Schneider Electric LC1D12BD Contactor is a 3-pole IEC magnetic contactor from the TeSys D family, designed for three-phase motor control and power switching in industrial motor control and power switching systems. It uses a 24 V DC control coil (BD coil code) and provides built-in auxiliary contacts (1 NO + 1 NC) for PLC-driven automation and interlock needs. The device is rated AC-3 12 A and AC-1 25 A, with a maximum operational voltage of 600 VAC (690 VAC IEC rated) and rated insulation voltage of 690 V AC; the power circuit supports up to 300 V DC. It offers screw clamp terminals and can be mounted on 35 mm DIN rail or panel. Motor power ratings are 3 kW at 230 V, 5.5 kW at 380–440 V, and 7.5 kW at 500–690 V, with UL/CSA horsepower ratings of 3 HP, 7.5 HP, and 10 HP respectively. The unit meets AC-1, AC-3, AC-3e, and AC-4 utilization categories and standards IEC 60947-4-1, UL Listed, CSA Certified, and CE Marked, with IP20 protection and 6 kV impulse withstand. Common replacements include Siemens 3RT2016 SIRIUS Contactor and Allen-Bradley 100-C12D10 IEC Contactor.
