Schneider Electric LC1D40AF7 Three-Phase General Purpose Contactor

LC1D40AF7 TeSys D three-pole general-purpose contactor from Schneider Electric is designed for reliable three-phase motor control in industrial automation. It presents three normally open contacts (3 NO) for switching power to a motor, with AC-3 duty rated up to 440 V and a current rating of 40 A per pole. The coil is 110 V AC, 50/60 Hz, enabling straightforward interfacing with common control circuits and relays. In motor-start applications, this model handles motors up to 30 HP at 480 VAC (and 30 HP at 600 VAC, per datasheet), making it suitable for pumps, fans, conveyors, and machine tools. A robust short-circuit current rating of up to 100 kA SCCR supports safe operation in panels with high fault-current levels. As part of the TeSys D family, LC1D40AF7 is typically used with an accompanying overload relay and control electronics to form a complete motor-control circuit. This variant offers straightforward installation and dependable performance in industrial environments where simple, durable motor switching is required, aligning with common control voltages and protection schemes found in HVAC, process, and manufacturing equipment.
