Data sheet
1Description
Correct invoicing on the basis of a measuring instrument
can only be ensured if the three phases L1, L2, and L3 are
available.
IEG 45-3LA/400/21 voltage indication modules are used for
monitoring, for example, on a tariff changing board. These
modules indicate all three phases with high-accuracy
reading, even in case of reverse voltages.
These modules also have a floating PDT contact, thereby
offering the convenience of voltage monitoring through
remote querying.
