It is designed to protect against both overload currents (the ‘g’) and short-circuit currents, making it suitable for protecting cables and general equipment.</p> <strong>Is this fuse suitable for protecting semiconductor devices?</strong><br><p>No, gG fuses are not fast-acting enough to protect sensitive semiconductor devices like thyristors, diodes, or IGBTs. For those applications, you should use ultra-rapid fuses with ‘aR’ or ‘gS’ characteristics.</p> <strong>What is the significance of the 120 kA breaking capacity?</strong><br><p>The 120 kA (kiloamperes) breaking capacity is the maximum fault current that the fuse can safely interrupt without rupturing or causing a hazard. This high rating ensures safety in industrial systems where potential short-circuit currents can be very large.</p> </p> <p>Last Update: Friday, March 13, 2026</p> <p><em>profideals is not an authorized distributor, reseller, or representative of the products featured on this website.
