) Current and voltage data for quick connect terminations
according to EN 61210 are also dependent on nominal size,
material, insulation of the coupling and conductor cross section.
UVKB terminal blocks
– The front flat plug connection is the
optimum wiring design for tight spaces
and if cable ducts need moving close to
the terminal strip
– The housing walls only protrude slightly
beyond the metal parts because it is
assumed that fully-isolated plug-in sleeves
are connected
– The slotted plugs allow a fully isolated or
two bare 2.8 mm plug-in sleeves to be slid
on in place of one 6.3 mm flat plug-in
sleeve
UHK terminal blocks
Owing to the characteristic arrangement
of three slip-on blade connectors on each
terminal block side, UHK... terminal blocks
prove to be advantageous in technical
applications:
– Economical use of terminal blocks and
bridge connections
– Convenient operation, i. e., free view of
the connectors, good connector
accessibility and quick connection check
– The marking is easily visible due to the
smart wire guiding in the lateral cable
ducts
– Reading the marking from the front
