Schneider Electric Telemecanique LC1D123H7 Contactor

The Schneider Electric Telemecanique LC1D123H7 Contactor is a 3-pole IEC motor-contactor from the TeSys D family designed to reliably switch three‑phase motors and other loads in industrial motor control and power‑switching systems. It features a built‑in 24 V AC control coil (50/60 Hz) and a rated operational current of 12 A (AC-3) with a maximum operating voltage up to 600 V AC, supporting motor power loads up to 5.5 kW at 400/415 V AC (and up to 7.5 HP at 460/480 V AC). The device provides 3 normally open main contacts and a built‑in auxiliary set of 1 NO + 1 NC; it is utilized in AC-3 and AC-4 duties, operates at 50/60 Hz networks, and uses screw clamp terminals. Mounting options include DIN rail or panel mounting, and it offers IP20 protection when installed in an enclosure. Compliance is shown by IEC 60947-4-1, UL Listed, CSA Certified, and CE Marked standards. Operating temperature ranges from -5°C to +60°C, making it suitable for typical industrial environments such as conveyors, pumps, compressors, HVAC equipment, packaging machinery, MCCs, and automated production lines where dependable motor switching and long electrical service life are essential. Common replacements include Schneider Electric LC1D12B7, with alternatives from Siemens (3RT2015) and Allen-Bradley (100-C12D10) also listed.
