Feature → Business Impact → Application: 3P main circuit breaker interior fitting module supports Tmax XT4 and up to 250 A, enabling dense, safe protection within compact panels. This translates to reduced cabinet footprint and faster wiring, improving overall system density for critical power distribution in manufacturing lines. Application: modular distribution panels in steel or composite enclosures where space is at a premium and up-to-date protection is mandatory. Feature → Business Impact → Application: 36 DIN place units and a 250 mm width allow scalable layouts without overhauling panel architecture, reducing rework and design time for multi-circuit installations. Application: upgrade paths for existing CombiLine installations that require planned capacity increases while preserving standard mounting schemes. Feature → Business Impact → Application: 400 V operating voltage and 3P configuration deliver reliable protection for three-phase loads, supporting consistent trip performance and energy management in industrial drives. Application: motor control centers and distribution panels with high current demands. Feature → Business Impact → Application: Enclosure mounting frame options WR or EDF enable flexible integration with a variety of cabinet families, enhancing compatibility and decreasing custom fabrication time. Application: retrofit projects or new builds across facilities with diverse enclosure inventories. Feature → Business Impact → Application: Light grey RAL 7035 housing and plastic Covers offer durable, aesthetically consistent panel interiors, simplifying field service and maintenance. Application: elevated factory aesthetics alongside practical durability. Feature → Business Impact → Application: RoHS and REACH declarations, plus CE conformity, ensure regulatory compliance and safer material handling in supply chains and end-user maintenance. Application: markets with strict environmental and product-safety requirements. Feature → Business Impact → Application: Documentation and mounting instructions (MBA191T series) provide clear implementation paths, reducing installation errors and warranty risks. Application: rapid onboarding for technicians and streamlined project handoffs for system integrators.

FAQs
Installation follows the MBA191T mounting instructions, with ready-to-mount interior fittings for 36 DIN units. Use the WR or EDF enclosure mounting frame to align with your cabinet layout, and connect the XT4 MCCB per the standard three-pole configuration to ensure proper clearance and safe operation.
Yes. The interior fitting module is designed to accommodate one XT4 MCCB within a 3-pole, 250 A system, using a 36 DIN unit layout and the CombiLine grid, enabling a compact yet robust protection solution inside standard panels.
The module carries CE conformity and complies with DIN EN 61439-3/2 for distribution panels. It also meets RoHS and REACH requirements, with WEEE declarations indicating end-of-life considerations and material safety for regulated markets.
Key dimensions are 250 mm width, 450 mm height, and 200 mm depth, with 36 DIN places. This enables 1 mountable device in an interior fitting module designed for 3-pole Tmax protection within modular panels.
The component reduces panel footprint and assembly time, supports scalable protection for industrial loads, ensures regulatory compliance, and simplifies maintenance through standardized mounting and documented installation procedures, delivering faster time-to-value and lower lifecycle costs.
