Disconnect Terminals with Screw (Clamping Yoke) Connection Technology
WTR 2.5
NEW
Disconnect test terminals are specially designed
for test and measurement tasks. Electrical circuits
can be disconnected from the supply by means
of their disconnect lever: an advantage for quick
troubleshooting.
The new WTR terminals are now equipped with
even more functionalities. The disconnect lever
area allows you to carry out the disconnection by
means of either the lever or a pull pin (TNST).
ZQV 2.5N pluggable cross-connections enable
time and cost-saving feed-through of potentials
to adjacent terminals. System accessories
increase the range of possible applications: for
example the fuse holder SIHA is all that is needed
to create a fuse terminal. The component plug
holder (BEST) converts the WTR into a component
terminal. The integrated test point for 2.3 mm test
plugs guarantee continued readings of potentials.
