Terminal blocks

XB IEC terminal blocks

Versatility, quality and reliability

Eaton’s robust line of XB IEC terminal blocks are designed for prolonged life under harsh conditions. This comprehensive portfolio comes complete with universal accessories across three connection technologies – screw, spring cage and insulation displacement connection (IDC) – reducing inventory and logistic costs. With space savings in mind, the terminal blocks are small, adjustable and provide maximum flexibility and easy installation. 

Core features of XB IEC terminal blocks

  • High-grade, strain-crack and corrosion-proof copper alloys to prevent electrolytic corrosion and rusting
  • Screw locking maintenance-free design ensures proper operation and prevents screws from backing out, so tightening of the terminal screws is not necessary
  • Metal surfaces are protected with a lead-free, galvanic nickel or tin plating. As a result, the electrical conductors’ temperature remains cool
  • Copper wires can be clamped without pre-treatment or ferrules can be used for splicing protection. Multiple conductors can be connected in the same clamping mechanism, saving space
  • Spring cage connection system for applications that are sensitive to vibration exerts a constant force on the wire, resulting in a vibration-proof, gas-tight connection
  • Front connection design allows the screwdriver and wire to enter from the same direction, providing easy wiring in tight spaces
  • Nylon construction of modular terminal blocks provides anti-tracking and impact resistance

The options you need when you need them.

Hybrid terminal blocks offer the best of both worlds with IDC or spring cage technology on one side and a universal screw connection on the other, giving you the options you need, while common profiles and accessories help keep your business efficient.

Universal screw terminal connection

XB screw type terminal blocks, catalog prefix XBUT, fit most applications. The technology features a multi-conductor connection and maximum contact forces. The style combines the advantages of a screw connection system with the benefit of spring-loaded contacts. The snap-fit ground (PE) terminal block and standard plug-in bridges allow for critical time savings when assembling terminal strips.

XBUT Available Product

  • Feed-through terminal blocks
  • 2-, 3- and 4-conductor modular terminal blocks
  • Multiple level terminal blocks
  • Knife disconnect terminals
  • Fuse terminal blocks
  • Disconnect and component terminal blocks
  • Diode terminal blocks
  • Wide variety of available accessories

Spring cage terminal connection

Featuring a smaller spring technology, the spring cage terminal style saves significant space without giving up large surface marking and generous wire entrance, as well as its flexible push-in bridging system. XB spring cage terminal blocks are available for rated conductor cross sections of 1.5–35 mm2.

XBPT Available Product

  • Feed-through terminal blocks
  • 2-, 3- and 4-conductor modular terminal blocks
  • 3-conductor hybrid modular terminal blocks
  • (spring cage to screw terminals)
  • Double-level terminal blocks
  • Double-level 3-conductor terminal blocks
  • Three-level terminal blocks
  • Disconnect terminal blocks
  • Fuse terminal blocks
  • Diode terminal blocks
  • Pluggable terminal blocks for disconnect, fuse and component plugs
  • Wide variety of available accessories

Insulation displacement connection (IDC)

Designed for critical time-saving applications. Connect the conductor without having to strip it first—amounting to up to a 60% time savings. With the insulation displacement contact, this style of terminal block ensures a reliable electrical connection with a simple, audible click.

The IDC style of XB terminal blocks is also available in a hybrid version, with the fast, time-saving IDC connection for wiring in the control cabinet and screw terminals for field wiring of the conductors that come from outside. The hybrid version allows you to profit from the fast IDC connection and still offer your customers their preferred connection system.

XBQT Available Product

  • 2-, 3- and 4-conductor modular terminal blocks
  • Double-level modular terminal blocks
  • Disconnect terminal blocks
  • Disconnect, fuse and component plugs
  • Hybrid terminal blocks with screw connections
  • Wide variety of available accessories
