Description of system components
8.5 Current / voltage measuring modules (UM, UM+) for the SIMOCODE pro V High Performance device series
SIMOCODE pro
138 System Manual, 05/2019, A5E40507475002A/RS-AD/004
● Average phase current - mean value (I1/I2/I3) I_avg: 1.5%
● Ground-fault detection according to IEC 60947-1:
– in the range 30% - 120% I
e
: ± 10% (Class CI-A)
– in the range 15% - 30% I
e
: ± 25% (Class CI-B)
The measurement ranges of the current / voltage measuring modules have been adjusted to
the current ranges of SIRIUS Innovations contactors and load feeders. This results in
increases to the following measuring ranges: 0.3 to 4 A; 3 to 40 A and 10 to 115 A.
The measured values with the accuracy figures mentioned can be found in data record 94 -
Measured values (from byte position 132) and in data record 95 - Statistics data in the
manual SIMOCODE pro - Communication
