The following E300 Electronic Overload Relay sensing module catalog numbers
can be used with step down current transformers:
193-
ESM-IG-30A-E3T
193-ESM-IG-30A-T
193-ESM-IG-30A-P
193-ESM-I-30A-E3T
193-ESM-I-30A-T
193-ESM-I-30A-P
193-ESM-VIG-30A-CT
CT Primary (Parameter 263) and CT Secondary (Parameter 264) allows the user
to identify the turns ratio of the step down current transformers in use. The E300
Electronic Overload Relay will automatically adjust the measured current based
on these two configuration parameters. Users will use the primary current for
their FLA settings.
