## 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 OTDCB400F in microgrids, place the documented arrangement beside the adjacent equipment and compare its fixing and connection access with the source drawing. The supplied model spans 22.0 × 139.0 × 159.0 mm along its own X, Y and Z axes.

### What the drawings help you do

Use OTDCB400F.stp for OTDCB400F. STEP is the supplied editable 3D exchange file; the browser model is a simplified display preview. Match ABB document OTDCB400F.STP revision A when checking a replacement.

### Before using this reference

- Match the configuration named “OTDCB400F”; terminal direction, mounting version and pole options can change the outline.
- Use ABB document OTDCB400F.STP, revision A, to check the mounting and connection details before placing this item in the assembly.
- The supplied model spans 22.0 × 139.0 × 159.0 mm along its own X, Y and Z axes. These are model extents, not installation clearances.

### Which ABB source identifies OTDCB400F?
