Siemens Soft Starter, 55Kw, 480V AC - 3RW40 Series - 3RW4047-1BB14


This intelligent soft starter from Siemens is an ideal solution for overcoming voltage dips in a 3-phase power-supply system. The unit's 2-phase control keeps current to a minimum in all 3 phases throughout the entire startup time. It also eliminates disturbing direct current components to avoid current and torque peaks from causing damage. The starter motor features overload and intrinsic device protection without the need for extra wiring. Adjustable trip classes and integrated diagnostic functions make for a user-friendly experience. You'll find soft starters like this used to prevent supply voltage fluctuations at start-up in pumping, conveying and compression applications.

• Safe to use in hazardous areas where explosive atmospheres may be present

• Clearly arranged control panel for easy use

• Minimal power loss combined with optimised motor control

• Low heat dissipation to keep control cabinets cool

• Suitable for starting explosion-proof motors with increased safety protection

Can this motor be remotely controlled if it's used in a hazardous location?


Yes it can, as the starter motor includes an integrated remote-reset function that lets you quickly and easily clear faults remotely.
