Accumulating and isolating the neutral potential
• Combining the neutral conductors of the individual circuits
through the neutral busbar up to a current load of 140 A.
• Connection of the busbar’s neutral potential to the
ground-fault circuit interrupter or supply for the distribution
unit with connector clamp WAK in 16 or 35 mm 2 .
• Safe and stable 3D positioning of the neutral busbar
through busbar support with end clamping function.
Jumpering the terminal blocks
• Touchproof jumpering with insulated cross connector.
• Flexible potential distribution with double jumpering
channel and releasable links.
• High resistance of the cross connectors to the “rated
current” of the rated cross section.
• High resistance to mechanical wear.
– Due to a separation of the mechanical and electrical
functions
– Protection against excessive bending of the contact
spring due to its structural design
Marking live potentials
• Marking of live components for greater safety.
• For terminal blocks that remain live when the main switch
is disconnected (DIN VDE 0113).
• The snap-on cover can only be removed with a tool.
Clearly marking all clamping points
• Marking tags easily readable even with the wires
connected.
• Clear assignment of wire to clamping point during wiring.
• Simplified troubleshooting for servicing.
• Individual marking with the wiemarc and wieplot
marking systems.
Selection of high-quality materials
• Special alloys enable low contact resistance and provide a
gas-tight contact area:
-– Clamping spring: stainless CrNi steel
-– Busbar: tin-plated copper
• Polyamide has excellent electrical, chemical and
mechanical characteristics:
– Temperature resistance: up to 120 °C
– Creepage resistance: CTI 600
– Flammability class: self-extinguishing, UL94-V0
