Footnotes

  1. Circuit breakers with J, L, and R interrupting ratings are UL certified as current limiting.
  2. See Supplemental Digest Section 3 for circuit breakers with field interchangeable trip units.
  3. For applications requiring communications see Micrologic™ Trip Unit Accessories .
  4. 3P circuit breakers with this trip unit can be used for 2P applications.
  5. AL400L61K3 terminal wire ranges are (1) 2 AWG–600 kcmil Cu or 1) 2 AWG–500 kcmil Al.
  6. AL600LS52K3 terminal wire range is (2) 2/0 AWG–500 kcmil Al/Cu.
  7. Fixed ST and LT delays.
  8. 3P circuit breakers with this trip unit can be used for 2P applications in order to have ground fault protection. Additional metering capabilities will not work properly on the unconnected phase.
