Schneider Electric Telemecanique LC1-EC03 Contactor

The Schneider Electric Telemecanique LC1-EC03 is an IEC magnetic contactor designed for industrial motor control and power switching, featuring a 3-Pole design with 3 normally open main contacts and a built‑in 1 NO auxiliary contact. It is rated for AC-3 operation at 6 A with a maximum operating voltage of 600 V AC, and it uses a control coil rated for 220–230 V AC at 50 Hz or 220–240 V AC at 60 Hz. The LC1-EC03 is a 3‑pole device from the LC1 series, mounted on panels with screw clamp terminals and suitable for networks at 50/60 Hz, complying with IEC 60947-4-1. This model (LC1-EC03 / LC1EC03) is commonly found in industrial facilities to switch three‑phase motors and electrical loads in equipment such as conveyors, pumps, compressors, fans, HVAC systems, and automated production machinery, making it a core component for repair, replacement, retrofit, or automation maintenance by maintenance teams, OEMs, and system integrators. Common replacements include Schneider Electric LC1K0610M7, Siemens 3RT2015, and Allen-Bradley 100-C09E10 IEC contactors, underscoring its role as a standards‑based, compatible solution within industrial motor control and power switching applications.
