1. Terminal Strip Safety Termination
Applied to the final block in a WDK 2.5 double-deck assembly to cover exposed metal components.
Problem Solved
Eliminates shock hazards by covering the open side of the last terminal block, ensuring IP20 finger-safe protection for maintenance personnel.

2. Electrical Clearance and Creepage Extension
Inserted between terminal blocks of different potentials or functional groups on the same DIN rail.
Problem Solved
Prevents electrical arcing and short circuits by physically increasing the creepage and clearance distances between distinct voltage groups.

3. Mechanical Assembly Stabilization
Mechanically seals the open face of WDK 2.5 blocks to prevent contaminant ingress and structural misalignment.
Problem Solved
Protects internal busbars from conductive dust accumulation and reinforces the mechanical rigidity of the terminal block row against vibration.
