This is a pack of five Victron MEGA fuses, named as 300A/80V. The specification gives an 80 V voltage rating and a 225 A current rating. Across the fuse the approximate voltage drop is 110 mV, with a cold resistance of 0.235 mΩ. Victron makes MEGA-only fuse holders, including a six-way version, for fuses of this type.

Our take

The 225 A current rating in the specification sits below the 300A in the product name, so check which figure your wiring and fuse holder are sized to before relying on it. The 80 V rating and 110 mV approximate voltage drop are the other figures given.

From our buying guide

On a boat subpart I covers, each ungrounded output conductor from a battery needs a manually reset, trip-free circuit breaker or fuse within 72 inches of the battery.

Check before you buy:

  • On a boat subpart I covers, a continuously energized ungrounded terminal needs a boot, nipple, cap, cover or shield.
  • Ignition protection on a charger or switch is the maker's statement, so read what it says and which standard it names.
