Schneider Electric LUCB1XES TeSys U Advanced Control Unit 0.35-1.4 A 48 V AC Motor Starter Module

The Schneider Electric LUCB1XES is a TeSys U advanced control unit providing adjustable thermal-magnetic motor protection from 0.35 to 1.4 A plus diagnostic outputs. Plugged into an advanced LUB120, LUB320, or LUB380 power base, it forms a starter-controller with Class 10 overload tripping, phase-failure sensing, earth-fault detection, a thermal-alarm signal, and a test pushbutton 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 LUCB1XES brings the 48 V control option to the diagnostic-capable advanced unit line, covering 48 V AC and 48-72 V DC with one reference in the same 0.35-1.4 A band as the LUCB1XB and LUCB1XBL. It is the choice when the panel's control bus runs at 48 V and the application still needs the thermal-alarm output rather than just a bare trip contact.
