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.
基本性能软起动器 SIRIUS 3RW40 可以用于三相异步电机的软起动和运行停机控制。
由于进行两相控制,不仅可将所有三相的电流在整个起动过程中保持在小值,而且还消除了干扰性的直流成分。这不仅使得电机的两相起动高达 250 kW(400 V 时),也避免了如使用 wye-delta 起动器产生的电流和转矩峰值。
SIRIUS 3RW40 软起动器适合起动保护类型为 ATEX Directive 94/9/EC 的 EEx e 的“增安型”防爆电机。

SIRIUS 3RW40
固态软起动器 SIRIUS 3RW40 可以用于三相异步电机的软起动和运行停机控制。
通过两相控制,整个起动时间内,所有三相中的电流可保持在小值,且避免了干扰直流部件。这不仅使得电机的两相起动高达 250 kW(400 V 时),也避免了如使用 wye-delta 起动器产生的电流和转矩峰值。

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.
