## In plain English

### What the equipment does

Switchgear groups the devices that connect, disconnect and protect power circuits. A switchboard takes an incoming supply and distributes it to outgoing circuits.

### A simple example

Use OT90-125GAUC6_Z_STEP.STP.stp (revision A) to place the original solid geometry in your 3D assembly.

### What the drawings help you do

Use OT90-125GAUC6_Z_STEP.STP.stp (revision A) to place the original solid geometry in your 3D assembly.

### Before using this reference

- Match the recorded manufacturer configuration: OT125GAUC6AZ, OT125GAUC6TZ, OT90GAUC6AZ, OT90GAUC6TZ, igs-file
- The supplied model has approximate X × Y × Z bounds of 403.5 × 682.2 × 280.1 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: OT90-125GAUC6_Z_STEP.STP.stp — A. Use Documentation & sources to check for a newer issue.
