The 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/EN60947-2. Their patented connection terminal ensures simple and safe contact and handling using a pressure plate. Conductor cross-sections of up to 35 mm² can be connected directly to the device via the connection terminal with insulation in protection class IP20. Contact is made directly via the plug-in base system and the outer conductor contact can be freely selected (L1, L2 or L3). The extensive range of accessories offers you everything you need for your installation tasks. Numerous approvals make the S 400 fit for worldwide use. Each device is subjected to three intensive tests for quality and performance before delivery.
