Apart from
that, load impedances lead measuring inaccuracies in
electricity supply meters and hence financial losses for
their operators.Testing made easy
WTL 6/1, WTD 6/1, WTQ 6/1
Sliding disconnector easy use (WTL 6/1)
One short-circuit slider per terminal (WTL 6/1)
Current transformers may only short-circuited operated
with negligible load impedance because open current
transformers “run hot” and destroy themselves. This
guarantees that the measuring instrument not accidentally
disconnected.
One short-circuit jumper per terminal (WTQ 6/1)
Safe disconnection cross-connection (WTQ 6/1)

The screws for connecting the conductors are only
accessible after the current transformer has been short-
circuited with the help the short-circuit slider.64 1282250000 2012/2013

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
