- Description
The Schneider Electric LC1DT40B7 is a TeSys Deca 4-pole (4NO) contactor rated 40 A AC-1 for non-inductive loads at up to 690 V. It runs on a 24 V 50/60 Hz AC coil common on European machine-tool control circuits, and 1NO+1NC mirror-certified auxiliary contacts are built in for status feedback.

Selection Notes
At the top of the 45 mm resistive-duty frame, the LC1DT40B7 switches 40 A AC-1 across four poles with a 450 A breaking capacity, suited to heater or lighting banks needing full isolation on all legs. The 24 V AC coil matches the low-voltage control-transformer standard on most European panels. The 24 V DC-coil LC1DT40BD sibling carries the identical current rating for DC-control systems.
