# IEC fused switching form: power auto switch/disconnect Canonical URL: https://eloragrid.ai/symbols/iec-fused-switching-form-power-auto-switch-disconnect Publisher: Elora Grid Updated: 2026-10-28 Lookup label: QS Drawing use: Schematic Reference families: IEC, Manufacturer ## Symbol convention Convention: IEC Form: Power Auto Switch/Disconnect Autodesk IEC-60617 Symbol Preview: Disconnect 1 Pole, HDS11Q5 / VDS11Q5. This identifies the publisher's library context; exact IEC graphics and database identities are not asserted. Fused switching form form: Power Auto Switch/Disconnect. ## In plain English ### What does IEC fused switching form: power auto switch/disconnect mean? A fused switching form identifies a switch and a fuse within the documented arrangement. Switching load current, providing isolation and interrupting a fault are separate capabilities, and the drawing must show which element performs each role. This entry identifies the power auto switch/disconnect form in the publisher's IEC-context family. ### A simple example An outgoing panel feeder can show a fused switch with its operating handle and fuse reference. Keep the switching tag linked to the fuse schedule so replacement protection and the intended switching duty can be checked together. ### What the drawings help you do The family name does not establish a device utilization category or prove that a fuse carrier may be moved under load. Use the selected assembly documentation for load operation, isolation indication, fuse class and any interlocks. ### This particular reference Fused switching form form: Power Auto Switch/Disconnect. This entry adds the power auto switch/disconnect detail to the broader fused switching form family. The family name does not establish a device utilization category or prove that a fuse carrier may be moved under load. Use the selected assembly documentation for load operation, isolation indication, fuse class and any interlocks. ### Terms - Rating: A value stating the conditions for which equipment is specified. - Schematic: A drawing showing function and connections rather than physical appearance.

Keep the switching tag linked to the fuse schedule so replacement protection and the intended switching duty can be checked together. - The family name does not establish a device utilization category or prove that a fuse carrier may be moved under load. Use the selected assembly documentation for load operation, isolation indication, fuse class and any interlocks. ## Information to show or reference - Identify the switching element and associated fuse references. - State whether the device switches load current and provides isolation. - Reference fuse class, current rating and operating instructions. ## Important distinction This entry adds the power auto switch/disconnect detail to the broader fused switching form family. The family name does not establish a device utilization category or prove that a fuse carrier may be moved under load. Use the selected assembly documentation for load operation, isolation indication, fuse class and any interlocks. ## Facts - Drawing form: Power Auto Switch/Disconnect - Public vendor block names: HDS11Q5 / VDS11Q5.
