IEG 45-3LA/400/21

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.
