Schneider Electric LC1D80U7 Three-Phase AC Contactor

Schneider Electric TeSys D LC1D80U7 is a 3-pole, non-reversing AC-3 contactor rated for 80 A to control three‑phase motors and other AC‑3 loads. It provides three normally open main contacts plus an integrated auxiliary contact (1 NO + 1 NC) for signaling or interlocking, and it uses a 240 V AC control coil compatible with 50/60 Hz networks. The power circuit can be operated up to 440 V AC (with a rated operational voltage to 690 V AC for AC‑3 use), and the unit carries a short‑circuit current rating up to 100 kA SCCR for high‑inrush motor starts. In terms of motor power, it suits about 22 kW (roughly 60 HP) at 230/240 V AC, 37 kW at 380–400 V, 45 kW at 415–440 V, and remains suitable for higher‑voltage drives at 460–480 V, depending on supply voltage. Dimensions place LC1D80U7 at about 85 mm wide, 127 mm high, and 130 mm deep, with screw‑clamp terminals for secure wiring. This LC1D80U7 variant is part of Schneider Electric’s TeSys D family, designed for reliable, high‑duty motor control in industrial automation and panel installations.
