Product details
Weidmüller's 7940029428 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 Fuse, Lever mechanism enables safe isolation during track maintenance. The bright orange actuator provides clear visual indication of circuit status.The 3 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 17.8mm terminal size accommodates heavy-gauge feeder cables. The anti-loosening design maintains contact pressure under continuous vibration.Utilizing Screw technology, the connection system withstands 50G shock loads per IEC 61373. The tool-less design enables maintenance in confined equipment cabinets.Rated for 32 A continuous current, the terminal meets EN 50163 voltage system requirements. The thermal design handles 150% overload for 5 minutes without degradation.With 690V working voltage, the component exceeds catenary system requirements. The tracking resistance exceeds CTI 600 for reliable operation in polluted environments.UL-recognized for 30 A operation, the terminal block exceeds NFPA 130 requirements. The flame-retardant material prevents fire propagation in underground applications.Certified for 600V per UL 508, the insulation system withstands lightning-induced surges. The creepage distance exceeds EN 50124-1 requirements by 25%.Compatible with 4-18 AWG railway cables, the terminals feature integrated corrosion inhibitors. The dual-compression design prevents strand breakage in flexible conductors.Integrated LED support condition-based maintenance strategies. These smart diagnostics interface with railway asset management systems via IEC 61375.The Beige housing meets railway industry visibility standards. The high-contrast design remains identifiable in low-light tunnel environments.Designed for 10.3mm x 38mm railway protection devices, the fuse carrier meets EN 50123 standards. The quick-change design minimizes downtime during preventative maintenance.
