FAQs
Yes. The SV 9666.583 is designed for 40 x 10 mm busbars with a 100 mm centre-to-centre spacing and fits a 750 mm by 450 mm footprint. It supports 10 x size 00 configurations and aligns with SV 9346xxx frames, simplifying panel design and ensuring consistent electrical clearances. Ensure the supplied assembly parts are used during installation to maintain performance and safety margins.
To ensure safe cable connections, install the contact hazard protection module or an N/PE busbar module above or below the NH slimline fuse-switch disconnector modules as noted in the documentation. This setup reduces exposure to live conductors and helps maintain proper creepage and clearance distances within the enclosure. Follow the included assembly parts and the SV frame guidelines for a compliant, reliable installation.
This module is ideal for power distribution in control cabinets, switchgear assemblies, and other enclosures requiring NH slimline fuse-switch disconnectors. It supports 3 WU (750 mm) and 3 U (450 mm) configurations and fits 10 × size 00 busbar layouts, enabling scalable, modular protection and isolation within standard enclosures used in manufacturing and process automation.
Verify CE marking, IP ratings, and SIL/PL requirements with the supplier or your compliance team, since the data set does not specify these certifications. Cross-check with Rittal documentation and local regulations to ensure the module meets your environment, hazard, and performance criteria before deployment in critical applications.
The product is supplied as a single pack per order, with a weight of approximately 3.34 kg per pack. This predictable weight helps with shipping, palletizing, and on-site handling. When planning installation, account for the enclosure width of 750 mm and height of 450 mm to maintain clearances and safe access during maintenance.
