Schneider Electric LC1D12BD DC Coil Contactor

Schneider Electric's TeSys D LC1D12BD 3-pole DC Coil Contactor (with LADN22 auxiliary block) is an IEC magnetic contactor used in industrial motor control and power switching across MCCs, conveyors, pumps, compressors, HVAC equipment, packaging machinery, and automated production lines. It features a 24 V DC control coil and adds 2 NO + 2 NC auxiliary contacts via LADN22 alongside the built-in 1 NO + 1 NC, enabling interlocking and signaling in PLC-based control schemes. Rated for AC-3 operation up to 12 A and AC-1 up to 25 A, it accepts up to 690 V AC (25-400 Hz) or up to 300 V DC on the power circuit, with rated insulation of 690 V and a 6 kV impulse withstand, and IP20 protection. Motor power ratings scale with supply: 3 kW at 220-230 V, 5.5 kW at 380-440 V, and 7.5 kW at 500-690 V (3 HP at 200/208-230/240 V; 7.5 HP at 460/480 V; 10 HP at 575/600 V); it supports AC-1, AC-3, AC-3e, and AC-4 utilization categories, mounting on 35 mm DIN rail or panel, screw clamp terminals, and is certified to IEC 60947-4-1, UL 508, CSA, and CE.
