Figure 7 Current transformer connection
As single wires, solid conductors as well as stranded conductors with con-
ductor sleeves can be used. Up to two single wires with identical cross-
sections can be used per connection.
Alternatively, short circuit links (Order no. C53207-A406-D193-1) can be
used for vertically arranged terminal points. If short circuit links are used,
only ring lugs are permitted.
When connecting single wires, the following cross-sections are allowed::
Wire cross-section:
Conductor sleeve with plastic sleeve
Stripping length:
(when used without conductor sleeve)
Mechanical Requirements
The fixing elements and the connected components are designed for the
following mechanical requirements:
Permissible tightening torque at the terminal
screw
Permissible traction per connected conduc-
tor
