how to say this sentence in Hebrew?
1. -how to say this in Hebrew?
	"Over-temperature, over-current, over-voltage protection" ??

Answer

חום יתר, זרם יתר, מגן מתח יתר

Answer

If your meaning is that the protection is of those things, it's not correct to say 
חום יתר, זרם יתר, מגן מתח יתר
because in this case you only refer to the 'over voltage' part, and not so correctly as well.
you should say
הגנה מפני חום יתר, מתח יתר וזרם יתר
