Victron MIDI Fuse 80A/58V: Precision Circuit Protection for 48V DC Systems

Engineered for Reliable Overcurrent Protection in Demanding Environments

The Victron MIDI fuse 80A/58V delivers robust overcurrent protection for 48V DC electrical systems, safeguarding sensitive electronics and power distribution components from damage caused by short circuits or overloads. Designed to meet the rigorous demands of off-grid solar installations, marine electrical panels, and vehicle-based power systems, this fuse provides a critical layer of defence that helps prevent costly downtime and equipment failure.

Unlike generic automotive fuses that may struggle with sustained DC loads or exhibit inconsistent trip characteristics, the Victron MIDI fuse 80A/58V is purpose-built for low-voltage DC applications up to 58V. Its precise, time-current melting curve ensures predictable interruption of fault currents, reducing the risk of nuisance blowing while maintaining fast response to genuine overcurrent events. This reliability is essential in systems where battery banks, inverters, and charge controllers must operate continuously without interruption.

Low Voltage Drop for Maximum System Efficiency

Every millivolt lost across a fuse translates to wasted energy and reduced performance in a DC system. The Victron MIDI fuse 80A/58V features an exceptionally low voltage drop of 72 mV at rated current, minimising power dissipation and heat generation. This not only improves overall system efficiency but also reduces thermal stress on surrounding components, contributing to longer service life for your entire electrical installation.

The fuse's low cold resistance of 0.60 mΩ further enhances its performance, ensuring that it introduces minimal impedance into the circuit under normal operating conditions. This is particularly beneficial in solar charging systems where every watt of harvested energy counts, and in inverter circuits where voltage sag can impact appliance performance.

Compact, Standardised Form Factor for Easy Integration

With its industry-standard MIDI footprint, this fuse integrates seamlessly into Victron fuse holders and distribution blocks, as well as many third-party solutions. The compact dimensions allow for high-density mounting in electrical enclosures, making it ideal for space-constrained installations such as camper trailers, 4WD dual-battery setups, and marine switchboards.

Standardised M5 mounting holes (approx. 5 mm diameter) ensure secure, low-resistance connections when paired with appropriate ring terminals. The tin-plated copper terminals resist corrosion, maintaining reliable conductivity even in humid or salt-laden environments.

Built for the Real World

Victron MIDI fuses are engineered to withstand the vibration, temperature fluctuations, and humidity commonly encountered in mobile and off-grid applications. The robust construction and quality materials reduce the risk of premature failure that can plague lower-grade fuses, giving you confidence that your system remains protected when it matters most.

By choosing a Victron MIDI fuse 80A/58V, you mitigate the risk of catastrophic damage to expensive components such as inverters, battery management systems, and DC-DC converters. The precise protection characteristics help avoid the cascading failures that can occur when a fuse fails to clear a fault quickly and cleanly.

Ideal Applications

• Battery bank main circuit protection in off-grid solar systems
• Inverter DC input protection
• DC-DC converter and battery charger circuits
• Marine DC distribution panels
• 4WD and caravan auxiliary power systems

Protect your investment with the precision and reliability of Victron MIDI fuses. Whether you're building a new off-grid power system or maintaining an existing installation, these fuses provide the dependable overcurrent protection your equipment deserves.
