Schneider Electric LUCA05ES TeSys U Standard Control Unit 1.25-5 A 48 V AC/DC Motor Starter Module

The Schneider Electric LUCA05ES is a TeSys U standard control unit with an adjustable motor current range of 1.25-5 A, inserted into a compatible power base to form a starter controller for 3-phase motors up to 1.5 kW at 400-440 V AC. It provides Class 10 thermal overload protection, phase-failure sensing, and a 48 V AC/DC control coil.

Selection Notes

Set Ir within the 1.25-5 A window to match the motor's full-load current; Class 10 tripping at 14.2 x Ir covers standard-duty starts without needing a slower overload class. This standard control unit covers basic overload, short-circuit, phase-failure and earth-fault protection without a remote diagnostic output - pick it over the advanced control unit in this current range when the panel doesn't need a thermal-alarm signal or local test push button.
