Schneider Electric LC1-D253 A65 Contactor

The Schneider Electric Telemecanique LC1-D253 A65 IEC Contactor is a 3-pole TeSys D motor-switching device built for industrial motor control and power switching. It is widely used in motor control centers, conveyors, pumps, compressors, HVAC equipment, packaging machinery, and automated production lines to reliably switch three-phase motors and other electrical loads. Key specifications include a rated operational current (AC-3) of 25 A, a rated thermal current Ith of 40 A, and a continuous current rating of 32 A, with a maximum operating voltage of 600 V AC and a rated insulation voltage Ui of 660 V. The 24 V AC, 50 Hz control coil (A65) drives the 3-pole main contacts, and auxiliary contacts are rated A600 / P600. It uses screw clamp terminals and can be mounted on a DIN rail or panel, weighing approximately 550 g. It is designed for AC-3 and AC-1 utilization categories and adheres to standards including IEC 158-1, UTE 63110, VDE 0660, and BS 5424. Manufactured in France, the LC1-D253 A65 is commonly chosen as a drop-in replacement in repair, retrofit, or automation maintenance projects. For compatibility, Schneider Electric LC1D25B7 and Siemens 3RT2026 IEC contactors are common equivalents, as is Allen-Bradley 100-C23D10.
