why common mode inductors burn / Break in power supplies board?

The current flowing through them or the heat dissipated in them is more than they can withstand?

That would do it! I've seen this several times myself.

The inductors are catalogued by their thickness TW - AWG. Example the cable: 110 volts, this consumes 13 amperes is 2 HP, 1,5 Kw, Cos X 0,83, fuse 20 amperes, caliber of conductor TW 12 AWG, resistance to 20 ºC 5,211 ohm/km. If the cable has a tension of 110 volts and one resistance by 5.211 kilometer of ohm, it gives by I=V/R… I=110/5,211=21 Amp max, >21 Amp (it begins to warm up), if it is increased, the cable it leaves smoke to him, the insulator is burned and they broken (over it passes the temperature of fusion of the thickness of the cable).

The factual distinction in general terms between electrical and electronic engineering seems to be the size the currents used!

V/r,

To which Inductor you call "common mode inductors"
