Siemens SIRIUS 3RA6250-1DB32 Compact Reversing Motor Starter 3-12A 24V AC/DC 5.5kW 690V

Product Description

The Siemens 3RA6250-1DB32 is a SIRIUS 3RA62 compact reversing motor starter designed for switching, reversing, and protecting three-phase motors in industrial control systems. It combines contactor, overload protection, short-circuit protection, and reversing functionality in one compact device. The adjustable current range of 3 to 12 A allows precise matching to the connected motor, while the unit supports motors up to 5.5 kW at 400 V. A 24 V AC/DC control supply, selectable Class 10 or Class 20 overload tripping, integrated signaling contacts, and screw-terminal connections make it suitable for conveyors, pumps, material-handling systems, and automated machinery requiring forward/reverse motor operation.
