Weidmüller‘s tension clamp terminals
have three supply terminals:
ZEI for standard terminals
ZEI 16-2/1 for Roof-Style terminals

The current distributed across any
number terminals simply plugging
the cross-connection into the middle of
the terminals. The unit released from the
terminal simply pressing the release

An end bracket fitted the

terminals ensure that they sit firmly
in position. The conductors are connected
in the tension clamp terminals with
standard screwdrivers, shown
in chapter alternative to
screwdrivers, fully insulated operating
tools are also available; see page

The marking surface the end bracket
can also used for group marking.
A plug-in cross-connection system
(ZQV) available for all Z-Series
terminals.
Weidmüller‘s identification systems in
chapter are used mark tension
clamp terminals.
The slot-in test adapter (ZTA) used
as single unit and test adapter
strip for voltage measurement in
control cabinets.
Further helpful accessories are
available for terminals using tension
clamp technology, such as:
• Pluggable extra connections (ZZA)
• Housings for installation of
electronic components (ZBS 1)
• Pluggable fuse holder
(SIHA SIHA 3)
• Terminals various colours. Individual terminals,
terminal groups and conductors can be
marked. simply
