Abstract: A fuse with two spaced apart power supply connections, consists of identical arrays of active portions comprising moldings and planar intermediate layer between moldings. A fuse has two spaced-apart power supply connections and an active part which comprises a fusible current-carrying fuse element and an arc-extinguishing medium. The fuse element is of modular construction and has at least two first modules connected in series and is connected to the two power supply connection. The fuse element is arranged on an electrically insulating substrate in which the arc-extinguishing medium covers the exposed surfaces of the fuse element. The active part is formed as a sandwich and has two stable moldings, and has a predominantly planar intermediate layer arranged between the two moldings. The intermediate layer contains at least the two series-connected first modules. A first molding of the two moldings is formed at least by part of the electrically insulating substrate, and a second molding is formed at least in part by the arc-extinguishing medium.
