軟啟動 Sirius 3RW40 適用于三相異步電動機的軟啟動和降級標準應用。集成旁路允許非常緊湊的結構、并確保控制柜中的低散熱性。智能監控功能可防止軟啟動器過熱、防止電動機過載。此外，您還可以將啟動期間的電流限制為可設置的最大值。
通過集成遠程重置、您可以從遠程位置快速、輕松地清除故障。全球審批（例如 iec 和 ul/csa ）、也適用于危險區域（ atex 或 iec ex ）中的應用。
3RW 軟啟動器可用于各種性能范圍內高達 690 v 的電源系統、具有不同的控制電源電壓、并具有螺釘和彈簧型接線端子。對于 245/40 、還有其他型號的控制電源電壓為 3RW30 。部分 3RW40 直至尺寸 S3 、所有 3RW44 裝置還提供熱敏電阻電動機保護。
通過可選鏈路模塊、軟啟動器可連接到斷路器、即使是帶彈簧型接線端子的型號。可選風扇允許在控制柜中采用更緊湊的設計。簡單、高效且始終保持最新 Sirius 模塊化系統。

This Siemens SIRIUS soft starter features a 2-phase control that's ideal for starting up and winding down 3-phase asynchronous motors. It preserves minimum current values through startup, avoiding sudden surges and peaks to deliver steadier and more efficient operation. Integrated diagnostic functions and adjustable trip classes protect against motor overload, so you can be confident that this starter will function safely and effectively. Its compact design (with 120mm width) and simple screw mounting let you fit it into small spaces. Thanks to a rotatable design, you can choose the placement that suits you on a vertical surface.
? Control voltage of 230V AC (alternating current) and current rating of 162A for heavy-duty use
? Intrinsic device protection ensures smoother operation
? Option to set a maximum value during start-up if you need to limit the current
? Ideal for conveyor systems, with condition and fault monitoring that ensures systems run as smoothly as possible
This starter uses LED (light-emitting diode) technology to convey messages about power failure, phase failure and thermal overload, as well as loss of load and inadmissible tripping times. This high level of fault messaging enhances safety and efficiency.
