Schneider Electric LC1D09BD Three Phase Contactor

The Schneider Electric LC1D09BD TeSys D three-pole non-reversing magnetic contactor handles up to 9 A (AC-3) at voltages up to 690 VAC, enabling reliable switching of three-phase motors in industrial control panels and motor control centers. With 3 poles (3 normally open) and a built-in auxiliary contact (1 NO + 1 NC), it provides straightforward control and signaling for automation sequences. Its coil operates at 24 VDC (BD coil code), and the unit delivers motor power ratings of 2.2 kW at 220–230 VAC, 4 kW at 380–440 VAC, and 5.5 kW at 500–690 VAC (AC-3), making it suitable for a range of load classes in industrial facilities. Utilization categories include AC-1, AC-3, AC-3e, and AC-4, while a rated impulse withstand voltage of 6 kV supports rugged operation in harsh environments. Wiring is via screw clamp terminals, and mounting supports DIN rail or panel installation to suit control-panel layouts. Compliance covers IEC 60947-4-1, UL, and CSA, aligning the LC1D09BD with common industrial motor-control standards. Common applications span conveyors, pumps, compressors, packaging machines, HVAC systems, and general automation panels where dependable electrical interlocking and machine control are essential. Common replacements include Siemens SIRIUS 3RT2015 and Allen-Bradley 100-C09, with the Schneider Electric LC1D09BD TeSys D Non-Reversing Contactor serving as the baseline model.
