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

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.

Symbols

Fuse

A fuse representation identifies a protective fuse link in a circuit. Its rating and operating characteristics are additional information: a generic fuse mark does not specify utilization category, current, voltage, breaking capacity or coordination with other protective equipment.

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

A distinction that matters

A fuse and a fused disconnector may share protective components, but the assembly also includes a switching or isolation function.
