455 PHOENIX CONTACT
– The USST... terminal blocks were
developed especially for use in the energy
supply sector
– When combined with hook-type cable
lugs, the spring-assisted screw terminal
blocks optimally meet the technical
requirements of ENATS50-18
– Universal foot for mounting on NS32 and
or NS35 DIN rails
– The bridge bar isolator switching jumpers
ISSBI... enable switchable cross
connections with IS-K... . The screw
functions as a current-carrying switching
element
– Large marking option of every terminal
point
Space-saving conductor connection
The flat-ribbon cable lugs with
C-BCI ... SO hooks enable vertical crimping
(see figure below), which means that
conductors in the nominal cross-section
can be wired without loss of pitch in a way
that saves space. Further information about
flat-ribbon cable lugs with hooks can be
found at phoenixcontact.net/products.
