The coil is 400 V AC, so it pulls in directly from a standard 400 V three-phase control supply without a separate transformer.
This is a pre-wired assembly, so it lands in the enclosure as a single unit — no on-site wiring between the main and delta contactors. The TeSys D range snaps onto DIN rail or mounts with screws, and the 3 x 3P pole arrangement gives you three NO contacts per phase for the star, delta, and line contactors.
Mechanical robustness for conveyor and material handling lines
Vibration resistance is 2 Gn (5-300 Hz) with the contactor open and 4 Gn (5-300 Hz) closed. Shock resistance is 6 Gn for 11 ms open, 15 Gn for 11 ms closed. That's enough to keep the starter from dropping out on a conveyor line with moderate vibration from motor-roller drives or divert mechanisms.
