FAQ
Q: What is a high-speed fuse?
A: High-speed fuses, or semiconductor fuses, are fuses that operate very fast and can be used to protect semiconductor components.
Q: How are high-speed fuses different from other fuses?
A: Unlike industrial fuses, the protective features of high-speed fuses are designed to minimize I²T, peak current let-through, and arc voltage.
Q: What are the main styles of semiconductor fuses?
A: The most common styles of high-speed fuses are: North American round body/ Square body/ Cylindrical or Ferrule/ BS88 bolted.
