Solid State *The above frame sizes are also available with solid state trip units, add a prefix of "S" to the catalog type.

  1. 100% rated BKRS.Ý Available in most sizes from 400A frame up to 3000A frames.Ý 400 & 600A frames use CU. wire only.
  2. Single pole breakers can be group mounted 6 to a 3 3/4" space.
  3. DC ratings, 125V for 1pole BKRS, 250V for 2 pole breakers, 500V for 3 pole breakers connected with 2 poles in series.
  4. Trip types, NI = non-interchangeable, IT = interchangeable trip, ADJ = sold state adjustable.Ý All "IT" type breakers are available as non-interchangeable trip type, insert an "X" before the ìD" in the catalog no.
  5. Type "C" current limiting circuit breakers are fuseless type and are non-interchangeable trip.
