L IRON
Iron-core reactor
An iron-core reactor uses a documented magnetic core to provide its inductive characteristic.

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