– Test disconnect terminal block URTK/SP
should be used for all measurement and
test work in the current transformer
secondary circuits
– The terminal blocks can be equipped with
fixed and switchable bridges on both sides
– Touch-proof test sockets with 4mm
diameter are already permanently
integrated
– The URTKD/SP can be used as a feed-
through terminal block of the same shape
without a disconnect function
– The URTK/SP test disconnect terminal
block and the SB2–URTK/SP 2-pos.
switching jumper can be used to perform
all switching tasks per current
