Product details
Designed for railway signaling systems, WAGO Corporation's 254-844 delivers unmatched reliability in Terminal Blocks - Wire to Board applications. This EN 50155-compliant terminal block withstands severe vibration and temperature extremes encountered in rolling stock. The 510KBA-BAAG variant features fail-safe interlocking for mission-critical train control applications.The 1 crash-resistant design meets UIC 651 standards. The interlocking mechanism maintains connectivity during 50G impact scenarios.With 1 power-rated contacts, the block handles traction system currents. Each position features arc runners that safely extinguish 1500A breaking currents.45° (135°) Angle with Board configuration accommodates gangway cable routing. The underfloor-mounted version resists ballast impact and track debris.Rated for 10 A with 100% duty cycle, the contacts use sintered tungsten composites. The material withstands pantograph arcing without contact welding.The 300 V rating exceeds 25kV AC catenary requirements. Creepage extenders prevent tracking across polluted insulator surfaces.Compatible with 12-20 AWG railway-grade cables, the termination resists flex fatigue. The spring-loaded design compensates for 10 million vibration cycles.Through Hole attachment survives 5Hz-150Hz random vibration. The floating mount design isolates PCB from carbody resonance frequencies.The Screwless - Leg Spring, Push-In Spring method complies with EN 50343 wiring standards. The cold-applied compression system eliminates thermal stress on adjacent components.The Blue coding follows UIC 560 visibility standards. Retroreflective markings remain visible in tunnel lighting conditions.
