The circuit breakers of the S200MT series are specifically designed for the railway segment and protect cables and lines against overload and short circuits in accordance with DIN VDE 0100-430 and DIN VDE 0100-530. They meet the construction regulations DIN VDE 0641-11 or IEC/EN 60898-1, DIN VDE 0660-101 or IEC/EN 60947-2, 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 terminal block ensures easy and secure contact and handling via a pressure plate. For better visibility during wiring, the connection opening for conductors is located above the connection opening for the phase rail. The actual switching position is displayed through a viewing window, even when the switch lever is blocked. Conductor cross-sections of up to 25 mm² can be connected directly to the device via the terminal block 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.
