Schneider Electric LC1D09 Contactor

The Schneider Electric LC1D09 Contactor (TeSys D) is a three-pole IEC magnetic contactor used to switch three-phase motors and electrical loads in industrial motor control and power switching systems such as MCCs, conveyors, pumps, compressors, HVAC equipment, packaging machinery, and automated production lines. It is rated for 9 A AC-3 (motor load duty) and 25 A AC-1, with a maximum operational voltage of up to 690 V AC, and features built-in auxiliary contacts (1 NO + 1 NC) for signaling and interlocking. The device uses screw clamp terminals and can be mounted on a DIN rail or panel, with a mechanical durability of up to 15 million operating cycles and an IP20 front face. It supports utilization categories AC-1, AC-3, and AC-3e and offers a power‑circuit frequency range of 25–400 Hz, meeting IEC 60947-4-1 along with UL Listed, CSA Certified, and CE Marking standards. Common replacements include Schneider Electric LC1D09, Siemens 3RT2015 IEC Contactor, and Allen-Bradley 100-C09 IEC Contactor.
