A switchboard takes an incoming supply and distributes it to outgoing circuits. ### A simple example Use OTLK201510S25.IGS.stp (revision A) to place the original solid geometry in your 3D assembly. The ZIP contains the unmodified OTLK201510S25.IGS.stp. ### What the drawings help you do Use OTLK201510S25.IGS.stp (revision A) to place the original solid geometry in your 3D assembly. The ZIP contains the unmodified OTLK201510S25.IGS.stp. ### Before using this reference - Match the recorded manufacturer configuration: OTLK201510S25.stp, OT16ETMM3AE, 1SCA022742R0780, OT16ETMM3AEH, 1SCA022807R0720, OT16ETMM3TE, 1SCA022734R5980, OT16ETMM6TE, 1SCA022739R3870, OT16ETMM8TE, 1SCA022809R4230, OTL16A3M, 1SCA022612R8750, OTL16A3MH, 1SCA022774R0510, OTL16A4M, 1SCA022612R9130, OTL16A6M, 1SCA022612R9560, OTL16B3M, 1SCA022562R1260, OTL16B4M, 1SCA022562R4120, OTL16B6M, 1SCA022562R1690, OTL16BA3M, 1SCA022562R1850, OTL16BA4M, 1SCA022562R2070, OTL16BA6M, 1SCA022562R2230, OTL16BL3M, 1SCA102877R1001, OTL16BL4M, 1SCA102879R1001, - The supplied model has approximate X × Y × Z bounds of 150 × 139.8 × 200 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: OTLK201510S25.IGS.stp — A.
