The automatic circuit breakers of the S 400 series protect cables and lines against overload and short-circuit in accordance with DIN VDE 0100-430 and DIN VDE 0100-530. They comply with the construction regulations DIN VDE 0641-11 or IEC/EN 60898-1, DIN VDE 0660-101 or IEC/EN 60947-2. Their patented connection terminal ensures simple and safe contacting and handling by means of a pressure plate. Conductor cross-sections of up to 35 mm² can be connected directly to the unit via the terminal with insulation in protection class IP20. Contacting is made directly via the plug-in socket system, and the outer conductor contacting can be freely selected (L1, L2, or L3). The extensive range of accessories offers everything needed for installation tasks. Numerous approvals make the S 400 fit for worldwide use. Each unit is subjected to three intensive tests for quality and performance before delivery.
