Siemens 3NA Series Electrical Safety Fuses 3NA3801 LV HRC fuse link

Application:

Siemens LV HRC fuses are used for installation systems in non-residential, commercial and industrial buildings, as well as in the switchboards of power supply companies. They therefore protect essential building parts and installations.

LV HRC fuses are fuse systems designed for operation by skilled personnel. There are no constructional requirements for non-interchangeability of rated current and touch protection.

The components and auxiliary equipment are designed in such a way as to ensure the safe replacement of LV HRC fuses or isolation of systems.

LV HRC fuse links are available in the sizes 000, 00, 0, 1, 2, 3, 4 and 4a.

LV HRC fuse links are available in the following operational classes:

  • gG for cable and line protection
  • aM for the short-circuit protection of switching devices in motor circuits
  • gR or aR for the protection of power semiconductors
  • gS: The new gS operational class combines cable and line protection with semiconductor protection.

LV HRC fuse links are mainly used in LV HRC fuse bases, LV HRC fuse switch disconnectors, LV HRC fuse strips as well as in LV HRC in-line fuse switch disconnectors.

LV HRC signal detectors are used for remote indication that the LV HRC fuse links have been tripped. Three different solutions are available:

  • 3NX1 021 signal detectors with signal detector link 3:
    The LV HRC signal detectors with signal detector link support monitoring of LV HRC fuse links with non-insulated grip lugs of sizes 000 to 4 at 10 A or more. The signal detector link is connected in parallel to the LV HRC fuse link. In the event of a fault, the LV HRC fuse links are released simultaneously with the LV HRC fuse signaling link. A tripping pin switches a floating microswitch
  • 3NX1 024 signal detector top:
    The signal detector top can be used with LV HRC fuse links, sizes 000, 00, 1 and 2, which are equipped with non-insulated grip lugs and have a front indicator or combination alarm. It is simply plugged into the grip lugs
  • 5TT3 170 fuse monitors:
    If a fuse is tripped, the front indicator springs open and switches a floating microswitch. This solution should not be used for safety-relevant plants. For this purpose, we recommend our electronic fuse monitors.

Benefits

  • Clear and visible conductor connection that can be easily checked when using MINIZED switch disconnectors D02. This facilitates cable entry and saves time.
  • Bus-mounting of MINIZED fuse switch disconnectors D01 with three-phase pin busbar, which can be cut to length. Tried and tested.
  • Single-phase busbar mounting of NEOZED fuse bases.
  • Clear and visible conductor connection that can be easily checked when using NEOZED comfort base D02. This facilitates cable entry and saves time.
  • Bus-mounting of NEOZED fuse bases made of molded plastic on three-phase busbar with fork plug, which can be cut to length. Frequently used.
  • Bus-mounting of NEOZED fuse bases made of ceramic on three-phase busbar with fork plug, which can be cut to length. Most common application.
  • Uniform solution for all sizes - signal detectors reliably indicate that the fuse has tripped. Tripped fuses are quickly located. This saves time and increases plant availability.
  • The LV HRC signal detector top is a cost-effective solution for the monitoring of Siemens LV HRC fuse links of sizes 000, 00, 1 and 2.
  • The silver-plated Lyra contact provides a large contact area for the pin of the LV HRC fuse link. This improves heat transmission and lowers the temperature. It also minimizes ageing of the fuse link in the maximum load range, in particular when using SITOR semiconductor fuses.
  • The large contact area also facilitates replacement of LV HRC fuse links.
  • The spring washer tensioning the contact is mechanically galvanized. This will prevent hydrogen embrittlement. The contact is resistant to aging and there will be no dreaded annealing of contacts, which considerably improves operating safety.
