- Description
Rated 50 A AC-3 at up to 440 V, the Schneider Electric LC1D50AV7 is a TeSys Deca 3-pole (3NO) contactor built for 22 kW motors at 400 V. Its 400 V 50/60 Hz AC coil connects directly to a three-phase supply, and EverLink BTR screw connectors on the power circuit keep torque without the periodic retightening screw terminals need.

Selection Notes
Wiring the coil directly to a 400 V three-phase feeder, the LC1D50AV7 skips the control transformer a lower-voltage coil variant would need, which simplifies the bill of materials on panels already running 400 V. It shares the 900 A breaking capacity and 22 kW at 400 V AC-3 rating with the 48 V AE7 sibling, differing only in coil voltage. Confirm the upstream control fuse is rated for the 160 VA inrush before connecting multiple coils to one circuit.
