Product details
The 1939470000 by Weidmüller pioneers new Terminal Blocks - Power Distribution technology for railway traction systems. Engineered for high-vibration environments, it delivers robust power distribution while withstanding the mechanical stresses of continuous rail operation.As a railway-approved Power Distribution Block, this solution exceeds international standards for shock resistance and long-term reliability in mass transit applications.The 1-pole configuration provides isolated power channels for traction motors, auxiliary systems, and onboard electronics in modern rail vehicles.With 1 line side inputs, the terminal block accommodates both overhead catenary and third-rail power collection systems.Featuring 11 load side outputs, this design enables efficient power distribution to multiple traction converters while preventing electromagnetic interference.The Screw Connection interface employs spring-loaded contacts that maintain connectivity despite constant vibration and mechanical shock.Utilizing Screw Connection technology, the solution provides tool-less maintenance access for rapid servicing during scheduled depot maintenance.Rated for 690 V operation, this component meets railway standards for isolation and surge protection in electrified track environments.With 250 A current capacity, the design handles the dynamic power requirements of high-speed trains during acceleration and regenerative braking.
