Emergency Protective Devices TRIZ Cases
- Bypass Contact Switch Circuit for Arc and Bounce Reduction
A bypass contact creates a parallel current path and elastic cushioning to cut arcing, bounce, and contact damage during switch closure.
- Spacer-Supported Fuse Structure for Fast Arc Extinction
A cooled-wall fuse uses insulated spacers and sand-filled reduced sections to interrupt high-energy overcurrents quickly while limiting leakage current.
- Adjustable Fuse Holder Assembly for Covered Bolt-Down Fuse Mounting
A movable-tab fuse holder covers exposed studs, supports varied fuse spacing, and organizes cabling to reduce short-circuit risk.
- Encapsulated Arc-Quenching Fuse for Localized Arc Suppression
Encapsulated liquid vials rupture at fuse weak spots to cool arc plasma locally, cutting sealing complexity, size, and material waste.
- Wave-Shaped Fuse Element for High-Voltage Compact Casing
A wave-shaped fuse element with crest cutouts fits easily in the casing while supporting high voltage and current without enlarging the housing.
