Schneider Electric LC1D09U7 Three-Phase Contactor

Schneider Electric TeSys Deca LC1D09U7 is a 3-pole AC-3 contactor with three normally open main contacts (3NO) rated for 9 A, designed for motor control up to 4 kW at 400 V and up to 440 V line voltage. It is actuated by a 240 V AC coil (50/60 Hz) and offers screw clamp terminals for reliable, easy wiring in control panels; the open-style construction supports straightforward installation in compact enclosures. This nonreversing contactor is part of the TeSys Deca family, ideal for HVAC fans and pumps, conveyors, and other light-to-moderate motor-start applications requiring AC-3/3e duty. The LC1D09U7 series provides a high short-circuit current rating (SCCR) up to 100 kA, enabling robust protection in systems with substantial fault conditions. Commonly selected for installations needing 3NO contacts on a standard 240 VAC control circuit, it pairs with compatible auxiliaries and enclosures to fit typical industrial control schematics. In operation, it delivers dependable switching for motors and inductive loads while maintaining a compact footprint suitable for panel-mounted control circuits and automated equipment integration.
