I thought; so what, current is current, right? Wrong. The breaker in
an ET is a bimetallic strip. It works by heating the strip to a given
temperature. Current? Well, the TEMPERATURE is related to the POWER
(current x voltage) and time. Guess what?
Yes, but the voltage here is the drop across the breaker (less than a
volt), not the voltage of the battery or the load. Therefore very little
change in rating with voltage.
