Schneider Electric LC1D40ALADN02 AC Contactor

Schneider Electric TeSys D LC1D40ALADN02 is a 3‑pole AC contactor rated for 40 A, designed to switch industrial loads up to 600 VAC with a 120 VAC control coil. The device combines the LC1D40A base contactor with the LADN02 auxiliary contact block, which adds two normally closed contacts for feedback, interlocking, or sequencing in control circuits. The 120 V AC coil is suitable for standard 50/60 Hz control systems, and the 3‑pole configuration provides reliable switching for motors, pumps, and conveyors in commercial and light industrial environments. The LADN02 block mounts on the front of the contactor with screw‑clamp terminals for straightforward wiring, enabling compact panel layouts without additional space for separate auxiliary relays. This combination preserves the robust, industry‑standard TeSys D form factor while expanding control logic options, making it a practical choice for starts/stops, interlocks, or protective interlocks within a single package.
