紧凑型 SIRIUS 3RW30 软起动器所需的空间仅为用于比较额定值 wye-delta 起动的接触器所需空间的三分之一。这不仅节约了控制柜和标准安装导轨的空间，还*省去了 wye-delta 起动器所需的布线工作。这对于高电机额定值尤为明显，这些高额定值极少用作高技术解决方案。

同时，连接起动器和电机所需的电缆从六根减少到三根。紧凑的外形尺寸、短起动时间、简单布线和快速调试使得软起动器具有明显的成本优势。

这些软起动器的旁通触点在工作时由一个集成固态灭弧系统保护。从而在故障时可防止对旁通触点的破坏，如线圈操作机构或主操作弹簧的短暂的控制电压故障、机械震动或与寿命相关的部件缺陷。

新设备系列采用“极性平衡”控制方法，用于保护两相控制的软起动器中的直流部件。对于两相控制软起动器，来自两个控制相位重叠的电流会流经未受控制的相位。这也是导致电机软起动中三相电流非对称分布的物理原因。这虽然不受影响，但在大多数应用中仍不可忽视。

控制功率半导体不仅导致不对称，在起动电压低于电机起动电压值的 50 % 时，还导致之前提到的直流部件产生严重的噪音。用于这些软起动器的控制方法省去了软起动相位的直流部件，并防止了可能产生的制动扭矩。

该方法创建了在速度、扭矩和电流上升上*的电机软起动，从而可实现电机的缓和两相起动。同时，起动操作的声音质量与三相控制软起动器接近。可通过电机软起动期间不同极性半波电流的持续的动态协调和均衡来实现。因此命名为“极性平衡”。

• 电压斜坡软起动；起动电压的调节范围 Us 为 40% 至 *，斜坡时间 tR 为 0s ~ 20s。
