Feature → Business Impact → Application: The 4P 160 A MCCB built into the Tmax interior fitting module delivers robust fault protection without compromising panel space, enabling compact but capable control cabinets. This translates to higher system availability in manufacturing lines and data centers where space is at a premium. Application-wise, it suits 400 V distribution panels in industrial automation, where DIN 436 place units and CombiLine configurations are the norm. Feature → Business Impact → Application: The enclosure is designed for an ETIM-compliant, WR or EDF mounting frame, and the unit is ready for XT2 integration. This reduces installation time and ensures reliable busbar connections, especially in modular panel lines and retrofit projects. Feature → Business Impact → Application: RoHS and REACH declarations paired with CE conformity give you streamlined compliance, lowering risk during audits and accelerating procurement cycles for regulated industries. Feature → Business Impact → Application: The module’s interior fitting design and 90-degree closure improve thermal performance and ease of service, supporting predictable maintenance schedules and lower lifecycle costs in continuous-process environments. Feature → Business Impact → Application: With 36 DIN place units and a 250 mm width by 450 mm height footprint, engineers can plan future expansion without reconfiguring the entire panel, enabling scalable protection for growing systems.

FAQs
The 2CPX043420R9999 is designed as an interior fitting module for CombiLine enclosures, featuring a 36 DIN unit footprint (DIN place units) and a 4P MCCB platform. It supports the XT2 device option and comes in a WR/EDF mounting frame configuration, enabling straightforward integration into standard cabinet builds. It does not include devices, so XT2 or other protection modules must be mounted separately.
Key specifications include a maximum operational voltage of 400 V, nominal current I n of 160 A, and rated operational current I e of 250 A. The device is a 4-pole configuration with 1 RCD, designed for 400 V distribution panels and CombiLine interiors. It is intended for applications requiring reliable overload and short-circuit protection within Tmax families and 4P protections.
Yes, it is suitable for 400 V industrial distribution panels. It occupies a 36 DIN unit footprint with 250 mm width and 450 mm height, and a built-in depth of 200 mm, making it compatible with standard 200 mm cabinet depths. This supports compact panel design while preserving service accessibility and safe clearance for busbars and wiring.
The module adheres to DIN EN 61439-2 and DIN EN 61439-3 standards, and carries CE conformity. RoHS compliance is confirmed under EU Directive 2011/65/EU with Amendment 2015/863, and REACH declarations are provided. WEEE considerations place the product within typical European electronics handling guidance. These certifications streamline regulatory audits and supplier qualification processes.
The XT2-compatible interior fitting design enables quick device replacement or upgrade, reducing downtime during maintenance. The robust Tmax protection and 400 V rating support long service life in demanding environments, while RoHS/REACH compliance mitigates material substitution risk. Together with space-efficient DIN rail compatibility and industry-standard dimensions, the module helps lower lifecycle costs and improve ROI through predictable maintenance and faster commissioning.
