuit protection while simplifying spare parts planning and serviceability. Application: Suitable for industrial cabinets requiring robust 4P protection. Feature → Business Impact → Application: Enclosure Mounting Frame options WR or EDF provide flexible integration into a range of cabinet footprints, enabling retrofits and new builds without extensive structural changes. Application: Retrofit projects or new-control cabinets in automation plants. Feature → Business Impact → Application: 90-degree press and turn closure ensures secure, vibration-resistant operation and faster assembly, reducing field adjustments and maintenance calls. Application: Mechanical reliability in harsh industrial environments. Feature → Business Impact → Application: Regulatory compliance features including RoHS, REACH, and CE declarations minimize compliance risk and support global deployments. Application: Global panel builders delivering compliant protection systems. Feature → Business Impact → Application: Documentation notes that devices are excluded (Enclosure Equipment Excludes Devices), clarifying procurement paths and reducing ambiguity in bill of materials. Application: Clear integration with external MCCB XT5 procurement for scalable protection schemes.

FAQs
Yes. This interior fitting module is designed to house an XT5 MCCB within a 4P Tmax configuration. It uses 36 DIN positions and fits 250 mm wide, 450 mm high cabinets with a 225 mm built-in depth, following WR or EDF mounting frames. For best results, follow the MBA192XT/MBA292XT/MBA198XT installation guides and ensure the MCCB is sized to 400 A within the DIN rail layout.
The module supports compliance with DIN EN 61439-2 and DIN EN 61439-3, along with CE marking, RoHS compliance, and REACH declarations. These standards ensure safe electrical protection, reliable panel assemblies, and regulatory alignment for global installations.
Yes. The module is designed for a rated current of 400 A and a 4P configuration, enabling Tmax protection in 400 V systems. It integrates within a 250 mm width, 450 mm height cabinet with a 225 mm built-in depth, making it suitable for compact, high-current distribution panels.
The interior fitting module is provided as a frame-ready enclosure component; devices (MCCBs) are excluded. Plan to procure XT5 MCCBs separately. The module supports 36 DIN unit configurations and is compatible with WR or EDF mounting frames for flexible integration.
The predefined DIN rail footprint, standardized 36 DIN positions, and RoHS/REACH/DIN EN 61439-2/3 compliance reduce commissioning time and maintenance complexity. In production environments, this translates to faster troubleshooting, consistent electrical protection, and lower risk of non-compliance during audits.
