Schneider Electric LUCBX6BL TeSys U Advanced Control Unit 0.15-0.6 A 24 V DC Motor Starter Module

The Schneider Electric LUCBX6BL is a TeSys U advanced control unit providing adjustable thermal-magnetic motor protection from 0.15 to 0.6 A plus diagnostic outputs, the finest current band in the advanced control-unit range. 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 0.09 kW at 400 V, controlled from a 24 V DC supply.

Selection Notes

The LUCBX6BL adds the thermal-alarm output and test pushbutton to the finest 0.15-0.6 A protection band, useful on small motors where early-warning diagnostics still justify the extra wiring over the plain LUCAX6BL. It shares the 0.09 kW rating and Class 10 curve of its non-diagnostic sibling, so the alarm feature is the only differentiator. Only the 24 V DC coil is currently listed for this current band in the advanced line.
