ABB 1STQ007406A0000 Main Distribution Board - TBBS

Mounting flexibility is a core feature, with Kit or Pre-assembled configurations that fit your installation approach. This reduces commissioning time and minimizes on-site wiring errors, boosting first-pass electrical integrity. It is particularly suited for System pro E Power modular boards, enabling scalable distributions in industrial facilities. Flat copper busbars 63x5 mm, length 1750 mm provide a low-impedance path for high current and precise current sharing. The busbar design reduces contact resistance and improves thermal performance, supporting safer operation in continuous duty environments. This combination is ideal for Main Distribution Boards in manufacturing lines, process plants, and large machine rooms. Compliance and environmental features ensure regulatory alignment and responsible product stewardship. CE Declaration 1STC860111, RoHS information aligned with EU Directive 2011/65/EU, REACH declaration 1SDL000282R1279, and WEEE categorization support regulatory compliance and safe end-of-life handling. Documentation and installation support streamline field work. Included manuals cover System pro E power TBBS installation and busbar holder scaling, with references to 1STC803005D0208 data sheet and 1SDC007110G0902. This reduces risk, accelerates training, and lowers total cost of ownership over the system lifecycle. Dimension and compatibility options offer planning flexibility. Reference depths of 300–1000 mm, heights from 1400 to 2200 mm, and widths from 400 to 1600 mm let you tailor the enclosure to an existing cabinet or room constraints. With a weight of approximately 4.46 kg per package, this product is straightforward to handle during on-site installation.
