A gapped-core inductor includes a documented air gap in its magnetic circuit.

## What it represents

A gapped-core inductor includes a documented air gap in its magnetic circuit. The drawing identifies that construction while the component data establishes inductance and operating limits.

## How to read it

- A core gap marker describes the magnetic circuit, not an electrical disconnect.
- 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 inductance
- Reference current rating
- Identify gap/core construction

## Important distinction

A magnetic air gap is different from an open power-circuit connection.

## Facts

- Drawing role: Inductive component
- Representation scope: Functional concept; not an official standard graphic or a product footprint
- Public vendor block reference: HRT1L3, VRT1L3 (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.
