Schneider Electric LC1D258G7 Three Phase Contactor

The Schneider Electric LC1D258G7 TeSys Deca is a four-pole, 40 A AC-1 rated contactor with a 120 V AC coil, designed for nonreversing operation in three-phase motor circuits. This open-style device provides two normally open and two normally closed auxiliary contacts (2NO/2NC) to support interlocking and control logic, and it is rated for power circuits up to 440 V AC-1 with a current rating of 40 A at ambient temperatures up to 60 °C. The 120 V AC coil operates at 50/60 Hz, enabling reliable energization from common control circuits, while the main contacts are sized for three-phase switching tasks. Terminals use screw-clamp connections for secure wiring, and the LC1D258G7 is part of Schneider Electric’s TeSys D family, a line of robust industrial contactors designed for demanding loads. Typical applications include starting and stopping three-phase motors, pumps, fans, and conveyors in automation and manufacturing environments, where compact form factor and straightforward wiring help reduce panel complexity.
