Selection Notes
This base must be completed with a compatible LUC control unit (LUC.X6BL, LUC.1XBL, LUC.05BL or LUC.12BL) to form a working reversing starter-controller — certification applies only to that combination. It already includes the LU2MB0BL reverser module wired for 24 V DC, 1 NO + 1 NC auxiliary signalling contacts and blanking shutters over unused cavities, so the only sizing decision left is matching the control unit's protection range to the motor's full-load current.
