General Duty—Up to 100 kA Short Circuit Current Rating

Class 3130

General Duty—Up To 100 kA Short Circuit Current Rating

D223N

General duty safety switches are designed for residential and commercial applications where durability and economy are prime considerations. Typical loads are lighting, air conditioning, and appliances. They are suitable for use as service equipment when equipped with a factory or field-installed neutral assembly or a field-installed service grounding kit, (see Equipment Grounding Kits) as applicable.

General duty safety switches are UL Listed, File E2875, and meet or exceed the NEMA Standard KS1. NEC 2023 404.30 protects against these units from being applied in any application, please obtain Heavy Duty Safety Switch if NEC 2023 compliance is required.

System equal or less than 10 kA SCCR — Any Brand of circuit breaker or fuse not exceeding the ampere rating of the switch may be used in conjunction with a non-fusible safety switch.

Systems above 10kA SCCR — The UL listed short circuit current rating for Square D non-fusible switches is based upon the switch being used in conjunction with fuses or Square D circuit breakers or Mag-Gard motor circuit protection

Footnotes

  1. Bolt-on hubs —Refer to Rainproof Bolt-On Hubs.
  2. When properly installed, the Class R Fuse Kit accepts only Class R fuses.
  3. Factory included to protect against inadvertent contact with live parts per UL 869A and NEC Service entrance barrier requirements.
  4. For corner grounded delta systems, use switching poles for ungrounded conductors. See data bulletin 2700DB0202 for additional information.
  5. For 200% neutral, order (1) additional neutral kit SN20A and (1) neutral jumper kit SN20NI.
  6. Order Class J Fuse Kit GDJK600 if using Class J fuses.
  7. If corner grounded delta system, use outer switching poles for ungrounded conductors.
  8. D325NT, D325NTR, D326NT, D326NTR, T327N and T327NR accept only 300Vac Class T fuses.
  9. Class R fuses are rated for 100 kA, however without the rejection fuse clips - system is limited to 10 kA since Class H or K fused could be installed in the future.
  10. Bolt-on hubs—Refer to Hubs.
  11. If a neutral assembly is required, order and field install SN0610.
  12. If a neutral assembly is required, order and field install a SN20A Neutral Assembly Kit. For a 200% neutral application, order and field install (2) SN20A Neutral Assembly Kits and (1) SN20NI Neutral Jumper Kit.
  13. If a neutral assembly is required, order and field install D600SN.
  14. Ampere rating of fuse or circuit breaker not to exceed switch ampere rating.
  15. Only applicable to DU324 and DU324RB. HD, JD = 25 kA maximum.
  16. SCCR = 50 kA, applicable to DU222RB, DU322 and DU322RB.
  17. Only applicable to DU323, DU323RB, DU325 and DU326.
