  • NH (Low Voltage Heavy Duty) Fuses are used and will be used in conjunction with AC applications mainly used in cable distribution cabinets and low-voltage distributions of energy supply companies for power distribution.
  • Such fuse strips are usually three-pole and intended for mounting on busbars.
  • One contact of each phase is connected to one phase of the three-pole busbar system.
  • the other contacts are provided with connections for conductors.
  • the fuse strips can be designed as a fuse breaker.
  • a fuse strip for NH fuses for AC voltage application wherein the fuse strip is designed as a fuse switch disconnector, is in the EP 1 045 414 A1 described.
  • One housing of the fuse strip has receptacles for six fuse contacts, with two fuse contacts each serving to accommodate an AC fuse-link.
  • the one fuse contact associated with the respective fuse link is connected to a bus bar by means of a first conductor passing through one passage in the housing, and the other fuse contact associated with that fuse link is connected to a terminal for a conductor by means of a second conductor. wherein this connection is designed as a terminal.
  • the first to sixth recording are arranged one behind the other in the longitudinal direction of the housing in this.
  • the two fuse contacts of the first AC fuse-link With the first and second recording, the two fuse contacts of the first AC fuse-link, with the third and fourth recording, the two fuse contacts for the second AC fuse-link and the fifth and sixth recording the two fuse contacts for the third AC fuse-link connected.
  • the first, third and fifth receptacle are associated with the first conductors, which are formed as flat rails and are connected to the three busbars of the busbar system.
  • the second current conductors are designed as flat rails and connect the other fuse contacts of the fuse links with the terminals.
  • the live fuse links are covered with hood-shaped cover elements.
  • the object of the present invention is to provide a fuse strip, which can be formed largely of standardized components, which are provided for an AC application, for a DC application, in particular to provide a special arrangement in this aspect, having these fuse strip.
  • a fuse strip for receiving NH fuse-links wherein a housing of the fuse strip has recordings for six fuse contacts, with four of the six recordings fuse contacts are connected and two fuse contacts serve to accommodate a fuse for DC voltage, the one A fuse contact associated with the respective fuse link is connectable to a bus bar by means of a first current conductor passing through one passage in the housing, and the other fuse contact associated with that fuse link is connected to a terminal for a conductor by means of a second current conductor.
  • the fuse strip for the DC application can be converted for attachment of the fuse strip to two bus bars and electrically conductive connection therewith and electrically conductive connection to the terminals connected to the second conductors are, these connections are designed in particular as terminals.
  • the fuse strip two of the six receptacles remain free, wherein it is provided in particular, that in an arrangement of the first to sixth recording in a row in the longitudinal direction of the housing, with the first and third recording, the two fuse contacts for a fuse link are connected and / or with the fourth and sixth recording, the two fuse contacts for the other fuse link are connected.
  • the two fuse links thus extend across the second and fifth slots.
  • a structurally particularly simple and also particularly cost-effective design of the fuse strip results when the first current conductors and / or the second current conductors are formed as flat rails. It can thus be used conventional flat rails, as used in fuse strips for the AC application.
  • the flat bars, which are connected to the busbars need not be modified in this case with respect to flat bars, which are used in fuse links for the AC voltage application.
  • the other flat bars, which interact with the terminals / terminals, may need to be modified. If the connections / terminals are arranged in the region of the same end of the housing, this applies in particular to the longer flat rail, which in this case can be formed, in particular, by connecting two flat rail sections overlapping each other. Accordingly, it is possible to resort to conventional flat rails, which are severed in the region of different ends of the respective pair of flat rails and can then be overlapped, extended and then connected to one another in these generated end regions.
  • the recorded in the first and sixth recording fuse contacts are connected to the busbar.
  • This arrangement results in a special stability of the connection of fuse strip and busbars, since the busbars are arranged as far apart as possible and the attachment of the fuse strip takes place on the busbars near the ends of the fuse strip. Between the busbars, the other fuse links are connected to the conductors / terminals.
  • the fuse strip is in particular a fuse base or fuse breaker.
  • the object is further achieved by an arrangement of a self-generating system and a fuse strip, wherein the fuse strip is formed according to the above features of the invention and the self-generating system, which is in particular designed as a photovoltaic system, is electrically connected via two busbars with the fuse strip and the fuse strip in the by the busbars formed busbar systems is stored.
