Schneider Electric LC1D09W7 AC Electromechanical Contactor

LC1D09W7 TeSys D contactor by Schneider Electric is a three‑pole AC‑3 motor‑contactor designed to switch three‑phase loads up to 9 A, making it suitable for small to mid‑size motors and similar control circuits. The coil is rated for 277 VAC at 50/60 Hz, while the main circuit accepts up to 440 VAC in AC‑3 service, enabling reliable switching of typical industrial motors. It features three normally open main contacts and includes a built‑in auxiliary contact configuration of 1 normally open and 1 normally closed (1 NO/1 NC) for signaling or interlock purposes, with wiring accomplished via screw‑clamp terminals for straightforward panel wiring. In horsepower terms, the LC1D09W7 covers about 7.5 HP at 575/600 VAC (50/60 Hz) or roughly 4 kW at 400 VAC, making it a common choice for motor control applications across automation, HVAC, pumps, and conveyors. This TeSys D device is part of Schneider Electric’s long‑standing line of compact, reliable contactors designed for durable mechanical and electrical performance in demanding environments, where compactness and easy integration with control circuits are valued.
