Product details
Designed for railway signaling systems, TE Connectivity AMP Connectors's 1776121-3 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 3 power-rated contacts, the block handles traction system currents. Each position features arc runners that safely extinguish 1500A breaking currents.0.200" (5.08mm) spacing prevents flashover in 3000m altitude operations. The hydrophobic coating sheds conductive ice accumulation.Vertical with Board configuration accommodates gangway cable routing. The underfloor-mounted version resists ballast impact and track debris.Rated for 13.5 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 15-17 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 Screw - Rising Cage Clamp method complies with EN 50343 wiring standards. The cold-applied compression system eliminates thermal stress on adjacent components.The Black coding follows UIC 560 visibility standards. Retroreflective markings remain visible in tunnel lighting conditions.
