Which Square D or Schneider Electric circuit breakers have SWD (Switch-Duty) ratings?

Product Line:
Circuit Breakers

Resolution:
Per UL 489, the switch-duty rating label (SWD) may be applied to one, two and three pole 15 A and 20 A circuit breakers, 347 Vac or less that pass the special SWD test requirements. The SWD rating applies to breakers used for regularly switching flourescent lights. While SWD may be applied to multiple-pole breakers, Schneider only offers the SWD rating on the single pole circuit breakers as listed below, and Powerpact H as noted at the bottom of the list.
