Further Details:
The automatic circuit breakers of the S200MT series are particularly suitable for railway applications and protect cables and lines in accordance with DIN VDE 0100-430 and DIN VDE 0100-530 against overload and short circuit. They comply with the standards DIN VDE 0641-11 and IEC/EN 60898-1, DIN VDE 0660-101 and IEC/EN 60947-2, hazard level R26/HL3 according to DIN EN 45545, as well as requirement level 3 according to NF F 16-101/102 (I2-F3) and category 1 - class A/B (mounted) according to IEC 61373. Their patented terminal connection system ensures easy and secure contact and handling through a pressure plate. For better visibility during wiring, the connection opening for cables 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 directly connected via the terminal with insulation in protection class IP20. The extensive range of accessories provides everything needed for installation tasks. Each device undergoes three intensive tests for quality and performance before delivery.
