Schneider Electric LU2B12B TeSys U Reversing Power Base 3P 12 A 24 V AC Coil Motor Starter Module

The Schneider Electric LU2B12B is a TeSys U standard reversing power base, 3-pole, rated 12 A at up to 440 V, that forms a complete reversing starter-controller once fitted with a LUC control unit and the matching 24 V AC 50/60 Hz reverser module.

Selection Notes

The 12 A rating sets the motor size this power base can reverse; pick a LUC control unit from LUC.05B, LUC.12B, LUC.1XB, LUC.X6B to match the thermal/electronic protection class needed, since the power base alone has no overload protection of its own. The 24 V AC 50/60 Hz reverser module must match the control transformer already feeding the panel — the power contacts, rotary handle and mounting are identical across every control-voltage variant of this base, only the coil input changes. The padlockable rotary handle gives a lockout-tagout isolation point that a plain contactor pair wired for reversing does not provide.
