What Are Phoenix Contact Spring Terminal Blocks?

Phoenix Contact Spring Terminal Blocks are high-performance wiring components designed for fast, vibration-proof, maintenance-free connections. Using a spring-cage mechanism instead of traditional screws, these blocks ensure consistent clamping force and improved reliability in demanding environments. They are widely preferred for automation, transportation, electronics, machine wiring, and high-vibration applications.

  • The established connection technology for applications that are sensitive to vibration.
  • It provides a large insertion space, allowing conductors with a nominal cross-section to be connected both with and without ferrules.
  • The double bridging shaft enables flexible bridging; both alternate and continuous bridging options are available.
  • ATEX approval is standard for all feed-through terminal blocks, with a connection capacity ranging from 0.04 to 35 sq.mm.
