Cross-connections systems
Weidmüller can supply the cross-
connections WQV and ZQV fully
insulated against electric shock –
with various numbers poles (2- to
20-pole).24 1282250000 2012/2013
.
In addition the individual form, every
type terminal can also supplied
in the form 3-, and 5-pole blocks.
Protection against electric shock is
not provided the ends shortened
cross-connections.
All the blocks are permanently screwed
together and therefore guarantee
additional rigidity. Please note that the rated
voltage reduced when using cross-
connections.
The other advantages are:
• Constant force transfer through self
adjusting connection system
• Mounting any direction
• Electric shock protection (finger-
proof) German standard VBG 4,
also with cross-connections
• Extremely resistant distortion
Open cover and
remove screw
assembly.
Such cross-connections must used
with partition plates end plates in
order maintain the rated voltage.
Close cover and
tighten screw with
Allen key.
Insert conductor
and replace screw
assembly.
Leaf clamp conductor connection
for large cross-sections
It longer the case that conductors
with large cross-sections have be
forced into the clamping point.

they can now easily placed the
modular terminal. Terminal blocks can
be screwed directly mounting plates
with pitch.
Direct mounting possible thanks to
the elongated holes the underside
of the terminals
