Schneider Electric LC1D50U7 Three-Phase Contactor

Schneider Electric's TeSys D LC1D50U7 is a 3-pole, 50 A AC-3 motor-contactor designed for safe, reliable control of inductive loads in electrical panels. It features three normally open contacts (3NO) in a non-reversing configuration and is rated for line voltages up to 440 V AC, with a short-circuit current rating (SCCR) up to 100 kA for demanding start‑ups. The coil is energized from 240 V AC at 50/60 Hz, enabling straightforward integration with standard control circuits, while the unit’s 50 A rating suits light-to-medium motor control applications. This LC1D50U7 model sits in Schneider Electric’s TeSys D family and offers robust wiring via screw-clamp terminals and compatibility with common protective accessories and interlocks in motor starter assemblies. Typical uses include conveyors, fans, pumps, and other automation loads where reliable AC-3 duty and quick switching are required, and its compact 3-pole design helps simplify panel layouts in industrial environments. Ideal for control panels, machine builders, and retrofit projects seeking a proven, durable starter solution for motors up to 50 A, with easy field wiring and broad compatibility across Schneider Electric’s protective-device options.
