Socket Type StB 25 accepts test plug PS 4 in Type WTL
6/1 disconnect terminals or Type QS cross-connection
plugs. The Type StB 35 is used to simultaneous testing
with inserted cross-connection slides (QVS).
Current transformers must always have a
closed secondary circuit, even when the
exchanging measuring instruments or
electricity meters and when carrying out
reference measurements with external
measuring instruments.
Various easy and clear wiring solutions
can be found using lateral disconnect
terminals WTL 6/1, feed-through terminals
WTD 6/1 and cross-disconnect terminals
WTQ 6/1.
Examples:
Simple current transformer circuits
Measurement transformer test sets
With one basic version, the WTL 6/2 can
fulfill all circuit tasks occurring in practice
as a lateral disconnect terminal. The short-
circuit slides are of shock-proof design.
Two short circuit slides can be installed.
The WTL 6/3 is identical in function with
the WTL 6/2 and is suitable for safety plug
use due to its test socket StB 19.1 which
is safe from finger touch.
