2 Product overview Overview Devices Page Field of application Standards Used in /3 Fuse links in LV HRC design and a huge variety of models support a wide range of applications from 500 V to 1500 V and 150 A to 1250 A. Fuses with slotted blade contacts, bolt-on links or female thread and special designs. Non-residential buildings Residential buildings Industry SITOR, cylindrical fuse design /17 Fuse links, fuse holders can be used as fuse switch disconnectors and fuse bases to 00/90 V AC and 00/700 V DC from 1 to 0 A in sizes 38 mm, 1 51 mm and mm SILIZED, NEOZED and DIAZED design /22 NEOZED fuse links for 00 V AC and 250 V DC and DIAZED for 500 V AC and 500 V DC /2 Siemens ET B1 /2008

3 BETA Protecting Overview SITOR fuses protect power semiconductors from the effects of a short circuit because the super-quick disconnect characteristic is far quicker than that of conventional LV HRC fuses. They protect expensive devices and system components such as converters with fuses in the input and in the DC link, UPS systems and soft starters for motors. Panel mounting requirements have given rise to various connection versions and designs. The fuses with blade contacts comply with IEC and are suitable for installation in LV HRC fuse bases, in LV HRC switch disconnectors and in switch disconnectors with fuses. They also include fuses with slotted blade contacts for screw fixing with 1 mm mounting dimension, whose sizes comply with IEC Fuses with slotted blade contacts for screw fixing with 80 mm or 1 mm mounting dimension are often screwed directly onto busbars for optimum heat dissipation. Even better heat transmission is provided by the compact fuses with M or M12 female thread, which are also mounted directly onto busbars. Bolt-on links with 80 mm mounting dimension are another panel-mounting version for direct busbar mounting. The fuses for SITOR thyristor sets, railway rectifiers or electrolysis systems were developed specially for these applications. To find out which LV HRC fuse bases and safety switching devices can be used with the SITOR fuses, please refer to the chapter "Low-voltage fuse systems". The characteristic curves for the configuration and assignment of SITOR fuses to fuse bases and 3NP and 3KL safety switching devices can be found in the Catalog ET B1 Add-On Characteristic Curves and on the Internet. The new size 3 type ranges have a round ceramic body instead of a square one. Key features of these type ranges are small I²t values with low power dissipation and a high alternating load capability. The dimensions and the functional dimensions comply with the current standards IEC 029-/EN 029- (VDE 03-). Note: The ordering data of the fuses are listed in ascending order of the rated voltage in the selection tables. Benefits SITOR 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 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. Operational classes Fuses are categorized according to function and operational classes. SITOR semiconductor fuses, in LV HRC design, are available in the following operational classes: ar: for the short-circuit protection of power semiconductors (partial range protection) gr: for the protection of power semiconductors (full range protection) gs: The gs operational class combines cable and line protection with semiconductor protection (full range protection).

17 BETA Protecting SITOR, cylindrical fuse design Overview SITOR cylindrical fuses protect power semiconductors against the effects of short circuits because the super quick disconnect characteristic is far quicker than that of conventional fuses. They protect expensive devices and system components such as semiconductor contactors, electronic relays (solid state), converters with fuses in the input and in the DC link, UPS systems and soft starters for motors up to 0 A. The cylindrical design is approved for industrial applications. The cylindrical fuse links comply with IEC 029. Cylindrical fuse holders also comply with IEC 029 and UL 512. The cylindrical fuse holders for x 38 mm and 1 x 51 mm have been tested and approved as fuse switch disconnectors and the cylindrical fuse holders for 22 x 58 mm as fuse disconnectors according to the switching device standard IEC The utilization category and the tested current and voltage values are specified in the Table "Technical Specifications". The cylindrical fuse holders have been specially developed for the application of SITOR fuse links with regard to heat tolerance and heat dissipation and are therefore not recommended for standard applications. Cylindrical fuse bases do not offer the same comprehensive touch protection as the fuse holders, but have better heat dissipation. The single-pole cylindrical fuse bases for 1 x 51 mm and 22 x 58 mm allow modular expansion to multipole bases. Benefits 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.

22 SILIZED, NEOZED and DIAZED design Overview SILIZED is the brand name of the NEOZED fuses (D0 fuses) and the DIAZED fuses (D fuses) with super quick characteristic for semiconductor protection. The fuses are used together with fuse bases, fuse screw caps and accessories of the standard fuse system. SILIZED fuses protect power semiconductors from the effects of short circuits because the super quick disconnect characteristic is far quicker than that of conventional fuses. They protect expensive devices and system components such as semiconductor contactors, static relays, converters with fuses in the input and in the DC link, UPS systems and soft starters for motors up to 0 A. If using fuse bases and fuse screw caps made of molded plastic, always take into account the maximum permissible values of power loss due to the high power dissipation (power loss) of the SILIZED fuses. If using these components, the following maximum permissible power losses apply: NEOZED D02: 5.5 W DIAZED DII:.5 W DIAZED DIII: 7.0 W. For this reason, in some cases, a thermal permanent load of only 50 % is possible. The DIAZED screw adapter DII for 25 A is used for the 30 A fuse link. Benefits SILIZED 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 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 fuses. This increases the application options in many devices.
