Schneider Electric LC1D50M7 Three Phase Contactor

LC1D50M7 is a TeSys D three‑pole contactor designed for motor control in AC circuits. It provides 3 Form A (three normally open) contacts and is rated for 50 A on AC‑3 duty, enabling reliable switching of 3‑phase motors in light to moderate load applications. The device accepts line voltages up to 440 V AC for AC‑3/AC‑3e operation, and can drive motors up to 40 HP at 480 VAC. The coil is 220 V AC at 50/60 Hz, allowing direct energization from standard control circuits, and it carries a short‑circuit current rating up to 100 kA SCCR for protection against fault conditions. Wiring is typically through screw clamp terminals, and the LC1D50M7 is part of Schneider Electric’s TeSys Deca family for use in industrial control cabinets and machines such as conveyors, pumps, fans, and machine tools. This model’s combination of 50 A switching capacity, three‑pole, 3 NO contact arrangement, and compatible coil voltage makes it a compact, robust choice for controlling medium‑sized three‑phase loads in commercial and light industrial automation systems.
