Schneider Electric LC1D50AF7 Three-Phase AC Contactor

Schneider Electric LC1D50AF7 TeSys D is a three‑pole AC contactor rated 50 A for AC‑3 duty, designed to start and switch three‑phase motors and other heavy loads in control panels. It provides three normally open contacts (3 NO) in a non‑reversing configuration and uses a 110 V AC control coil rated for 50/60 Hz. The device switches line voltages up to 440 V AC‑3 (regional variants list 400 V), with typical motor‑circuit ratings of about 22 kW at 400 V AC‑3 and roughly 40 HP at 480 V, depending on the supply. As part of Schneider Electric's TeSys D family, LC1D50AF7 is RoHS compliant and offers robust coil response with a short‑circuit current rating up to 100 kA SCCR in suitable configurations. This makes it a solid choice for motor control, conveyors, pumps, and other three‑phase load switching in industrial automation.
