I had the same 'thermal limiter' (Siemens part no. 00152792, Z430KK6E

Netherlands (I'm also Dutch), as in the metal part of it is puched "KEMA
KEUR" which is the Dutch authority on certificates for electrical safety.
Under normal operation it's open. When overheated, it's shorted and will
switch on the fans.
So it is indeed a "crow bar".

No it is a simple thermal switch, very common.
