Breaker AIC rating

[Grouch]

The breaker in the link is by Siemens, catalog #BA120AFCHH. Just curious if the AIC rating is 65kaic. Also, what does the 'N/A' mean throughout the opening / top paragraph? such as N/A frequency rating, N/A phase.

I see 22KAIC in the description.
"...1-Pole AFCI Combo BAFH 22KAIC 120/240VAC are Circuit..."
The N/As, maybe in the UL details?

towards the end of the paragraph it also says 65kaic.

It appears that the thermal magnetic portion of the CB is 65, but the AFCI portion is not.

interesting... I didn't know a breaker could have 2 AIC ratings.

Neither did I.

There is only one set of contacts so they can only have one AIC rating.
The energy released internal to the breaker may destroy the AFCI circuitry if the fault current is greater than 22k, but that would be a SCCR not an AIC.

Time to look at the UL documentation instead of trusting a marketing person's technical understanding.

Thanks. Did not make sense otherwise.

Can't say how many times that thought has gone through my head when looking at kitchen appliance cutsheets ... call the manufacturer and talk to one of their tech people instead of reading the cutsheet.
