Sizes
• The devices are matched to the dimensions, connections and
technical features of the other devices in the SIRIUS modular
system.
• The devices permit mounting of slim-line and compact load
feeders in widths of 45 mm (S00 and S0) or 55 mm (S2).
• The devices make con󹪝guration easier.
S00, S0, S2 S00, S0, S2
Current range
• The devices are matched to the other devices in the SIRIUS
modular system
• Just 1 option per size with a wide setting range makes con‐
󹪝guration easy.
