Footnotes

  1. See Supplemental Digest Section 3 for circuit breakers with field-interchangeable trip units.
  2. DC not available with electronic trip units.
  3. The LSI with 3.2S/3.3S trip units have fixed short time and long time delays.
  4. Requires neutral current transformer on the three-phase four-wire loads.
  5. ZSI for H/J frames in only OUT. for L-frame ZSI is In and OUT.
  6. Indication available using the communication system only.
  7. % of hours in 4 current ranges: 0–49%, 50–79%, 80–89%, and >90% In.
