A fused switch combines a switching function with fuse protection.

## What it represents

A fused switch combines a switching function with fuse protection. The schematic should retain both functions so the fuse rating is not confused with the switch's operational rating.

## How to read it

- Check whether the selected assembly moves the fuse carrier as part of its operation.
- 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

- Identify fuse-link type
- State switch utilization category
- Show fuse carrier and poles

## Important distinction

A switch with separate series fuses and a fuse-switch can have different mechanical constructions.

## Facts
