Symbols

Fuse-switch

A fuse-switch uses a fuse-link or fuse carrier as part of its moving switching contact system. The equipment designation must identify the actual assembly rather than treating every fused switch as mechanically identical.

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

A distinction that matters

Fuse-switch describes the moving contact construction; a fused switch is a broader functional description.

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.
