3 Phase power supply in FLA Calc.

[BN32]

Let me start by saying I’m not an engineer and I haven’t been doing this very long. I’m doing an FLA calc for my UL 508A label. I’ve added up my loads in the power circuit. Motors, transformer, etc. I have a couple of 3 phase power supplies that I’m not sure on how to calculate their FLA. Both power supplies are protected by 2 amp fuses. Is it safe to just use the 2 amp fuse rating? Any feedback would be helpful. Thanks.

You don't know the watt capacity of the power supplies? How do you know if they will handle the load?

I’m just making the UL label. I’m only documenting the FLA. This is the power supply. https://mall.industry.siemens.com/mall/en/WW/Catalog/Product/6EP1436-2BA10
