Agreed. The contacts in a NEMA contactor are probably designed with
a safety factor of 2, and after looking at closer, AB is calling it a
size 0 switch which, if it is like their contactor counterparts, is
rated at 18 amps continuous.
I just hate to go on the record telling someone its O.K. to exceed
power ratings on a switch. I guess if it feels hot turn it off ;)
You are right about IEC contactors, though I have more problems with
the coils burning out/melting down or buzzing. Especially the import
stuff people are using in industrial equipment nowdays.
