An additional pole is a separately drawn part of a multipole circuit breaker.

## What it represents

An additional pole is a separately drawn part of a multipole circuit breaker. Parent and child representations retain a shared device identity while allowing the phase conductors to appear on separate schematic lines.

## How to read it

- Verify common operation and the shared breaker tag across all poles.
- The preview is an original explanation of this function. Match the actual drawing convention to its legend and the selected equipment documentation.

## Information to show or reference

- Match parent device tag
- Identify pole terminal numbers
- Show common mechanical operation

## Important distinction

A second schematic pole is not a second independently operated breaker.

## Facts

- Drawing role: Circuit interruption
- Representation scope: Functional concept; not an official standard graphic or a product footprint
- Public vendor block reference: HCB2, VCB2 (Autodesk identifiers; not IEC symbol numbers)
- Identifier status: The short label is a functional lookup label, not an assigned IEC or IEEE symbol number. Any separately listed Autodesk code is a verified vendor block name.
