The Meaning of the HS and SH Codes on Fuses
Model: (Various brands) Various
In this video, we can see what the codes "HS" or "SH" mean, which are sometimes printed on fuses: these refer to two different characteristics related to their interruption speed, that is, the response time, and their ability to withstand temporary overloads. "HS" means High Speed, indicating that the fuse is quick to interrupt the circuit in case of overcurrent; it is used in applications where immediate protection is required, such as in circuits with sensitive components (precision electronics or semiconductors). In other standards, they may be marked as FF (very fast acting) or F (fast). "SH" means Slow High Breaking Capacity, indicating a slow fuse but with a high capacity to interrupt high currents; it withstands brief overloads without blowing (useful for motors or transformers, where starting currents are high but temporary). In other standards, they may be referred to as "T" (Time delay) or Slow Blow.
