Schneider Electric LC1F185 Three Phase Contactor

The Schneider Electric LC1F185 TeSys F three‑phase contactor with LR9F5369 electronic thermal overload relay is a heavy‑duty magnetic starter designed for reliable switching and precise overload protection in industrial motor control systems. This 3‑pole device (3 NO) delivers a rated operational current (AC‑3) of 185 A, a conventional thermal current Ith of 200 A, and supports a rated operational voltage (Ue) up to 600 VAC (IEC rating to 1000 VAC) with an insulation voltage (Ui) of 1000 VAC. The LR9F5369 overload relay provides electronic thermal protection with phase‑loss sensitivity and manual reset, adjustable from 90 to 150 A, and a Class 10 thermal overload rating. An auxiliary contact set offers 1 NO + 1 NC for control interlock and feedback signals. Compatible devices include LC1F115, LC1F150, and LC1F185 TeSys F contactors, and mounting can be direct on the contactor or plate mounted. The assembly adheres to IEC 60947‑4‑1, UL, and CSA standards and is commonly employed in MCCs, conveyors, pumps, compressors, packaging machines, HVAC systems, and other industrial control panels where dependable motor starting and protection are essential.
