Panel SCCR = 3 kA (cannot exceed the lowest-rated component).
The power supply has 3 kA , which is lower than all others. short circuit current rating calculator
Yes. Replace the 3 kA power supply with a 10 kA version, or add a current-limiting fuse (e.g., Class J, 5 kA let-through) ahead of it. Using a fuse with a let-through of 3 kA or less allows the power supply’s rating to be increased per UL 508A SB. Panel SCCR = 3 kA (cannot exceed the lowest-rated component)
