Z options
For some positions of the article number, a more detailed selection can be useful or necessary.
For example, when selecting a communication connection (position 9), the communications
module (PROFIBUS, PROFINET, etc.) must be dened.
This is done with the Z options that are appended to the article number. The number of Z
options depends on the individual conguration of the circuit breaker. No Z options are also
possible.
Z option rated current I
n
: Choice of rating plug
You can choose a rating plug that is below the rated current I
n
of the circuit breaker.
This is useful, for example, if the circuit breaker has already been chosen with a higher
rated operational current than is required for the existing installation with a view to future
expansion of the overall installation.
