High speed fuses (UR) protect power semi-conductors and DC circuits.
AdvantagesHigh level performances
• Very high breaking capacity up to 300 kA.
• Very high limitation of short-circuit currents (and therefore significant reduction in the thermal and mechanical stress).
• High resistance to cyclic loads.
High reliability
• Absolute protection over time guaranteed by the simplicity of manufacture and function (Joule effect).
• No downgrading of fuse characteristics over time.
Improved safety
The energy released whilst eliminating the fault (fuse blowing) remains contained within the cartridge (no degassing).
Fuse blown detection
An auxiliary contact can be adapted for fuse blown indication.
