Overload on ATS (Automatic Transfer Switch)

This was originally posted on APC forums on 8/29/2013


Does somebody know what happens if my ATS (AP7721) exceedes the 10A (Europe, 230V) maximum corrent limit?

Reading specifications, it has no overload protection.

So, after some amount of time in overload, may it brake itself?

Thanks in advance.

It would alert you about an overload from the network management card in the ATS and front LCD display and then it'd rely on upstream protection (like a circuit breaker) at your electrical panel. That should be sized appropriately according to what you see in this document -> http://www.apcmedia.com/salestools/ASTE-6Z6KBC/ASTE-6Z6KBC_R4_EN.pdf which says external protection recommended, 16A.
