A reactor is an inductive component used for a documented power-circuit purpose.

## What it represents

A reactor is an inductive component used for a documented power-circuit purpose. Its connection and rated electrical characteristics need to be stated because an inductor outline alone does not identify its duty.

## How to read it

- Identify whether it is connected in series or shunt.
- 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

- State circuit purpose
- Record inductance or impedance
- Reference current and voltage rating

## Important distinction

A reactor stores magnetic energy; a transformer couples separate documented winding circuits.

## Facts

- Drawing role: Inductive component
- Representation scope: Functional concept; not an official standard graphic or a product footprint
- Public vendor block reference: HRT1, VRT1 (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.
