Schneider Electric LUCB1XFU TeSys Ultra Advanced Control Unit 0.35-1.4 A 110-240 V AC/DC Motor Starter Module

The Schneider Electric LUCB1XFU is a TeSys Ultra advanced control unit that plugs into an LUB12, LUB320, or LUB380 power base to form a complete TeSys U starter-controller for 3-phase motors up to 0.25 kW at 400 V. It covers an adjustable rated current Ir of 0.35-1.4 A with class 10 overload tripping, and runs on 110-240 V AC / 110-220 V DC control power.

Selection Notes

At 0.35-1.4 A this is the lowest current unit in the LUCB advanced control range, suited to small sub-fractional motors where the standard-function LUCA unit's diagnostics are not enough. It plugs into the LUB12, LUB320, or LUB380 power base interchangeably with other LUCB units carrying a higher Ir range, so the power base does not need to change if the motor is later upsized within the same frame; the thermal alarm can be read locally with a LUFDA module or remotely with a LULC module.

Applications

Fractional-horsepower 3-phase motor starters in machine-building and OEM panels where modular TeSys U construction is already standardized, and where remote diagnostics via LULC communication modules are planned.
