xMEGA-Fuse 225A/80V (Pack of 5) — CIP138225020
The Victron Energy MEGA-fuse 225A/80V is a high-current blade-style fuse designed to protect DC wiring in battery systems, inverters and other high-current 12V, 24V and 48V DC applications. Sold in a pack of five, this fuse is a standard consumable for professional solar and off-grid installations.
Key Features
- 225A continuous current rating, suitable for high-load DC circuits in battery and inverter systems.
- 80V DC maximum voltage rating, compatible with 12V, 24V and 48V battery banks.
- MEGA-fuse format, a widely used standard in automotive and marine DC protection applications.
- Pack of 5 fuses, providing spares for commissioning, servicing and ongoing maintenance.
- Lightweight at 45g per pack, easy to carry as part of an installer's standard kit.
- Compatible with standard MEGA fuseholders, including Victron's own MEGA fuseholder range.
Product Overview
MEGA-fuses are a bolt-down blade fuse format commonly used to protect the main DC cables between battery banks and inverters, charge controllers or busbars. At 225A, this fuse is suited to systems where the continuous DC current draw is high, such as large inverter installations or multi-battery configurations. The 80V DC voltage rating covers the full range of standard lead-acid and lithium battery voltages up to 48V nominal.
Fuse sizing is critical in DC systems. An incorrectly rated fuse either fails to protect the cable under fault conditions or nuisance-trips under normal load. The 225A rating should be selected based on the cable cross-section being protected and the maximum continuous current of the connected equipment. Always refer to the cable manufacturer's current rating and the inverter or charger documentation when specifying fuse size.
Buying in a pack of five makes practical sense for installers working across multiple sites or commissioning larger systems where more than one fuse position is required. It also ensures a spare is available on-site during initial commissioning and fault-finding.

Installation Notes
MEGA-fuses must be installed in a compatible MEGA fuseholder rated for the voltage and current of the circuit. Ensure the fuseholder and connecting cables are correctly rated for 225A continuous DC current before installation. DC wiring in battery and inverter systems carries significant fault energy and should be installed by a qualified electrician or MCS-accredited installer. Always isolate the battery bank before replacing or inspecting fuses.
