DMA-3 CT TrueRMS

Current intensity indicator,

3-phase

The DMA-3 CT is a 3-phase current intensity indicator, adapted 

for measurement in an indirect circuit using current transfor-

mers with an output current of 5 A. 

The sensor correctly measures the true rms value of the 

current (TrueRMS), even in the case of a distorted (de-

formed) current waveform.

The indicator continuously measures the RMS current value, the 

result of which is shown on a 3-row, 3-digit segment display on 

the facade of the unit. 

The indicator allows the value of connected current transfor-

mers to be set, so that the value shown on the display corre-

sponds to the actual current value. 

The DMA-3 CT is suitable for mounting in a switchgear directly 

on a 35 mm DIN rail.
