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
•SITOR 熔断器具有各种负载系数，可确保高度的操作安全和工厂可用性。
•SITOR 熔断器的散热和电流负载在 Siemens LV HRC 熔断器座或隔离开关中已进行测试。这使规划和尺寸设计更加*，避免了间接损坏。
•较高的质量标准可确保良好的特性曲线和精度一致性。从而可保证设备长期保护。
操作等级
根据功能和操作等级以熔断器进行分类。在LV HRC设计中的SITOR半导体熔断器适用于下列操作等级：
•aR:用于功率半导体器件的短路保护
（部分范围保护）
•gR:用于功率半导体器件的保护
（完全范围保护）
•gS:gS操作等级将电缆和线路保护与半导体器件保护相结合（全范围保护）。
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).

•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 - ** detectors reliably indicate that the fuse has tripped. Tripped fuses are quickly located. This saves time and increases plant availability.
•The LV HRC ** 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.

概述
SITOR 熔断器比常规低压 HRC 熔断器分断更快，可保护功率半导体免受短路影响。从而可保护昂贵的设备和系统部件，例如输入、直流链路、UPS 系统或电机软起动器中的带熔断器变频器。
面板安装要求各种连接型式。
刀形触头熔断器符合 IEC 60269-2 标准，适用于安装在 LV HRC 熔断器座和 LV HRC 熔断器式隔离开关中。这也适用于开槽触头型熔断器，用于螺钉固定，安装尺寸 110 mm，尺寸符合标准 IEC 60269-4。
螺钉固定、安装尺寸 80mm 或 110 mm开槽触头型熔断器常用螺钉直接安装在母排上，便于散热。带 M10 或 M12 母螺纹的小型熔断器散热效果更好，可直接安装在母排上。
安装尺寸 80 mm 的螺栓型熔断体是另一种面板安装型，也可直接安装在母排上。
用于 SITOR 晶闸管组、铁路整流器或电解系统的熔断器专为这些应用开发。
用于 SITOR 熔断器 的 LV HRC 熔断器座和安全切换装置，可查阅“低压熔断器系统”章节。
在 “ET B1 附加特性曲线”样本中和互联网上能够找到 SITOR 熔断器针对 3NP 和 3KL 熔断器底座以及 3NP 和 3KL 安全转换装置的配置和分配特性曲线。
尺寸为3的新型的产品系列为圆形而不是正方形的陶瓷体。这些系列产品的特性是：I²t 值小，功率耗散低，在交变负载情况下性能高。在外形尺寸和功能外形尺寸上均符合与当前的IEC 60269-4/ DIN EN 60269-4 (VDE 0636-4)标准。
