Side-by-side reference

Understand the difference.

Compare the meaning, drawing context and source references of two entries. A similar graphic or shared abbreviation does not establish equivalence.

SW FUSE

IEEE / ANSI

ANSI/IEEE fused switch symbol

The fused-switch form keeps a fuse protective element associated with a switching path. Read the switch and fuse ratings independently, then follow the device tag to the complete assembly and replacement fuse schedule.

Drawing use: SLD / Schematic
Application: Power distribution
Reference family: IEEE / ANSI / Manufacturer
Form evidence: Autodesk IEEE-oriented Fusible Disconnects 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.

A distinction that matters

A combined fused-switch form is different from a bare fuse symbol and from a circuit breaker.

SW FUSE

Symbols

Fused switch

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.

Drawing use: SLD / Schematic
Application: Power distribution
Reference family: IEC / Manufacturer

A distinction that matters

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