ABSTRACT:
The invention relates to an electric fuse with a fuse element located in a housing which encases a fuse element chamber. The fuse element melts and thus cuts out the fuse under an overcharge, whereby the temperature and pressure in the interior of the casing will abruptly rise. The housing is provided with a pressure relief means through which at least part of the gas volume can be let off to the outside to prevent the housing from destruction if high internal pressure peak values occur on cutting out the fuse.
