Overview
We offer a comprehensive range of plug-in installation terminals
for use in building management systems. We also offer a range
of compact, cost-effective terminal blocks with screw terminals
for connecting larger cross-sections.
Terminal blocks mounted on neutral busbars are most commonly
used in building management systems. In order to enable the
butt-mounting of different terminals, contact to the neutral bars
is always on the same mounting level. This means that 8WH1
screw terminals and 8WH4 plug-in terminals can be
combined as required and mounted on a single support rail.
The compact design of our neutral isolating terminals makes for
a neat and clearly arranged terminal strip. The neutral bar can
be connected over the terminal or over the contact separator of
the neutral isolating terminal. The neutral isolating terminal also
makes it easy to perform insulation measurements.
Note: Only Cu busbars must be used.
