A switchboard takes an incoming supply and distributes it to outgoing circuits. ### A simple example Use OTKM104023PBL.STP.stp (revision E) to place the original solid geometry in your 3D assembly. ### What the drawings help you do Use OTKM104023PBL.STP.stp (revision E) to place the original solid geometry in your 3D assembly. ### Before using this reference - Match the recorded manufacturer configuration: OTKM104023PBL.stp OKL570N3YF3UU0N 1SCA152275R1001 OKL570N4YF3UU00 1SCA152276R1001 OKL720N3YF3UU0N 1SCA152277R1001 OKL720N4YF3UU00 1SCA152278R1001 OT630KLUU3AZ 1SCA022549R2510 OT630KLUU3BLZ 1SCA105753R1001 OT630KLUU3BZ 1SCA022750R1510 OT630KLUU4BLZ 1SCA125038R1001 OT630KLUU4BZ 1SCA022830R4490 OT800KLUU3BAZ 1SCA140695R1001 OT800KLUU3BLZ 1SCA111208R1001 OT800KLUU3BZ 1SCA022750R1600 OT800KLUU4BLZ 1SCA115450R1001 OT800KLUU4BZ 1SCA022830R4570 - The supplied model has approximate X × Y × Z bounds of 404 × 1077 × 282.3 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: OTKM104023PBL.STP.stp — E.
