FAQs
The SV Busbar module is designed for bus-mounting fuse bases E18, E27, E33 and D-Switch along with NH fuse-switch disconnectors. Start by aligning the 12 x 5/10 mm busbars to the 60 mm center distance, then secure the module in a 250 mm by 300 mm face area (1 WU by 2 U). Use the supplied assembly parts to fasten the bases, ensuring proper insulation and clearances. This approach reduces mounting time and minimizes misalignment, improving overall switchgear reliability.
Article number SV 9666.520 corresponds to the SV Busbar module (ISV), 1 WU (250 mm) and 2 U (300 mm). It uses a polystyrene cover and fibreglass-reinforced plastic holder, is color-matched to RAL 7035, and ships with assembly parts. The pack weight is 0.74 kg, and it is designed to fit 12 x 5/10 mm busbars, with compatibility to model 3418.010. These specs support consistent, repeatable mounting across multiple enclosures.
The SV 9666.520 module is intended for assembling busbar bases E18, E27, E33 and D-Switch as well as NH fuse-switch disconnectors (3-pole, 60 mm bar center distance). This makes it suitable for standard control panels requiring compact, reliable protection and switching arrangements, while maintaining alignment with common fuse and disconnect components.
The SV Busbar module aligns with ETIM 9 (EC002525) and ECLASS 8.0 (27400610) classifications, helping procurement platforms categorize and compare parts consistently. It also carries the EAN 4028177676404, aiding barcode-based stock management and automated purchasing workflows.
Using the SV Busbar module improves installation speed, ensures precise mounting tolerances, and reduces time-to-commission for switchgear. Its standardized dimensions and compatibility with multiple fuse bases and disconnectors help lower spare-parts inventory, boost safety with robust materials, and support scalable enclosure design across production lines.
