Benefits of busbar systems over wiring

Compared to conventional enclosure wiring, Rittal's 60 mm busbar systems offer users significant technical benefits. It goes without saying that these benefits also have a positive effect during planning and assembly and on the costs associated with them.

You can clearly see the differences in terms of available space and tidiness by having a look at the design sample from the US market (see picture). The conventional wiring shown in the right-hand picture requires significantly more mounting surface area than the 60 mm busbar configuration shown in the left-hand picture and is less organised.

What the picture fails to show, however, is the full extent of all the system's benefits. Please find below the essential arguments for using 60 mm busbar systems:

1. Less space required since the number of cables used for wiring is reduced

2. Enhanced short-circuit resistance3. Less calculation work required to certify short-circuit resistance4. Less contact points (less errors)5. Less work required for assembling cables such as pressing ring

terminals6. Reduced heat loss7. The assembly is better organised which means power parts can

clearly be distinguished from control parts so that troubleshooting is simplified

8. Large cable outlets can be connected more easily9. A broad range of accessories for almost every application10. Reduced assembly time for punching/deburring/thread tapping11. Less work required for retrofitting units12. Type tested system components
