UMG 96RM-EL
Voltage metering
The UMG 96RM-EL can be used for voltage measurement
in TN, TT and IT systems.
Voltage measurement in the UMG 96RM-EL is designed
for the 300 V overvoltage category CATIII (4 kV rated
pulse voltage).

In systems without a neutral, measured values that
require a neutral refer to a calculated neutral.
