What this motor starter delivers
The 3RA9012-5AF06: The surge suppressor is built into the contactor coil circuit, protecting the control wiring from voltage transients during switching — a common failure point in unsuppressed starters driving inductive loads like conveyors or pumps.
Panel integration notes
The 3RA9012-5AF06 mounts on a standard DIN rail and occupies one modular width. The integral surge suppressor is wired across the coil — verify the control voltage matches the coil rating before applying power.
