Abstract: The present disclosure relates to a thermal trip compensation structure including a tripping bar having an ejector pin, a bimetal strip, a compensating component, a support for the compensating component, and an adjustment component. One end of the bimetal strip is connected with the support. The support receives and supports the compensating component. The adjustment component is capable of adjusting a position of the compensating component relative to the support. The compensating component has an inclined slant surface which is set in such a way that a gap between the inclined slant surface and the ejector pin of the tripping bar when the bimetal strip is deflected after the occurrence of short circuit is less than the gap between the inclined slant surface and the ejector pin of the tripping bar when the bimetal strip is not deflected before the occurrence of the short circuit.

Abstract: An overload protection device is disclosed, characterized in that, the overload protection device comprises a first heating band (i.e., a terminal); a second heating band; a bimetallic strip; a litzendraht wire; a lower part of the first heating band and a lower part of the bimetallic strip are mechanically connected with each other; two ends of the litzendraht wire mechanically connect with an upper part of the second heating band and an upper part of the bimetallic strip respectively.
