Core Engineering Advantages
1. Ultra-Fast, High-Limiting Fault Interruption
Microsecond Response: aR fuses interrupt fault currents within <10 ms (half-cycle), preventing thermal runaway in semiconductors by limiting peak currents (Iᴘᴇᴀᴋ) to 20% of prospective fault values. This reduces energy let-through (I²t) by 90% compared to circuit breakers .
