accessible after the current transformer has been short-
circuited with the help the short-circuit slider.8/IH/BL WTL6/1

Current transformers may only short-circuited operated
with negligible load impedance because open current
transformers “run hot” and destroy themselves.
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 EN
cross-disconnect terminal.6/45 SW
