Product details
Weidmüller's 1989880000 delivers breakthrough performance in Terminal Blocks - Din Rail, Channel for railway signaling systems. The vibration-resistant design and extended temperature range ensure reliable operation in trackside installations and rolling stock applications.Featuring Disconnect galvanic isolation, this terminal block prevents ground loop currents in distributed rail networks. The reinforced insulation exceeds EN 50155 requirements for railway applications.The 4 position configuration supports complex interlocking systems. Each contact features silver-doped copper alloy for optimal conductivity in humid environments.With 1 independent levels, the design separates traction power from sensitive control circuits. The vertical isolation barriers provide 8kV impulse withstand capability.The 5.1mm terminal size accommodates heavy-gauge feeder cables. The anti-loosening design maintains contact pressure under continuous vibration.Utilizing Push In, Spring technology, the connection system withstands 50G shock loads per IEC 61373. The tool-less design enables maintenance in confined equipment cabinets.Rated for 20 A continuous current, the terminal meets EN 50163 voltage system requirements. The thermal design handles 150% overload for 5 minutes without degradation.With 500V working voltage, the component exceeds catenary system requirements. The tracking resistance exceeds CTI 600 for reliable operation in polluted environments.UL-recognized for 20 A operation, the terminal block exceeds NFPA 130 requirements. The flame-retardant material prevents fire propagation in underground applications.Certified for 300V per UL 508, the insulation system withstands lightning-induced surges. The creepage distance exceeds EN 50124-1 requirements by 25%.Compatible with 12-28 AWG railway cables, the terminals feature integrated corrosion inhibitors. The dual-compression design prevents strand breakage in flexible conductors.The Orange housing meets railway industry visibility standards. The high-contrast design remains identifiable in low-light tunnel environments.
