What This Contactor Is
The ABB 1SFL551001R8822 is a current-production electrical contactor from the Contactors and Starters line, built for switching and controlling power circuits in industrial automation, motor control, and distribution panels. It weighs 2.45 kg, which aligns with a higher-current frame size — expect a robust magnetic coil and main contact assembly rated for heavy-duty cycling. This is a standard-duty contactor, not a reversing or reduced-voltage starter; it closes and opens a single load circuit under coil control.
