Schneider Electric LC1D12 Three Phase Contactor

The Schneider Electric TeSys D LC1D12 IEC magnetic contactor is a 3-pole, 12 A AC-3 rated motor controller designed for three-phase loads in industrial motor control and power switching systems such as conveyors, pumps, compressors, HVAC equipment, packaging machinery, and automated production lines. It operates from a 120 V AC control coil (50/60 Hz) and switches up to 600 V AC (690 V IEC rated), with motor power handling of 3 HP at 200/208–230/240 VAC, 7.5 HP at 460/480 VAC, and 10 HP at 575/600 VAC. Built-in auxiliary contacts provide 1 NO + 1 NC, and the device supports utilization categories AC-1, AC-3, AC-3e, and AC-4. The LC1D12 uses screw clamp terminals and can be mounted on a DIN rail or panel, with a rated insulation voltage of 690 V AC and a rated impulse withstand voltage of 6 kV. It carries IP20 enclosure protection and complies with IEC 60947-4-1, UL 508, CSA C22.2 No. 14, and is CE marked. Common replacements include the Schneider Electric LC1D12G7 Contactor for similar duty, and the part is commonly used by maintenance teams, OEMs, and system integrators for repair, replacement, retrofit, or industrial automation tasks.
