Abstract: A restoring element is for an electrical switch. In an embodiment, the restoring element is constructed in two parts from a first part and a second part. The two parts are configured to converge in a first direction for tripping the electrical switch and the two parts do not necessarily converge in a second direction for resetting the electrical switch, the second direction being different from the first direction. Further, the second part of the restoring element includes a restoring cam which is configured to interact with a handle of a switching mechanism of the electrical switch, such that, during resetting of the electrical switch, the restoring element is configured to be rotated by the handle in the second direction for resetting the electrical switch.

Abstract: A fuse arrangement includes a first safety fuse and a second safety fuse connected electrically in parallel with each other. The fuse arrangement also includes an end plate mechanically coupled to the first and second safety fuses to form a structural unit so that both safety fuses must be inserted/removed to/from an electrical power distribution installation at the same time. Furthermore, the electrical parallel connection of the two safety fuses, rather than a single relatively larger safety fuse, may allow the maximum current strength of an electrical power distribution installation to be maintained while the current is split between the two safety fuses so the size of the fuse arrangement may be reduced.

Abstract: A safety fuse arrangement may include at least a first safety fuse element and a second safety fuse element electrically connected to each other in parallel. The safety fuse arrangement further comprises a ceramic fuse body having at least a first locating space for locating and holding the first safety fuse element and a second locating space for locating and holding the second safety fuse element. The locating spaces are physically separated from each other by the fuse body. In this way, a compact safety fuse arrangement comprising a plurality of safety fuse elements which are electrically connected to each other in parallel can be realized as a structural unit that is inexpensive to manufacture and is suitable for higher rated currents.

Abstract: A fusible cut-out link, e.g., for semiconductor fuses, may have a ceramic body filled with compacted sand, wherein a supplementary body is introduced into the compacted sand. Said supplementary body may be embodied in such a way that an increase in internal pressure in the ceramic body due to thermal expansion of the compacted sand causes the supplemental body to release an additional volume into which the compacted sand is allowed to expand. In this manner, it may be possible to avoid or limit damage to the ceramic body due to stress fractures caused by the different rates of thermal expansion of the compacted sand and of the ceramic body as a result of an increase in temperature and the increase in internal pressure in the ceramic body associated therewith. The robustness of the fusible cut-out link may be significantly improved as a result.
