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