Protecting a UPS

[alixenos]

Hello,

I have a 150 KVA UPS and I need to protect it with two OCPD per the manufacturer recommendation.

The output of the UPS is recommended to be protected with 300A breaker which to me exceeds even the 125% of the current rating!

Why is that?

You might be looking at the wrong kVA size or voltage in the planning guide. Paste a link for what you are looking for.
