Technical data
All technical specifications apply to "3-phase 4-wire system with earthed neutral conductor", unless
explicitly stated otherwise.
Full scale value of the measuring range of the neutral conductor current
The full scale value of the measuring range of the neutral conductor current always corresponds to
the maximum current of the terminal (EL3413 = 5 A and EL3433 = 10 A) and cannot be switched.

Notices on analog specifications

Beckhoff I/O devices (terminals, boxes, modules) with analog inputs are characterized by a number of
technical characteristic data; refer to the technical data in the respective documents.
Some explanations are given below for the correct interpretation of these characteristic data.
