SASY 60i Busbar System

SASY 60i Busbar SystemTechnical Data on the 60 mm SystemBusbars according to EN 13601The UL 508A standard limits the permissible current density for busbars to a value of 1000 A / inch2 (1.55 A /mm 2 ).The higher current carrying capacities to DIN 43671 were obtained under operating conditions.The busbar temperature is normally positively influenced by mounting components on the busbar and by air circulation within the installation.Depending on the respective ambient temperature, you can calculate the correction factor k2 according to DIN 43 671 for flat busbars.If ambient conditions change, a correction factor needs to be taken into account.On the other hand, increased loads may occur if the components feature a correspondingly high temperature resistance.A 30 x 10 tin-plated busbar can under normal conditions be loaded with 630 A . With a load of 800 A, for instance, a k2 correction factorof 1.3 is necessary. If follows from the diagram that with this factor and 35 °C air temperature, the busbar heats up to approx. 85 °C.Base plateSilicon-free, chlorine-freeTemperature resistant up to 110 °CSelf-extinguishing according to UL 94Busbar coversfor busbars of 12 x 5, 12–30 x 5, 12–30 x 10Double-T-ProfilesSilicon-free, chlorine-freeTemperature resistant up to 110 °CSelf-extinguishing according to UL 94Modular system coverto be attached to 60 mm systems, 3-poleto busbars of 12/20/30 x 5/10, 25 x 5to double-T-profilesCover profileCover profileCover profilefronttop/bottomsupportSilicon-free, chlorine-freeTemperature resistant up to 120 °CSelf-extinguishing according to UL 94For types and art. numbers see page 7, 925
