The circuit breakers of the S200MT series are specifically designed for the railway sector and protect cables and lines against overload and short circuit according to 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, hazard level R26/HL3 according to DIN EN 45545, and requirement class 3 according to NF F 16-101/102 (I2-F3) as well as category 1 - class A/B (mounted) according to IEC 61373. Their patented connection terminal ensures easy and safe contact and handling via a pressure plate. For better visibility when wiring, the connection opening for conductors is positioned above the connection opening for the phase rail. The actual switching position is displayed through a viewing window, even when the switching lever is blocked. Conductor cross-sections up to 25 mm² can be directly connected to the device via the terminal with insulation in protection class IP20. The extensive range of accessories provides everything you need for your installation tasks. Each device undergoes three intensive tests for quality and performance before delivery.
