Victron 80V 325A CNN Fuse for Lynx Shunt

Victron CNN 325A/80V Fuse: Precision Overcurrent Protection for Lynx Shunt Systems

Engineered Safety for High-Current DC Distribution

The Victron CNN 325A/80V fuse is a purpose-built overcurrent protection device designed to integrate seamlessly with the Victron Lynx Shunt module. As part of a modular DC distribution system, this fuse safeguards your investment against short circuits and excessive current draw, reducing the risk of thermal runaway, equipment damage, and system downtime. Its 325 A rating and 80 V DC compatibility make it suitable for demanding 12V, 24V, and 48V battery banks commonly found in off-grid solar, marine, and automotive applications.

Unlike generic automotive fuses, the CNN form factor offers a compact footprint with exceptionally low resistance, minimising voltage drop across the connection. This is critical in systems where every millivolt counts, such as lithium battery installations with high inrush capabilities. The fuse's fast-acting characteristic ensures a rapid response to fault conditions, protecting downstream Victron inverters, chargers, and MPPT controllers.

Key Features

• 325 A current rating for high-demand DC circuits
• 80 V DC maximum voltage suitable for 12V, 24V, and 48V systems
• CNN form factor with forked terminals for secure bolted connections
• Transparent inspection window for quick visual status checks
• Reinforced composite housing for thermal stability and electrical insulation
• Direct fit for Victron Lynx Shunt no adapters required

Why the Right Fuse Matters in a Lynx System

The Victron Lynx Shunt serves as the central monitoring point for your DC bus, measuring current flow and state of charge. A fuse failure here can lead to inaccurate readings or complete system shutdown. The Victron CNN fuse is manufactured to strict tolerances, ensuring consistent performance and a precise fit within the Lynx Shunt's fuse holder. This reduces the risk of poor contact, hot spots, and nuisance blowing that can occur with aftermarket alternatives.

For installers and system integrators, using the specified Victron fuse means compliance with the manufacturer's design parameters, preserving warranty coverage and simplifying fault diagnosis. The clear rating marking on the fuse body aids in quick identification during maintenance, while the central inspection window allows you to confirm fuse status without removal.

Applications

• Marine and RV electrical systems where space is limited and reliability is non-negotiable
• Off-grid solar installations using Victron MultiPlus or Quattro inverter/chargers
• Lithium battery banks requiring high interrupt ratings for safety
• Backup power systems in remote telecommunications or monitoring sites

Installation and Maintenance

Installing the Victron CNN 325A/80V fuse is straightforward: the forked terminals slide over the Lynx Shunt's busbar studs and are secured with nuts (not included). Always ensure the system is de-energised before servicing. While the fuse is designed for long service life, periodic inspection of the element through the window is recommended, especially after a known fault event. Keep a spare fuse on hand to minimise downtime during field replacements.
