Introducing the new 400R wire and cable.

TE Connectivity is launching the 400R as a new rail-approved wire and cable product for the US market.

The 400R is US rail approved, limited fire hazard, wire and cable compliant to the NFPA 130-2010 standard, meaning that the wire will be approved on most US rail projects.


With TE Connectivity’s polymer and cross-linking technology, the dual-wall jacket insulation is:

  • Lightweight and thin-walled for reduced bundle volume and total weight
  • Approximately 30% lighter than conventional thick-walled wire, giving significant energy savings to the end user
  • Approximately 50% saving in bulk of wire giving more room for the train designer, builder and passengers
  • Compliant to US rail standards NFPA 130 and BSS standards, meaning it is suitable to be used in passage trains close to passengers

Main characteristics:

  • Temperature rating 150°C continuous
  • Voltage rating 600V, 1,000V, 2,500V
  • Robust dual-wall design resists damage and stops notch propagation
  • Small size that allows for easy installation
  • Good electrical performance from core layer
  • Smaller and lighter than bulky CPE
  • Good oil resistance
  • Reduced operating costs
  • Low smoke and fume emissions under fire conditions
  • Highly flame retardant
  • Meets NFPA 130


  • Rail market rolling stock
  • Underground metro tunnels
  • All signal and power applications for wire and cable in rolling stock and tunnels


  • NFPA 130 – 210
  • BSS7238
  • BSS7239
