Victron Energy MIDI-Fuse, For 48V Products, 58V, 1pc

Overview

The Victron Energy MIDI-fuse 58V for 48V products is a bolt-down DC fuse range for protecting 48V boat electrical circuits against overcurrent. It uses the MIDI fuse format, with current ratings from 30A to 100A and a 58V DC rating that matches higher-voltage DC systems found on modern marine power installations.

This range suits protected battery feeds, DC distribution runs, and Victron 48V equipment installations where the fuse must match both the circuit voltage and the cable or equipment current limit. Across the listed ratings, the approximate voltage drop is 65 mV to 70 mV, which helps keep losses predictable in compact DC panels and battery compartments.

Key features

• 58V DC rating for use with 48V products and higher-voltage DC boat systems within the fuse rating.
• MIDI fuse format with a bolt-down connection for secure mounting in a compatible MIDI fuse holder.
• Available current ratings cover 30A, 40A, 50A, 60A, 80A, and 100A circuit protection needs.
• Approximate voltage drop is specified at 65 mV for the 30A, 40A, and 50A versions, and 70 mV for the 60A, 80A, and 100A versions.
• Cold resistance values are specified by rating, helping system builders account for losses in DC power layouts.
• Small MIDI footprint helps when adding protection inside battery boxes, distribution panels, and equipment spaces where room is limited.

Variants

The range varies by current rating: 30A, 40A, 50A, 60A, 80A, and 100A. Each option uses the same MIDI fuse style and 58V DC voltage class, with the current rating selected to match the protected cable, load, and upstream power source.

The lower-current versions are commonly used on lighter DC branches or smaller 48V loads, while the higher-current versions suit heavier battery and distribution circuits when the wiring and connected equipment are sized for that current. Final fuse selection should follow the equipment requirements and the boat’s DC cable sizing.

Installation and fit

Install this fuse in a compatible MIDI fuse holder, close to the power source where practical, so the downstream cable is protected from the start of the run. On boats, that usually means planning the fuse location around battery access, service clearance, ventilation, and protection from accidental contact with live conductors.

Use clean, tight connections and hardware that suits the fuse holder. In saltwater environments, keep the fuse area dry where possible and inspect terminals during routine electrical checks, especially in battery compartments and other spaces exposed to vibration or moisture.

Electrical selection

The current rating should not be chosen only by the connected device’s normal running current. It also needs to match the cable size, cable length, expected load behavior, and any installation limits stated for the equipment being protected. For inverter, charger, DC-DC, and distribution circuits, the fuse is part of the complete protection plan rather than a standalone fix.

This product is a good match for boat owners and installers building or servicing Victron-based 48V DC systems who need a compact MIDI fuse with a verified 58V DC rating and clearly separated amp choices.

What’s included

• One MIDI-fuse in the selected current rating.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
