Schneider Electric LC1D40M7 Motor Starter Assembly

The Schneider Electric LC1D40M7 Motor Starter Assembly is a modular motor control unit that pairs a 40 A electromagnetic contactor with a 120 V coil and a thermal overload relay adjustable from 30 to 40 A, designed for three-phase AC motors in industrial automation. It provides motor switching and thermal overload protection in a single assembly, simplifying installation in control cabinets and in equipment such as conveyors, pumps, compressors, HVAC systems, and packaging machinery. Mounting options include DIN rail or panel mount depending on configuration. The assembly supports IEC motor control and protection systems and is commonly used in factory automation where reliable motor starting and overload protection are essential. Key specifications include a 40 A contactor, 120 VAC coil, overload range of 30–40 A, and 120 VAC control voltage. Common replacements listed are Schneider Electric TeSys D LC1D40 + LRD36 Motor Starter, TeSys F Motor Starter Assembly, and ABB AF40 Contactor with TA42DU Overload Relay.
