I need any information about right value of thermal fuse in steam generator?

Could You give me any information about right value of thermal fuse in steam generator of SRG 120 Proffesional iron or similar?
There is a picture of steam generator (the thermal fuse is at the bottom from the left - 2 white wires):

The sign of it is illegible, but I suppose it has probably value of temperature = 72 Celsius or 228 Celsius (symbol TZ D-072 or TZ D-228), for example:

Help me, please!
