The 3RA6250-2EB33 is a SIRIUS compact reversing starter — a single device that handles forward/reverse motor control without external contactor interlocking. The 15 kW rating at 400 V sets the motor size it can switch in AC-3 duty; the 53 kA breaking capacity at 400 V means it safely interrupts fault currents up to that level without cascading upstream protection. The adjustable trip class (Class 10 or 20,) lets you match the overload curve to the motor start profile — Class 10 for short acceleration times like pumps, Class 20 for high-inertia loads like fans or conveyors. The 24 V AC/DC control voltage is standard across modern PLC outputs; the 3.5 W AC / 3.1 W DC coil draw keeps the control transformer or power supply budget modest. The screw and snap-on mounting onto standard DIN rail means panel integration is straightforward — no special brackets needed.
Deployment context
The plug-in main circuit terminals simplify replacement: the wiring base stays in the panel, the device swaps out without re-terminating power cables. Rated for continuous operation per IEC 60947-6-2, so it handles sustained motor runs without derating.
