There is no defined size for busbar supports. Busbar supports are available in a broad range of sizes and shapes to suit different applications. Within Termate’s MX range, for example, there are thee lengths: 210 mm long. 273 mm long and 350 mm long.

The size of the support is often decided by the phase centre of the support. If you look at Termate’s busbar support ranges like the VMS (Versatile Mounting Support) each phase is a single VMS block rather than a multiple phase block and can be used at whatever phase centre a customer needs, but we also offer spacers that allow them to have a set phase centre to achieve higher fault ratings.

The size of the busbar support is also determined by the thickness of the conductor being held, the number of conductors per pole, and the orientation of the conductor (either flat or on edge). If you need assistance determining which busbar support would best meet your needs, speak to our technical sales team.
