Definitions

phase transition materials can be used which melt at a relatively low temperature, that is to say show a solid-liquid phase transition.
Melting materials in microencapsulated form are preferably used, since otherwise there is a risk that the melting of the material will cause irreversible changes in the resistance body. Such materials are offered, for example, by Triangle Research and Development Corporation. Phase transition materials are preferably used, the heat of transformation of which is relatively large, e.g. B. is at least 40 J / cm 3 .
the phase transition causes the second Filler especially in a certain overcurrent range a noticeable increase in the response time of the Protective element.
a motor protection circuit are used, as can be seen in Fig. 1.
the motor protection circuit 2 contains a protective element 4 according to the invention and one Switch 5, which after any response of the Protection element 4 is opened.
