# ANSI/IEEE fuse-switch symbol

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

## Symbol convention

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

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

## What it represents

The fuse-switch form identifies a switching assembly involving a documented fuse element. The exact construction and operating arrangement belong to the product reference; drafting should retain both switching and protective meanings.
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 operating handle reference separate from the fuse-link tag.
- 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

- Identify fuse-switch assembly
- Name compatible links
- Show main connections

## Important distinction

A fuse-switch is not merely a differently drawn circuit breaker.

## Facts
