Rating Plug
The Rating Plug defines the rated current I
n
within a certain range for a given circuit breaker frame size.
If a rating plug with a higher current than the maximum permissible circuit breaker rated continuous current is plugged in, the electronic
system of the trip unit recognizes this error and signals it with a flashing T.U. ERROR indicator.
The trip unit ignores the rated current value specified by the incorrect Rating Plug and sets it to the value of the smallest Rating Plug for the
frame size of the relevant circuit breaker.
The same happens if a circuit breaker with frame size III is equipped with a Rating Plug smaller than 800 A.
All set protection parameters are adjusted accordingly.
It is not permitted to operate the trip unit without a Rating Plug. If a circuit breaker is nevertheless started up without a Rating Plug,
the T.U. ERROR indicator will light up and the trip unit settings will default to the lowest possible settings for that frame rating.
