Schneider Electric LC1D40AB7 Magnetic AC Contactor

Schneider Electric LC1D40AB7 Magnetic AC Contactor is a 3‑pole TeSys D (Deca) starter designed to switch three‑phase loads from a 24 V AC control circuit. The coil is 24 VAC at 50/60 Hz, and the device is rated for AC‑3/AC‑3e service, delivering 40 A at up to 440 VAC (with a motor rating up to 30 HP at 480 VAC). It uses three normally open contacts (3NO) and is nonreversing, making it a straightforward motor start/stop device for pumps, fans, conveyors, and other automation loads in control panels. The LC1D40AB7 offers a high short‑circuit current rating up to 100 kA SCCR, supporting safe operation in standard industrial electrical systems. Typical installation specs include screw clamp terminals and compatibility with TeSys Deca accessories for panel mounting and interconnection. This contactor is commonly used in three‑phase motor control applications where a compact, reliable switch is needed to energize and de‑energize motors via a 24 V control circuit, often paired with overload relays and auxiliary contacts for signaling and interlock purposes.
