Schneider Electric Telemecanique LC1D3210-LA4DA1U Contactor

The Schneider Electric Telemecanique LC1D3210-LA4DA1U Contactor pairs a 3-pole IEC magnetic contactor from the TeSys D family with an LA4DA1U RC suppressor module, designed for robust control of three-phase motors in industrial motor control and power switching systems. It is commonly installed in motor control centers, conveyors, pumps, compressors, HVAC equipment, and automated production lines. This assembly features 3 NO main contacts and 1 NO built-in auxiliary contact, with a rated operational current (AC-3) of 32 A and a rated thermal current (AC-1) of 50 A; it supports a maximum operational voltage of 600 VAC (690 VAC IEC rated) and Ue up to 690 V AC at 50/60 Hz. The control coil voltage is 110/120 V AC, 60 Hz, and the LA4DA1U suppressor module accepts 110–240 VAC to minimize coil switching transients and EMI, protecting PLC outputs and other control components. Motor power ratings include 10 HP at 230/240 VAC, 20 HP at 460/480 VAC, 30 HP at 575/600 VAC (UL/CSA), and 15 kW at 380/400 V AC (IEC). It uses screw clamp terminals, supports 35 mm DIN rail or panel mounting, and carries an IP20 protection rating with Ui 690 V and Uimp 6 kV; it conforms to IEC 60947-4-1, UL 508, CSA C22.2, and is CE marked. This makes it suitable for repair, replacement, retrofit, or automation maintenance in industrial environments.
