Siemens SIRIUS Soft Starter, 90kW, 162A - 3RW40 Series - 3RW4056-6BB44


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

What diagnostic messaging does this device provide?


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.
