Socomec 170M6814 High Speed Fuse (uR) 690V 1000A aR Protection Type

Socomec, 170M6814, High-Speed Fuse (uR) S3, DIN43620, 200kA, 690V, 1000A aR Protection Type

Features:

• 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 operated

Application:

• To protect power semiconductors (variable speed drives, inverters, etc.)

Extended range

• Compatible range of devices (Fuserbloc, load break switches, fuse bases)

Conformity to standards

• IEC 60269-1
• NF EN 60269-1
• IEC 60269-4
• NF EN 60269-4
• DIN EN 60269-4

High speed fuses (uR) protect power semiconductors and DC circuits.
