?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.
SILIZED Design
?SILIZED semiconductor fuses have an extremely compact design. This means they have a very small footprint – particularly the NEOZED version
?The rugged and well-known DIAZED design complies with IEC 60269-3. It is globally renowned and can be used in many countries
?A huge range of fuse bases and accessories are available for the NEOZED and DIAZED versions of the SILIZED semiconductor fuses. This increases the application options in many devices.
Cylindrical Fuse Design
?Cylindrical fuses have an extremely compact design and a correspondingly small footprint
?The cylindrical fuses have IEC and UL approval and are suitable for universal use worldwide
?The use of SITOR cylindrical fuses in the cylindrical fuse holders and bases has been tested with regard to heat dissipation and maximum current loading. This makes planning and dimensioning easier and prevents consequential damage
?The use of fuse holders as switch disconnectors expands the area of application of these devices and increases operating safety.
优势
LV HRC Design
?SITOR semiconductor fuses have a high varying load factor, which ensures a high level of operating safety and plant availability – even when subject to constant load change
?The use of SITOR semiconductor fuses in LV HRC bases or Siemens switch disconnectors has been tested with regard to heat dissipation and maximum current loading. This makes planning and dimensioning easier and prevents consequential damage
?Our high standard of quality ensures good compliance with the characteristic curve and accuracy. This ensures long-term protection of devices.
