Manual, 11/2017, L1V30499596002-01
Two individual series of electronic trip units
Exchanging rating plugs
The rating plugs can be exchanged on the front of all electronic trip units. With this option of
exchanging the rating plug, the current rating can be adapted to a changed situation of the
overall installation. This function is suitable for installations for which further development is
planned or in cases, in which the power export could be temporarily limited (e.g. mobile
generator set).
The overload protection function (LT) can be deactivated at any time if the "L off" rating plug
version is used.
For residual-current protection with a suitable summation current transformer, there are
rating plugs with a residual-current (Rc) protection function.
