PowerPacT™ H- and J-Frame Circuit Breaker Enclosures

The enclosures' maximum short circuit ratings are 25 kAIR at 600 Vac, 65 kAIR at 480 Vac, 125 kAIR at 240 Vac and 20 kA at 250 Vdc unless otherwise noted. Enclosures accept 100% rated circuit breakers [2]. The enclosures are not compatible with earth-leakage or ground-fault modules.

H- and J-frame circuit breakers with MicroLogic trip units can be used with these enclosures, but have the following limitations:

  • No communication accessories can be mounted in the enclosure (no IFM or Front Display Module, IFE, etc).

  • The trip unit will not be accessible or visible without the removal of the cover (except J250F and J250S).

  • For LSIG, there is no room for the NCT to mount in the enclosure.

Enclosures for Special Applications


Hazardous Locations: NEMA 7 And NEMA 9 Circuit Breaker Enclosures

The NEMA 7 and 9 enclosures are cULus listed unless otherwise noted. They are rated for use in hazardous locations as defined in NEC Article 500. The short circuit current rating of the enclosed circuit breakers is equal to the rating of the circuit breaker installed unless otherwise noted. They are suitable for use as service entrance equipment when neutral is installed. Enclosures require the use of 75°C copper wire only. The NEMA 7 enclosures are suitable for rainproof applications when the included PKDB1 breather and drain kit is installed.

Footnotes

  1. For NEMA 3R applications, remove drain scerw from bottom end well.
  2. Use only 90°C (minimum) rated wire sized per ampacity of 75°C rated conductors for 100% rated circuit breakers.
  3. Rated for 240 Vac maximum. Short circuit current rating is 25 kAIR at 240 Vac.
  4. Accepts standard 80% rated circuit breakers only. Not rated for 100% rated circuit breakers.
  5. Use copper conductors only.
  6. Rated 480 Vac maximum. Short circuit current rating is 18 kAIR at 480 V.
  7. For conduit entry through the top end wall use one of the following Square D conduit hubs: A200L for 2.00 in., A250L for 2.50 in., A300L for 3.00 in., A350L for 3.50 in. or A400L for 4.00 in.
  8. Add suffix BE if no knockouts are required on the end walls.
  9. For access to the circuit breaker’s standard, ammeter or energy trip unit panel/LCD, add suffix T.
  10. For 200% neutral use copper wire only.
  11. Complete rating is NEMA 3, 3R, 4, 4X, 5, and 12.
  12. For NEMA 3R applications, remove drain screw from bottom endwall.
  13. Add suffix VW for visibility to the standard, ammeter or energy trip unit of the PowerPact circuit breaker.
  14. Will accept PowerPacT L-frame circuit breakers and Motor Protectors with suffixes M38X
  15. Will accept PowerPacT L-frame Molded Case Switches.
  16. When the QJL circuit breaker is installed in the enclosure, the enclosure is limited to Short Circuit Current ratings of 65 kAIR at 240 V and 100 kAIR at 208 V.
  17. Limited to 200 A.
  18. Order current transformer kit S33576 seperately.
  19. Current transformers applicable only on PowerPacT P circuit breakers. Current limitations are 400–800 A and 400–1200 A respectively for the M800 and P1200 family of enclosures.
  20. Use 500 Vdc or 250 Vdc rated circuit breakers only.
  21. Enclosures are provided with the Handle Padlock Attachment (HPALM) for field installation to lock the circuit breaker in the “ON” or “OFF” positions.
  22. Maximum short circuit and voltage is 30 kAIR at 480 Vac.
  23. LAL or LHL circuit breakers with an MB or MT suffix are not compatible with these enclosures: LA400DS, LA400AWK, and LA400LS.
  24. Enclosure cover has an integral padlock provision to provide a means to lock the circuit breaker in the “ON” or “OFF” position.
  25. NEMA 7 — Indoor Hazardous Locations — Division 1 and 2, Class I, Groups C and D; Class II, Groups E, F and G; Class III
  26. NEMA 9 — Indoor Hazardous Locations — Division 1 and 2, Class ii, Groups E, F and G; Class iii
  27. Short circuit current rating: 65 kAIR at 240 Vac, 25 kAIR at 480 Vac, and 18 kAIR at 600 Vac
  28. Not cULus listed due to wire bending space.
