Schneider Electric LC1D18 LADN22 Contactor Relay

Schneider Electric's LC1D18 LADN22 Contactor Relay is a TeSys D three-pole motor-contactor assembly rated for 18 A on AC-3 duty in three-phase circuits up to 600 V, with a 120 V AC coil. In this package, an auxiliary contact block (LADN22) mounts on the contactor—top-mount with screw-clamp terminals—and provides two normally open and two normally closed contacts to fan out control signals, interlocks, or feedback without requiring a separate relay. The LADN22 block is compatible with LC1D09 through LC1D150 contactors in the TeSys D family, enabling compact, integrated expansion of auxiliary circuits for motor control, automation sequencing, and equipment interlocks in a single, robust enclosure. This combination is designed for reliability in industrial environments, offering the familiar Schneider Electric TeSys D ecosystem, standard 600 V maximum line voltage, and a 120 V coil variant, making it suitable for installations that rely on medium-power three-phase control.
