Schneider Electric LUCA1XES TeSys U Standard Control Unit 0.35-1.4 A 48 V AC Motor Starter Module

The Schneider Electric LUCA1XES is a TeSys U standard control unit providing adjustable thermal-magnetic motor protection from 0.35 to 1.4 A. Plugged into a LUB12, LUB32, or LUB38 power base, it forms a complete starter-controller with Class 10 overload tripping, phase-failure sensing, and earth-fault detection for 3-phase motors up to 0.25 kW at 400 V, controlled from a 48 V AC / 48-72 V DC supply.

Selection Notes

The LUCA1XES fills the 48 V control-voltage gap between the 24 V LUCA1XB/LUCA1XBL and the 110-240 V LUCA1XFU, covering 48 V AC and 48-72 V DC with one reference. Its 0.35-1.4 A range and Class 10 curve match the rest of the X6/1X family, so the control-voltage choice does not affect motor protection behavior. Choose this version where the plant's control bus runs at 48 V rather than 24 V or mains voltage.
