The Schneider Electric LU6MB0BL is a TeSys U reverser block for side mounting, rated 38 A at 690 V with a 24 V DC coil, adding reversing contacts and interlocking to an advanced LUB120, LUB320, or LUB380 power base fitted with a LUC*BL control unit. Combined with an LU9MR1 assembling connector and LU9M1 terminal block, it completes a side-mounted reversing starter-controller.
The LU6MB0BL extends the side-mounted reverser block range to 38 A and to the LUB380 base, which the lower-current LU6MB0B does not cover. Its 24 V DC coil draws only 120 mA holding current against 2360 mA for the AC-coil LU6MB0B, a relevant difference when sizing the upstream control relay. Choose the vertical LU2MB0BL instead where panel depth favors vertical stacking over side mounting.
