MEGA-fuse 500A/80V — this is the ultimate power fuse from Victron Energy, created to protect the most powerful direct current (DC) systems. The element is capable of passing a colossal 500 Amperes in normal mode, ensuring an instant circuit break in the event of an accident or short circuit. It supports voltage up to 80 V, making it an ideal solution for modern 48-volt systems (as well as 12 and 24 V).
This device is the foundation of safety when designing systems with multiple powerful inverters, industrial charging nodes, and main battery layouts, where zero energy losses are required.
Key Pros of the MEGA-fuse 500A Fuse
- Limit current: 500A, allowable voltage — up to 80 VDC
- Phenomenally low resistance: 0.10 mOhm — complete absence of heating in the contact zone
- Voltage drop of no more than 80 mV — saves every watt from the batteries
- Uncompromising protection against short circuits
- Standard MEGA size — compatibility with branded holders and distribution blocks
- Strong and reliable installation
- Official quality guarantee from Victron Energy — for the most critical nodes
Technical Nuances
- Fusible jumper — physical destruction of the element when the current is exceeded gives a 100% guarantee of breaking the circuit and saving the equipment
- Cold resistance (0.10 mOhm) — withstands huge surges in consumption from heavy electric motors or compressors
- Ideal selectivity — easily fits into the protection architecture of large solar power plants
Fields of Operation
- Protection of main busbars in large-scale battery storage
- Tying clusters of several Victron Quattro inverters
- Industrial backup systems (ESS)
- Equipment of cruise yachts and work boats
- Powerful motorhomes, where protection of power lines from overheating is required
What to Combine With
- MEGA Fuse Holder — insulated and safe holder
- DC Distribution 250 — direct current distribution block
- BatteryProtect — smart module for disconnecting discharged batteries
- Victron Smart Battery Shunt — precision ammeter up to 1000 A
