# ANSI/IEEE iron-core reactor symbol

Canonical URL: https://eloragrid.ai/symbols/ansi-iron-core-reactor
Publisher: Elora Grid
Updated: 2026-10-14
Lookup label: L IRON
Drawing use: SLD, Schematic
Reference families: IEEE / ANSI, Manufacturer

## Symbol convention

Convention: IEEE / ANSI
Form: Autodesk IEEE-oriented Reactors functional form
Autodesk explicitly publishes this block under IEEE Symbol Preview. The counterpart is the matching functional concept; no equivalence of every detailed standard graphic is asserted.
Related representation: [Iron-core reactor](https://eloragrid.ai/symbols/iron-core-reactor)

IEEE-oriented graphical reference for iron-core reactor, with public vendor evidence and drawing-reading notes.

## What it represents

The iron-core reactor form adds a magnetic-core construction qualifier to the inductive component. The modifier needs equipment data for current range and magnetic behaviour rather than an assumption that inductance stays constant under every condition.
This is a convention-specific lookup based on the publisher's IEEE-labelled preview. The geometry here is independently drawn to explain the connection or operation; it is not a certified reproduction of the standard graphic.

## How to read it

- Keep the magnetic qualifier attached to the identified winding.
- Read the selected library and the project legend together. A vendor block identifier is meaningful within its named library and is not a universal standard-symbol code.

## Information to show or reference

- State inductance/impedance
- Record current rating
- Reference core operating limits

## Important distinction

An iron-core reactor and an air-core reactor are different constructions, not different page orientations.
