Wurth WR-TBL blocks launched by Wurth

The economical variant - the wire protector system - means that the screw is fastened in the terminal by the wire protection.

Due to this protection, the shearing and rejection of the wire are prevented.

In the rising clamp system the case moves up while fastening the screw and fixes it inside the terminal case, therefore a gas-tight and vibration-proof connection between wire and bus conductor is guaranteed.

The pluggable system grants easy mating and un-mating.

The cable strand is bolted together on one side and connected with the circuit board plug on the opposite side.

The screwless solution - the spring clamp system - works in a similar way to the rising clamp system.

The separation between mechanical and electrical function is also kept in the spring clamp system.

The spring clamp draws the wire against the electroplated copper bar.

Contact blocks from Wurth Elektronics have a current capacity up to 15A.

Due to this, all solutions are UL certified, most of them cULus and VDE certified.

According to UL and VDE specification, all WR-TBL products are branded with serial numbers and UL/VDE logos by Wurth Elektronik.

The PCB clamps are available with 2-8 pins and in the grid dimensions 3.5mm, 3.81mm, 5.00mm and 5.08mm.
