3RW44系列软起动器是对现有西门子软起动器性能进一步提升后的产品，可用于苛刻起动工艺条件下的软起动和软停车。藉由高的功能以及简便的操作员控制和集成在复杂结构中的丰富诊断功能等诸多优点，3RW44软起动器已成为变频器起停电机的佳代替品。3RW44结构紧凑，秉承了SIRIUS软起动器的优点，可以用于控制柜需要节省空间、清晰排布的场合。与变频器相比，SIRIUS 3RW44软起动器具有较高的节能潜力。全新闭环转矩控制和可选限流功能使其应用较为广泛。它能可靠防止电机起停时的转矩冲击和电流尖峰，节省配电柜设计成本及机器维修和维护费用。该产品操作简便，用户界面友好。SIRIUS 3RW44还具有其他集成保护功能，例如，其中集成的旁通接触器可以降低软起动器运行过程中的功率损失；具有内部设备过载保护功能，可防止功率模板中的晶闸管热过载；可以选用SITOR半导体保护熔断器来防止晶闸管短路。SIRIUS 3RW44可以利用PROFIBUS DP模块的通讯能力及其控制输入和可编程继电器输出很容易地快速集成到上位控制系统中。另外，SIRIUS 3RW44爬行功能可用于定位和调试任务，使电动机可以以较小的转矩和可调的低速双向转动。如果需要快速停车，SIRIUS 3RW44也具有内置的直流制动功能，可以快速停止驱动负载。
