A switchboard takes an incoming supply and distributes it to outgoing circuits. ### A simple example Use OTKM404023PBL4R.STP.stp (revision B) to place the original solid geometry in your 3D assembly. The ZIP contains the unmodified OTKM404023PBL4R.STP.stp. ### What the drawings help you do Use OTKM404023PBL4R.STP.stp (revision B) to place the original solid geometry in your 3D assembly. The ZIP contains the unmodified OTKM404023PBL4R.STP.stp. ### Before using this reference - Match the recorded manufacturer configuration: OTKM404023PBL4RDD.stp, OT125GAUR3AZ, 1SCA148441R1001, OT125GAUR3TZ, 1SCA148442R1001, OT125GUUR3AZ, 1SCA148443R1001, OT125GUUR3TZ, 1SCA148444R1001, OT90GAUR3AZ, 1SCA148435R1001, OT90GAUR3TZ, 1SCA148436R1001, OT90GUUR3AZ, 1SCA148437R1001, OT90GUUR3TZ, 1SCA148438R1001, OT125GAUM3TZ, 1SCA161650R1001, OT90GAUM3TZ, 1SCA161656R1001 - The supplied model has approximate X × Y × Z bounds of 400 × 277.3 × 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: OTKM404023PBL4R.STP.stp — B. Use Documentation & sources to check for a newer issue. ### Which original files are supplied for OTKM404023PBL4RDD? 1 inspected original for ABB OTKM404023PBL4RDD: OTKM404023PBL4R.STP.stp (STEP).
