It carries three power poles, each 3 NO, rated for AC-3 motor-switching duty at 9 A. The 240 V AC coil is built into the assembly, so the wiring path is simpler than building a star-delta from separate contactors and a timer — one order code, one DIN-rail footprint, fewer terminal points to check. The 9 A rating is in AC-3 utilisation category, which is the standard for squirrel-cage motor switching — making and breaking stalled-rotor currents. That 9 A is the motor full-load current it can handle, not a resistive-heater current. For a 400 V three-phase motor, 9 A roughly corresponds to a 4 kW load. Storage temperature range of -60 to 80 °C and operation from -40 to 70 °C at rated coil voltage cover outdoor or unheated enclosures. This is a panel-mount component — clips onto standard DIN rail. The pre-wired design reduces field wiring time, but the incoming motor leads and control-circuit connections still need to land on the screw terminals. IP2X on the front face means finger-safe from the front; the rest of the enclosure provides the overall IP rating. Vibration resistance: 2 Gn when open, 4 Gn when closed, over 5–300 Hz. Shock: 10 Gn open, 15 Gn closed, 11 ms half-sine. That puts it in the range for general industrial machinery — conveyors, pumps, compressors — but not for high-shock applications like forging presses without additional isolation.","metaTitle":"Schneider LC3D090AU7 TeSys D Star-Delta Starter, 9 A, 240 V","metaDescription":"Active TeSys D star-delta starter, 3 x 3P (3 NO), 9 A AC-3, 240 V AC coil.

The same 9 A, 3 x 3P mechanical assembly is used across multiple coil voltages; the only difference is the coil rating.
