- the preferably hollow-cylindrical insert in each case with one of its end faces, is in contact with one main electrode in each case.
- the flashover between the main electrodes takes place only after a relatively longer period of time or at very high pulse currents, which is particularly of interest if the Restspannu ng the spark gap should be at a plurality of pulse-shaped discharges above the rated voltage to a Netzbeckstrom prevention.

- the mechanical release can be embodied as a wire-shaped release part, whereby preferably this wire of the release part is connected in parallel over a part of the entire overcurrent protection device, which has the advantage that the coordination of the current commutation and the switching capacity is limited to this part of the protection.
- the fusible link of the fuse to which the indicator is connected in parallel may be provided with a minimally lower melt temperature to ensure a safe indication even at low overloads.
- the indicator part i. H. the parallel connection, provided with an additional housing 700 (see FIGS. 8 and 9).
- This housing 700 blocks the external flashover and greatly reduces the danger that can arise from released indicator parts (striker).
- the housing 700 is preferably arranged at right angles to the longitudinal axis of the wiring substrate 800.
- the first part of the series assembly 900 comprising the connection cylinder and protective cover individual fuses, is located on the underside of the wiring substrate 800, with the second part of the series assembly located in the housing 700 being placed on top of the wiring substrate 800.
- the wiring carrier 800 has an elongated, rectangular shape with screw connection lugs 110 attached to the narrow sides, wherein the first part of the series assembly 900 is located at a longitudinal outer edge, substantially laterally terminating therewith.
- the protective housing 700 is open to the longitudinal edge of the Verd rahtu ngslvess 800 to allow escape of the firing pin therein and an operative connection to a spring-biased indicator slide 111.
- the protective housing 700 has on its side facing away from the wiring substrate 800 top a color-coded indicator surface, for. B. red, or has an indicator surface extension, which extends from the housing 700 starting.
- the wiring carrier 800 is mountable on top of a housing 112, wherein the housing 112 may be a series spark gap arrangement.
- Sheathed portions are the top of the wiring substrate 800, the groove-shaped recess 114, the spark gap housing 112 and the fuse housing 700 to see.
- the area of the carrier board and the fuses is protected from the spark gap housing 112 by an insulating partition plate from staining or contamination from this area.
- the fuse in the groove-shaped recess 114 is thus, in addition to the contaminants from the region of the wiring substrate 800, also sealed off from the spark gap housing 112. Thus, neither impurities from the spark gap area nor contamination from destroyed components on the wiring carrier can affect the switching capacity of the fuse 900.
- the other part of the series connection of the safety devices is protected by the housing 700 for the parallel connection from being touched by the wiring substrate and at the same time can not cause arcing on the wiring substrate.
- At least one spark gap of the spark gap arrangement can be triggered and the trigger circuit can be located on the wiring substrate.
- the contacting between the wiring carrier and the spark gap to be triggered can take place via a contact spring which extends through a recess 113 in the housing 112 (FIG. 7).
- spark gap housing 112 has on its upper side a trough-like recess 114, in which the first part 900 of the series compound dips to effect a protective and insulating function (see FIGS. 7 and 8).
- the overall assembly may be surrounded by an insulating cap, the cap having a viewing window to allow a view of the top of the housing 700 and the indicator slide 111, respectively.
- the display slider 111 has a display surface 115.
- This display area can, for. B. have a green color, which signals the state "OK".
- the display slide 111 also has an extension 116 which extends in the longitudinal direction over the narrow side of the wiring substrate 800, to communicate with a telecommunications contact 117 in operative connection.
- the indicator slide 111 has a thorn-like shape, which receives a helical compression spring, which is supported against the spark gap housing 112 in order to generate the necessary pretensioning.
