Measurement categories
The MX403B is designed for applications in measure
ment categories CAT II and CAT III:
CAT II
Measurement category II is applicable to test and mea
suring circuits that are directly connected to the user con
nections (sockets) of the low-voltage grid installation. It is
expected that this part of the installation will have at least
three levels with overload protection elements between
the transformer and the measuring circuit connection
point.
CAT III
Measurement category CAT III is applicable to test and
measuring circuits that are connected to the distribution
circuit of the building low-voltage grid installation. It is
expected that this part of the installation will have at least
two levels with overload protection elements between the
transformer and the measuring circuit connection point.
