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.
