The Schneider Electric LC3D32AQ7 is a TeSys D star delta starter, pre-wired with 3 x 3P (3 NO) power poles, rated 32 A with a 380 V AC coil. It's designed for AC-3 motor control duty — meaning it handles the starting current of squirrel-cage motors during star-delta transition, which is the standard starting method for three-phase induction motors above a few kW. The IP20 front face protection means it's suited for installation inside an enclosure where the front panel is touch-safe but the body needs panel protection from dust and accidental contact.
Sourcing reality — obsolete part
This part is obsolete per the manufacturer. No direct successor is listed. Sourcing is through surplus or broker channels; we can quote against an RFQ. Verify coil voltage (380 V AC) and 32 A rating match your application.
The LC3D32AQ7 carries a fire resistance rating of 850 °C per IEC 60695-2-1 and flame retardance V1 per UL 94. Climatic withstand conforms to IACS and IEC 60947-1 Annex Q category D, and the protective treatment is TH per IEC 60068-2-30 (damp heat, cyclic). The storage temperature range is -60 to 80 °C, and operating temperature is -40 to 70 °C at rated coil voltage.
Mechanical robustness and integration
Mechanical robustness specs: vibrations with contactor open at 2 Gn (5-300 Hz), closed at 4 Gn (5-300 Hz); shocks with contactor closed at 15 Gn for 11 ms, open at 8 Gn for 11 ms. This is a pre-wired unit, so it arrives with the internal star-delta wiring already completed — the installer only needs to connect the incoming supply and motor leads. The IP20 front face means it's intended for panel mounting where the front is accessible but the live parts behind are enclosed.
