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.
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.
SIRIUS 3RW30 基本性能型软起动器适合三相异步电机的软起动。
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 55 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。

应用
3RW30 软起动器可用于三相异步电机的软起动。
由于两相控制,在整个启动时间内,电流在各个相位始终保持在小值。由于连续电压影响,在星形-三角形起动器条件下无可避免的现象,如电流和转矩峰值,在这种情况下不会发生。
