NGT00 Semiconductor Fuse Applications
NGT00 Semiconductor Fuse FAQs
1、What is the difference between a semiconductor fuse and an HRC fuse?
A semiconductor fuse, such as the GRL NGT00, is designed to react much faster than a standard HRC (High Rupturing Capacity) fuse. Semiconductor fuses protect sensitive electronic components, such as IGBTs and diodes, clearing faults in milliseconds to prevent device damage. HRC fuses, on the other hand, are general-purpose fuses used for broader electrical protection in power distribution systems. In short, a semiconductor fuse is a fast-acting subset of HRC fuses, specifically designed to protect electronic devices rather than general power circuits.
2、 How do I select the right NGT00 fuse rating for my application?
To choose the correct fuse, match its rated voltage and current to your equipment’s operating parameters, ensuring the fuse can handle normal load current while reacting quickly under fault conditions. For semiconductor circuits, select a fuse with an aR protection class, high I²t withstand, and breaking capacity ≥ 100kA for optimal safety. GRL’s technical team can assist with detailed selection based on your system’s specifications.
3、How do I check if an NGT00 fuse has blown?
Disconnect power and use a multimeter to measure continuity across the fuse terminals. A functioning fuse shows near-zero resistance, while a blown fuse shows infinite resistance (open circuit). Always replace a blown fuse with the same model and rating to maintain system integrity.
