ABB’s IM300 documentation covers dedicated voltage and current instruments as well as multifunction power-monitoring models. This page uses ABB’s English operation manual to distinguish IM300-U, IM300-I, IM301, IM302 and IM303 for model identification and enquiry preparation.
Dedicated Measurement or Multifunction Monitoring
IM300-U & IM300-I
IM300-U focuses on voltage and frequency. IM300-I focuses on current and zero-sequence current. Their measurement scope differs from the multifunction IM301–IM303 models.
IM301, IM302 & IM303
IM301 covers basic electrical parameters, power and energy. IM302 adds functions including unbalance, demand, alarms and individual harmonics up to the 15th. IM303 extends the documented range with tariff statistics, extrema and individual harmonics up to the 31st. Check the complete function matrix for the required I/O and measurement configuration.
Check the Existing Installation
Match the complete model designation, current input, auxiliary supply, wiring system, panel dimensions and required outputs to ABB’s manual and the instrument nameplate. The manual lists RS485 communication for the referenced models. Similar front panels or names do not establish electrical or mechanical interchangeability.
For another panel-monitoring range, see ABB M1M Multimeters & Power Meters. Any change of instrument requires a separate installation check.
ABB IM300 Model Reference
These five model names and function distinctions are documented in ABB’s operation manual. Use the instrument nameplate for the complete ordering identification; this table does not assign unverified article numbers.
