Victron Energy MEGA fuse 40A-500A black 48V (80V max)
The 80V version of the Victron Energy MEGA fuses, for 48V systems and any installation where battery voltage exceeds 32V. From 40A to 500A, in the Victron pack of 5 or as a single piece on the most requested ratings.
Key strengths
It protects the cable, not the load
A fuse is always sized on the cross-section of the cable it protects: it trips before the conductor reaches a dangerous temperature during a short circuit.
Bolt-down mounting
Direct screw contact on the busbar or fuse holder: no springs, no sliding contacts, minimal contact resistance even at high currents.
High breaking capacity
Designed for the short-circuit values typical of lithium and lead-acid battery banks, where fault currents quickly exceed several thousand amps.
Pack of 5 pieces
Victron supplies these fuses in packs of 5. On our site you can choose either a single piece or the full pack, at the Victron list price.
How to pick the rating
A 48V installation needs the 80V version: the 32V MEGA is not suitable.
- Work out the maximum continuous current the cable will carry
- Pick a fuse rated above the working current but below the cable's capacity
- Check the fuse voltage rating suits the system: a 32V fuse must not be used on a 48V installation
- Always fit the fuse as close as possible to the battery positive terminal
