PT 4-WE/38 - Panel feed-through terminal block

Panel feed-through terminal block, nom. voltage: 500 V, nominal current: 24 A, number of connections: 76, number of positions: 38, connection method: Push-in connection, Rated cross section: 4 mm2, cross section: 0.14 mm2 - 4 mm2, mounting type: Wall mounting, color: gray

  • Easy grouping with engagement pin versions
  • Easy connection of the conductors, thanks to fast Push-in spring connection
  • CLIPLINE complete accessories for easy bridging, testing, and marking
  • Highly flexible, thanks to alignable single terminal blocks
  • Automatic compensation of the panel thickness via the snap principle integrated in the insulation housing

PT

The Phoenix Contact PT Series comprises feed-through terminal blocks that utilize Push-in connection technology, offering efficient and reliable wiring solutions for various industrial applications. These terminal blocks are designed for straightforward conductor insertion, enhancing installation speed and ensuring secure connections.

Key Features:

  • ✅ Push-in Connection Technology: The PT Series employs a direct plug-in method, allowing solid conductors or conductors with ferrules to be inserted easily without the need for tools. This design facilitates quick and reliable wiring.
  • ✅ Compact Design: The terminal blocks feature a space-saving form factor, making them suitable for applications where installation space is limited.
  • ✅ High Electrical Ratings: Depending on the specific model, the PT Series terminal blocks can handle nominal voltages up to 800 V and nominal currents up to 32 A, accommodating a wide range of electrical requirements.
  • ✅ Versatile Conductor Compatibility: These terminal blocks support various conductor types and sizes, providing flexibility in wiring configurations.
  • ✅ Integration with CLIPLINE Complete System: The PT Series is compatible with Phoenix Contact's CLIPLINE complete system, allowing for standardized bridging, marking, and testing accessories, which simplifies inventory management and enhances system modularity.
