The 24-DIN interior fitting module delivers high-density space utilization, enabling 24 DIN spaces in a single enclosure, which reduces panel footprint and wiring complexity, speeding up installation in modern automated systems. This feature translates to measurable business impact: faster project delivery, lower installation costs, and easier future upgrades in CombiLine modular distribution panels for Tmax systems. The 4P main circuit concept supports a maximum 160 A rating, providing reliable protection for high-current applications in process and factory automation, with a busbar system designed for 4-pole layouts. Compatibility with WR or EDF mounting frames adds flexibility for different cabinet architectures, while the 90-degree press-and-turn closure simplifies field assembly and service access. In practice, panel builders gain repeatable, compliant installations with reduced risk of miswiring and fewer field modifications.

FAQs
The module fits 24 DIN spaces within an interior fitting module, designed for CombiLine modular distribution panels. It supports WR or EDF enclosure mounting frames and uses a 90-degree closure for easy installation. Note that it is unequipped for pre-installation of one MCCB XT2, though XT2 can be added in field configurations. It is intended for 4-pole Tmax protection with a maximum 160 A rating and a 4-pole busbar system.
Key electrical specs include a rated operational voltage up to 400 V and a nominal voltage of 400 V, with a rated current of 160 A. It features 4 poles, options for one mountable device, and is designed as a Tmax main circuit breaker enclosure component. Dimensions and weight support compact panel layouts suitable for factory automation and process control environments.
Yes. The interior fitting module is expressly designed for CombiLine modular distribution panels and Tmax applications. Its 24 DIN places and compatible enclosure frame options enable scalable protection within standardized panel builds, reducing custom fabrication time and enabling consistent installation practices across multiple projects.
The unit aligns with DIN EN 61439-2 and DIN EN 61439-3 standards and carries CE conformity. RoHS compliance confirms restricted substances in line with EU Directive 2011/65/EU and amendment 2015/863, with REACH declarations ensuring regulatory clarity. It also notes WEEE categorization, clarifying end-of-life handling for safe disposal.
The module offers space-efficient, compliant integration into Tmax-based panels, reducing cabinet footprint and wiring complexity. With 24 DIN spaces and standardized mounting, project timelines shorten, commissioning becomes more predictable, and future upgrades (such as XT2 MCCBs) can be added with minimal rework. The result is lower total cost of ownership and improved reliability in industrial automation applications.
