Victron Energy MEGA-Fuse 400A/80V (5-Pack)

Heavy-Duty Bolt-Down Circuit Protection and High-Voltage Safety for 48V Power Grids: The commercial-grade Victron Energy MEGA-Fuse 400A/80V (Package of 5 pcs) is an elite, high-speed overcurrent safety solution engineered to safeguard demanding, high-amperage DC networks. Sized with a robust 400 Amp continuous current rating and an expanded 80V DC voltage window, these premium ceramic fuses operate with an ultra-low cold resistance of $0.128\text{ m}\Omega$ to prevent unwanted power losses while maintaining a minimal inline voltage drop of just $80\text{ mV}$. This bolt-down MEGA format features 10mm connection tabs with M8 clearance holes, ensuring a rock-solid, vibration-resistant connection inside Lynx distribution blocks or modular fuse holders. It is designed to safely shrug off severe inductive startup loads without nuisance blowing, functioning as an indispensable defensive cornerstone to shield large inverters, battery banks, and charge controllers within integrated lithium power systems. Having five field-ready spares on hand ensures code-compliant, rugged system reliability built specifically to secure high-output storage arrays powered by industrial 48V lithium batteries and heavy-duty LiFePO4 lithium batteries.
