Compact high speed fuse

Use up to 48% less enclosure space

Eaton answers the call for compact drives, power conversion and UPS equipment with our new Bussmann series compact high speed fuses.

Our 50-400 amp fuses use up to 48% less enclosure space when compared with traditional high speed, round body fuses. What’s more, the innovative design allows for a significantly smaller package without compromising heat rise performance.

With the most compact high speed fuses in the industry, rated at 500Vac/dc, we help you achieve smaller overall equipment designs.

These interactive melting and clearing curves can be modified using the selectable parameters in the dropdown menus that appear under each curve.

Select as many parameters you want covering temperature and thermal correction factor, force air cooling, load current frequency, altitude correction factor and fuse load constant.

If you wish to see a curve for a single fuse amp rating, you may deactivate the other curves by clicking on the unwanted catalog numbers at appear in the list on the right hand side.

Please note fuses should not be specified for operating below their minimum interrupting rating. See data sheet No. 10414 for details.
