Circuit Protection / Fuses / Disconnects > Fuses & Fuse Holders
Fuses & Fuse Holders
Fuses provide overcurrent or overload protection in an electrical circuit to prevent damage to the load or power source. Fuses are destructible devices, meaning once they have operated, they must be replaced. Fuses are available for current ratings from 1A to 1200A and in a wide selection of operating characteristics to fit specific needs.
Industrial Fuses, Fuse Holders and Fuse Blocks
Category Selection
Edison Fuse products are industry-standard fuses that are designed using the highest quality materials and manufacturing methods.
- All Edison fuses can be directly cross referenced and used as replacements for other name-brand fuses such as Littelfuse, Ferraz/Mersen, Siemens, and many more.
- See the manufacturer cross reference in our free product catalog. Voltage ranges offered are 250V to 600V fuses. Ampere ranges offered are 0.25A to 600A fuses.
- When selecting industrial Edison fuses, be sure to comply with any applicable PUBLIC SAFETY standards that apply to Over-current Protection Devices (OPD).
