Reversing contactor, 9 A at 24 VDC coil
The 3RA9012-5AL12: The integral SU (suppressor unit) is built in — no separate snubber needed across the coil for DC switching transients. Reversing contactors pair two mechanically interlocked contactors so both cannot close simultaneously — critical for direction-change circuits on conveyors, hoists, or pump drives where a cross-closure would short the phases.
