Feature → Business Impact → Application: The Tmax interior fitting module accommodates a 4P main circuit breaker rated up to 250 A within 48 DIN space units, enabling 400 V operation in compact panels. This maximizes space efficiency while delivering reliable overload protection, reducing panel footprint and wiring complexity for panel builders. Use in CombiLine panel systems where Tmax protection is required in cabinets with 500 mm width and 300 mm height. Paragraph 2: Feature → Business Impact → Application: The enclosure supports 2 mountable devices and offers a 90-degree press-and-turn closure with a closed cover, improving installation speed and operator safety. This design reduces field servicing time and protects connections from dust, ideal for panel builders integrating Tmax modules into standard 215 mm built-in depth cabinets. Paragraph 3: Feature → Business Impact → Application: Enclosure mounting frames WR or EDF provide flexible installation options across a range of cabinet depths. This flexibility minimizes retrofits and enables seamless integration with existing CombiLine panel systems, saving commissioning time for project teams. Paragraph 4: Feature → Business Impact → Application: RoHS and REACH declarations with CE conformity and a WEEE-compliant approach ensure regulatory compliance across EU markets, reducing risk during procurement and audits. For system integrators in industrial automation, this translates to smoother approvals and fewer last-minute changes in order documentation. Paragraph 5: Feature → Business Impact → Application: With a 500x300x215 mm footprint and 48 DIN places, plus a built-in depth of 215 mm, the module fits standard switchboards and simplifies panel planning. The precise dimensions and modest weight (1.73 kg) support predictable mounting and easier handling during installation in 300 mm-high cabinets. Paragraph 6: Feature → Business Impact → Application: Rated for 400 V operation with 4 poles and a Tmax busbar system, it supports 250 A continuity and XT2 compatibility for modular MCCBs. This compatibility reduces component variety on the shop floor and accelerates procurement for electrical distributors and panel builders.

FAQs
The interior fitting module is designed to mount up to two XT2 MCCBs within a 4P Tmax arrangement. It excludes devices, so you can select XT2 variants that fit the 250 A rating. The enclosure supports a 500x300 mm footprint and 48 DIN spaces, ensuring straightforward integration into CombiLine cabinets and preserving modularity for future upgrades.
Key specifications include rated current up to 250 A, maximum operating voltage up to 400 V, and 4 poles (4P). It is designed for 400 V operation with a 48 DIN space layout, 500x300x215 mm dimensions, and a weight of about 1.73 kg. It supports Tmax protection within standard interior fittings and aligns with DIN EN 61439-3/2.
Yes. The module carries CE marking with EU Declaration of Conformity, is RoHS compliant under EU Directive 2011/65/EU and Amendment 2015/863, and includes REACH declarations. It also notes WEEE category considerations, helping ensure regulatory alignment across EU markets and smoother supplier onboarding.
Installation benefits include a 90-degree press-and-turn closure for quick access, a modular interior fitting design that simplifies wiring, and WR or EDF mounting frame compatibility for flexible cabinet integration. The 48 DIN spaces and 500x300 mm footprint support predictable planning, faster commissioning, and easier retrofits in existing CombiLine systems.
It reduces installation time, lowers risk through established DIN EN 61439-3/2 compliance, and minimizes procurement complexity by offering XT2 compatibility and documented RoHS/REACH declarations. For project timelines, distributors, and maintenance teams, this translates to fewer change orders, better audit readiness, and predictable lifecycle costs in industrial automation projects.
