A fuse element for a fuse with an integrated measurement function, includes a first receiving area in an embodiment, for receiving a melting conductor of the fuse, delimited in the length direction of the fuse by a closure element and in a direction orthogonal to the length direction by the fuse element. Further, in an embodiment, the fuse element has a second receiving area, physically separated from the first receiving area, for receiving a measuring device of the fuse. The second receiving area is designed to receive the measuring device in a wall section of the fuse element. The second receiving area formed in the fuse element protects the measuring device arranged therein against interfering environmental influences. The measuring device is used to ascertain the electric current flowing through the fuse directly on the fuse.

Fuse element and fuse

A fuse includes a protective housing and a measurement device. Two electrical connection elements of the fuse are routed out of the protective housing and at least one fuse element is arranged in the protective housing, the at least one fuse element electrically conductively connecting the two electrical connection elements in the protective housing to one another. The measurement device includes a sensor element to record a physical state measured value of the fuse and a transmission apparatus to transmit the measured value to a reception device arranged outside the fuse. The measurement device further includes a dedicated housing in which the sensor element is received and held, the dedicated housing being mechanically connected to the protective housing. An overall installation space required for the protective housing and the dedicated housing corresponds to an installation space of a standardized NH fuse. The fuse is usable for retrofit applications.

Fuse, fuse body, system and method

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.
