It could be a thermal fuse, what kind of product is it on ?
Because if it's on one that generates a lot of heat, that's what it'd be, because if I remember correctly, a thermal fuse is used in order to keep a project that generates a lot of heat from melting itself. When it reaches critical temperature, the fuse melts, severing the connection and keeping the valuable parts intact.
Most likely it's on something rather old because heatsinks/microfans are now more in common use, and are now compact enough, and cheap enough to be of use unless it's a very small project like a miniature transformer, or a home made DC-AC inverter.
Also I think the second one is 55/95 Eg, or Eb, I can't really tell, it is rather blurry.
