Technical Data
Current and Earth Current Measurement
Plug-in Connectors with Integrated Short-Circuiter
(Conventional Current Inputs)
Nominal currents: 1 A / 5 A
Max. measuring range: up to 40 x In (phase currents)
up to 25 x In (earth current
standard) up to 2.5 x In (earth current sensitive)
1)
Continuous loading capacity: Phase current/Earth current
4 x In/continuously Earth current sensitive
1)
2 x In/continuously
Overcurrent proof: Phase current/Earth current
30 x In/10 s
100 x In/1 s
250 x In/10 ms (1 half-wave) Earth current sensitive

Power consumption: Phase current inputs:
at In = 1 A S = 25 mVA
at In = 5 A S = 90 mVA
Earth current input:
at In = 1 A S = 25 mVA
at In = 5 A S = 90 mVA Sensitive earth
