Schneider Electric LC1D32KUE TeSys Deca Advanced Contactor 3P 3NO AC-3 32 A 100-250 V AC/DC Coil Contactor
TeSys Deca Advanced 3P contactor, 32A AC-3, 15kW at 400V, 100-250 V AC/DC coil.
Description
About the LC1D
About the LC1D
The Schneider Electric LC1D32KUE is a TeSys Deca Advanced 3-pole (3NO) contactor rated 32 A AC-3 at up to 440 V, switching 15 kW motors at 400 V. A sealed low-consumption 100-250 V AC/DC electronic coil covers a wide control-voltage band from a single reference, and 1NO+1NC mirror-certified auxiliary contacts come built in. Screw clamp terminals handle both power and control wiring.

Selection Notes
Because the LC1D32KUE coil is sealed for the full 100-250 V AC/DC band, one part number covers 110 V, 230 V AC and most DC control rails without ordering a separate coil variant. It carries 15 kW motors at 400 V AC-3, and the 550 A breaking capacity at 440 V gives margin for coordination with an upstream circuit breaker. Projects needing a lower current in the same frame can step down to the 18 A LC1D Advanced version with the identical mounting footprint.
