The current capacity due to due to the difference in the load voltage
It is a conceptual reference case number, micro switch, toggle switch, relay (1 ~ 10A), etc.
Reference numbers is made 100% of the current capacity at the AC125V. And reference numbers is made 100% of the current capacity at the resistive load.
