The Victron Energy MEGA-fuse holder is a single-fuse housing built to accept standard MEGA-format fuses across 12V, 24V and 48V DC systems. It gives a secure, accessible fuse point wherever a high-current DC circuit needs one, from battery banks to inverter connections and busbar protection.

Key features of the victron mega fuse holder

• Fuse format, accepts standard MEGA-fuses, compatible with the full Victron MEGA-fuse range.
• System voltage, suitable for 12V, 24V and 48V DC installations.
• Weight, 0.11 kg, easy to fit into confined enclosures or battery compartments.
• Housing, compact design keeps the fuse accessible for inspection and replacement.
• Supply, sold individually so installers can specify exactly the number of fuse points needed.

Why the right holder matters

MEGA-fuses are a common format in automotive and marine DC protection, rated for high continuous currents. This holder gives the correct mechanical and electrical interface for those fuses, keeping a low-resistance, vibration-resistant connection at the terminals. A poorly matched holder adds resistance and heat at the fuse point, which can cause nuisance tripping or damage the fuse before a real fault occurs. This is the standard Victron housing used throughout their inverter, charger and battery installations. It's sold without a fuse, so the correct MEGA-fuse rating needs to be chosen separately based on circuit current and cable sizing.

Applications

• Inverter DC input protection in off-grid and battery backup systems.
• Battery bank fusing in 12V, 24V and 48V installations.
• Marine and motorhome DC distribution boards.
• Busbar and cable protection in high-current DC circuits.
• Adding or replacing fuse points in existing Victron installations.

What's in the box

• 1 x MEGA-fuse holder (fuse not included)

Installation notes

Fit this holder as close to the positive battery terminal as practically possible to minimise unprotected cable length. Match the fuse rating to the cable cross-section and the maximum continuous current of the connected equipment. Installation should be carried out by a qualified electrician or an experienced installer familiar with DC protection requirements.
