Advantages

High-performance

- Extremely high breaking up to 300 kA.
- Very strong limitation of short-circuit currents (and therefore very sharp decrease in thermal and mechanical stress).
- Good resistance to cyclic loading.

Increased reliability

- Absolute protection over time guaranteed by the simplicity of manufacture and function (Joule effect).
- No degradation of fuse characteristics over time.

Improved safety

The energy released whilst eliminating the fault (fuse blowing) is contained within the cartridge (no degassing).

Fuse blown indicator

An auxiliary contact can be adapted to signal that a fuse has blown.

Applications

  • Industry - Protection for drives and motors
