## 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

When coordinating OT200...OT250U02 in switchgear, place the documented arrangement beside the adjacent equipment and compare its fixing and connection access with the source drawing. The supplied model spans 170.0 × 82.5 × 126.5 mm along its own X, Y and Z axes.

### What the drawings help you do

Use OT200_250U02_1SCC307634F0001.dxf (DXF) to read the supplied 2D drawing, and OT200_250U02.stp (STEP) for the 3D layout. Both manufacturer source titles identify OT200...OT250U02. Match the document and revision shown on each file before coordinating the selected equipment.

### Before using this reference

- Match the configuration named “OT200...OT250U02”; terminal direction, mounting version and pole options can change the outline.
- Use ABB document OT200-250U02.STP, revision A, to check the mounting and connection details before placing this item in the assembly.
- The supplied model spans 170.0 × 82.5 × 126.5 mm along its own X, Y and Z axes. These are model extents, not installation clearances.
- The 2D source is ABB document 1SCC307634F0001, revision A. Check its fixing and connection details against the STEP geometry.

### Which ABB source identifies OT200...OT250U02?

The acquired file is OT200_250U02.stp, document OT200-250U02.STP, revision A. The manufacturer source and pinned original link appear below.

### Does the preview establish installation clearances?

No. The supplied model spans 170.0 × 82.5 × 126.5 mm along its own X, Y and Z axes. Use the installation requirements for OT200...OT250U02 and the selected assembly to reserve cable and service access.

### Terms

- CAD: Computer-aided design files used to prepare drawings and models.
