- Description
The Schneider Electric LC1DT40F7 is a 4-pole TeSys Deca contactor rated 40 A AC-1 at up to 440 V AC, built for resistive-load switching rather than motor starting. It runs on a 110 V AC 50/60 Hz coil and ships with 1 NO + 1 NC mirror-certified auxiliary contacts built in, screw clamp terminals, and a 45 mm DIN-rail or plate-mount body.

Selection Notes
The 4P/4NO contact arrangement and AC-1 rating target resistive loads — heater banks, lighting circuits — not three-phase motor AC-3 switching; pick a higher-current variant in the same range for loads above 40 A. The built-in 1 NC mirror contact lets an interlock circuit confirm all four poles are open before enabling a parallel circuit. The 110 V AC 50/60 Hz coil needs a control supply at that exact voltage, so check the panel's control transformer tap before specifying this coil code.
