Availability of option
This option is available for the following S120 Cabinet Modules:
● Line Connection Modules
Description
If current transformers are used for measuring or monitoring purposes, they are installed in
the Line Connection Modules with option L41. The current transformers are installed
upstream of the main breaker in all three line phases of the infeed.
The transformers have an accuracy class of 1.0. The secondary current is 1 A maximum.
The measuring connections for the current transformers are routed in the Line Connection
Module to terminal block -X60.
Transformation ratio of the current transformer in the Line Connection Module
The assignment of the order numbers of the Line Connection Modules to the transformation
ratios of the current transformers is shown in the following table.
