I need some advices on a design and not values in datasheet.
I know that the carry current is the current that can be supplied continuously to contacts without exceeding the maximum temperature when the contact are not switching.
- how can I be sur that contact parts of the relay won't melt or stick together?
- how can I calculate the real temperature at the contact?
- Is the maximum current in a material only determined by Joule losses?
- How can I calculate the maximum switching current possible.
Can someone please gives me some explanations?
