Current Rating: Match semiconductor I₂t tolerance-typically 1.5–2× device rating (e.g., 500A fuse for 300A IGBT) .
Breaking Capacity: Ensure kAIC exceeds prospective fault current (e.g., 80 kA for transformer-fed systems) .
Why NH aR Outperforms Alternatives?
vs. gG Fuses: gG fuses respond too slowly for semiconductors and cannot limit Iᴘᴇᴀᴋ effectively .
vs. Circuit Breakers: Breakers take 20–50 ms to act-enough time to destroy IGBTs .
