A switchboard takes an incoming supply and distributes it to outgoing circuits. ### A simple example Use OTKM402518PC.STP.stp (revision B) to place the original solid geometry in your 3D assembly. ### What the drawings help you do Use OTKM402518PC.STP.stp (revision B) to place the original solid geometry in your 3D assembly. ### Before using this reference - Match the recorded manufacturer configuration: OTKM402518PC.stp OT125GLCC3BZ 1SCA148273R1001 OT125GLCC4BZ 1SCA148275R1001 OT160EVLCC3BZ 1SCA148265R1001 OT160EVLCC4BZ 1SCA148268R1001 OT125GLCC3AZ 1SCA148211R1001 OT125GLCC3TZ 1SCA148212R1001 OT125GLCC4AZ 1SCA148213R1001 OT125GLCC4TZ 1SCA148214R1001 OT90GLCC3AZ 1SCA148203R1001 OT90GLCC3TZ 1SCA148204R1001 OT90GLCC4AZ 1SCA148205R1001 OT90GLCC4TZ 1SCA148208R1001 - The supplied model has approximate X × Y × Z bounds of 250 × 227.3 × 483 mm. These are source-model axes; mounting holes and installation clearances must come from the matching manufacturer sheet. - The orthographic views are projected from the manufacturer 3D geometry. They are labelled separately from original dimensioned sheets and do not add manufacturer dimensions. - The source was checked on 2026-11-11; recorded file revisions: OTKM402518PC.STP.stp — B. Use Documentation & sources to check for a newer issue. ### Which original files are supplied for OTKM402518PC? 1 inspected original for ABB OTKM402518PC: OTKM402518PC.STP.stp (STEP).
