Schneider Electric LC1D18U7 Three Phase Contactor

Schneider Electric LC1D18U7 is a TeSys D three‑pole, nonreversing contactor designed to reliably switch three‑phase motors and other inductive loads. This coil‑driven device uses a 240 V AC coil (50/60 Hz) to energize three normally open contacts, enabling direct interfacing with standard control circuitry. It is rated for 18 A and can switch motors up to 10 HP at 480 VAC, making it a solid choice for general‑purpose motor control in industrial panels. The LC1D18U7 also provides a high short‑circuit current rating up to 100 kA, enhancing protection in fault conditions within typical electrical rooms and panel enclosures. As part of Schneider Electric’s TeSys D family, it offers a compact, modular solution that pairs with protective relays, overloads, and enclosures to assemble dependable motor control circuits.
