PHOENIX CONTACT
Feed-through and PE terminal blocks
with 4 UDK... connections
– Two connection points on each side to
accommodate several conductors
– Double bridge shaft enables individual
potential distribution and supply
– Overall width 5.2mm or 6.2mm
– UDK3 and UDK4 are of the same shape
Ground terminal UDK ...-PE
– Same shape and pitch as the feed-through
terminal blocks
– The bridge ISSBI10–6 can be attached to
the neighboring UDK4 versions with
bridging facility thanks to the housing cut-
outs in the ground terminals
– Universal ground conductor foot for
mounting on NS35...- or NS32... DIN
rails (with the exception of
NS35/15–2,3)
CLIPPROJECTPlanning enables the
quick and convenient planning and
configuration of fault-free terminal strips.
