Overview Models Resources Support

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.
