Victron 225A/80V MEGA Fuse for Lynx (package of 5 pcs)

The Victron MEGA Fuse 225A/80V is a high-current ceramic blade fuse designed for overcurrent protection in 12V, 24V, and 48V DC distribution systems. Sold in a pack of five, it is compatible with Victron's range of MEGA fuse holders as well as the Lynx Distributor — where MEGA fuses provide individually fused connections for batteries, chargers, and DC loads within the Lynx Distribution System.

The 80V voltage rating makes this fuse suitable for use across the full range of Victron system voltages, from 12V lead-acid and lithium battery banks through to 48V high-energy storage installations. At a rated current of 225A, it provides appropriate overcurrent protection for high-capacity circuits such as large inverters, inverter/chargers, and paralleled battery strings where fault currents must be interrupted rapidly and reliably.

MEGA fuses offer a visual blown indicator, making it easy to identify a blown fuse by inspection without the need for a multimeter. Their ceramic construction provides robust performance in high-current interruption events, and their low cold resistance of 0.235 mΩ minimises voltage drop and heat generation at rated current — preserving system efficiency in continuous high-load operation.

As a consumable spare part, the 5-pack format ensures a ready supply of replacement fuses is always available on board or on site — particularly important in remote marine, RV, and off-grid installations where obtaining a replacement quickly may not be possible.

Features

80V Voltage Rating — Suitable for 12V, 24V, and 48V Systems

The 80V DC voltage rating makes this MEGA fuse suitable for use in systems operating at any standard Victron voltage — 12V, 24V, or 48V — without the need to select a voltage-specific fuse, simplifying spare parts management for multi-voltage installations.

225A Rated Current for High-Capacity Circuit Protection

Rated at 225A continuous, this fuse provides appropriate overcurrent and short-circuit protection for large inverters, inverter/chargers, solar chargers, and battery string connections in demanding energy storage installations.

Compatible with Lynx Distributor and MEGA Fuse Holders

Designed to fit Victron's single MEGA fuse holder, six-way MEGA fuse holder, and modular MEGA fuse holder with optional busbar accessory — as well as the Lynx Distributor module, where MEGA fuses provide individually monitored fused connections for each circuit in the Lynx Distribution System.

Visual Blown Fuse Indicator

Each MEGA fuse features a visual indicator window that shows clearly when the fuse element has blown — enabling rapid identification of a blown fuse by visual inspection alone, without requiring a multimeter or removing the fuse from its holder.

Low Resistance for Minimal Voltage Drop

With a cold resistance of just 0.235 mΩ and an approximate voltage drop of 110 mV at rated current, the MEGA 225A/80V fuse minimises energy loss and heat generation at the fuse connection — maintaining system efficiency in continuous high-current operation.

Ceramic Construction for Reliable High-Current Interruption

The ceramic fuse body provides reliable interruption of high fault currents without risk of arc flash or enclosure damage, making MEGA fuses a safe and dependable choice for battery system overcurrent protection in automotive, marine, and industrial DC installations.

Sold in a Pack of Five

Supplied as a pack of five fuses, providing a ready supply of replacement fuses for ongoing maintenance and emergency use — particularly valuable in remote off-grid, marine, and vehicle installations where sourcing a replacement quickly may not be practical.
