The FBS range provides a compact, adaptable solution for supporting flat copper conductors in low-voltage distribution assemblies.
Built from high-strength glass-reinforced polyamide 6.6, each busbar support achieves Icw fault ratings up to 50 kA for 1 s.
Its modular, stackable design lets engineers combine top and bottom sections to achieve the required conductor spacing and configuration.
This flexibility makes FBS busbar supports ideal where multiple conductor sizes or layouts are used, helping reduce component counts while maintaining safe electrical separation and reliable mechanical performance.
