Condition

LJL36400U31X trip-unit correction: Square D LJL36400U31X is a 400-amp, three-pole PowerPacT L-frame breaker equipped with a MicroLogic 3.3 electronic trip unit. Schneider lists 25kA interrupting capacity at 600 volts; this is not a 65kA thermal-magnetic bolt-on model.

LJL36400U31X specifications

  • Catalog number: LJL36400U31X
  • Rating: 400A, 3-pole, 600VAC
  • Interrupting capacity: 25kA at 600VAC
  • Trip unit: MicroLogic 3.3 electronic
  • Terminations: Lugs
  • Continuous rating: 80%

The U31X suffix is functional

The suffix identifies the installed trip package and options. Another 400-amp L-frame can have different protection functions, terminals, rating, or accessory wiring even when the frame looks the same.

Engineering and commissioning

Verify the complete suffix, voltage-specific AIC, trip settings, lugs, accessories, mounting, and coordination study. A qualified professional should install and commission the breaker using Schneider procedures.

There is a $15 charge for delivery. Additional charges will be imposed by our couriers for delivery to remote areas, a surcharge may be levied to cover carriage to these areas.
