You can solve many switching tasks clearly and affordably –
with the WTL 6/1 test-disconnect terminal, the
WTD 6/1 feed-through terminal, and the WTQ 6/1 cross-
disconnect terminal. This
guarantees that the measuring instrument not accidentally
disconnected. Apart from
that, load impedances lead measuring inaccuracies in
electricity supply meters and hence financial losses for
their operators.
The screws for connecting the conductors are only
accessible after the current transformer has been short-
circuited with the help the short-circuit slider.

Current transformers may only short-circuited operated
with negligible load impedance because open current
transformers “run hot” and destroy themselves
