# ANSI/IEEE fuse symbol

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

## Symbol convention

Convention: IEEE / ANSI
Form: Autodesk IEEE-oriented Fuses 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: [Fuse](https://eloragrid.ai/symbols/fuse)

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

## What it represents

The fuse representation identifies a sacrificial protective element in a conductor path. The drawing requires its fuse designation and selected link data; a compact outline cannot establish the time-current category, voltage rating or breaking capacity.
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

- Trace the conductor through the protective element rather than treating its outline as a terminal.
- 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 fuse category
- Record current/voltage rating
- Reference breaking and coordination data

## Important distinction

A fuse graphic represents a fuse-link function; a fuse-switch includes an operating assembly as well.
