Schneider Electric LC1D18B7C Three Phase Contactor

Schneider Electric LC1D18B7C TeSys Deca is a three-pole, 3 normally open (3 NO) contactor with a 24 V AC coil, designed for AC-3/AC-3e duty up to 440 V and a load current rating of 18 A on the power circuit. It uses screw-clamp terminals for secure wiring and is part of the TeSys D (Deca) family, optimized for compact installation in control panels and motor-control cabinets. This device is intended for starting and switching three-phase loads such as motors, fans, pumps, and conveyors in industrial automation, where reliable actuation and straightforward control integration are important. The 24 V AC coil operates at 50/60 Hz, enabling easy interfacing with standard automation outputs and PLCs, while the 3-pole configuration provides independent switch paths for each phase, minimizing cross-talk and ensuring balanced switching on typical IEC 60947-4-1 style circuits. Maximum line voltage rating up to 440 V across the load ensures compatibility with common industrial power systems, making LC1D18B7C a common choice for small-to-mid-size motor control applications in manufacturing, processing, and packaging environments.
