Common information about the industrial fuse markings.
Industrial fuses among other fuses have various intended uses and because and as a result they have few different parameters, which can vary between fuses. Here is a list and explanation of the most important parameters according to the IEC 60269 standard:

• Typical fuse speed markings:
  • Extremely fast acting:
    • aR:
      • Partial-range breaking capacity (short-circuit protection only) for the protection of Power Semiconductors.
    • gR:
      • Full-range breaking capacity (overload and short-circuit protection) for the protection of Power Semiconductors or rectifiers.
  • Fast acting:
    • gG:
      • Full-range breaking capacity (overload and shortcircuit protection) for general applications.
    • gL:
      • Same as gG (old marking practice).
    • gM:
      • Full-range breaking capacity (overload and shortcircuit protection) for the protection of motor circuits.
    • gPV:
      • Protection of solar photovoltaic arrays.
  • Slow acting:
    • aM:
      • Partial-range breaking capacity (short-circuit protection only) for the protection of motor circuits.
  • Less common markings:
    • gS:
      • Full-range breaking capacity (overload and short-circuit protection) for the protection of batteries & power semiconductors in drives.
    • gB:
      • Full-range breaking capacity (overload and shortcircuit protection) robust for mining application.
    • gTr:
      • Full-range breaking capacity (overload and shortcircuit protection) for protection of transformers.
    • gRL:
      • Full-range breaking capacity (overload and short-circuit protection) for the protection of Power Semiconductors, Line & Cable Protection.
    • gN:
      • Conductors sized to North American practice
• Fuse breaking capacity:
  • Typically indicated in kA (kiloamperes, ie in thousands of amperes). This value means that the fuse is capable of break the xkA amount of current generated by short circuit/fault condition and as an outcome fuse will successfully extinguish the arc inside the fuse.
