The Victron MIDI-fuse 50A/58V with M6 bolt connection is a blade-style fuse rated for 58V DC systems, supplied in a pack of five. It suits DC protection circuits on solar, battery and inverter installations where a compact, reliable fuse is needed.

Key features

• Current rating, 50A, suitable for DC circuit protection in battery and solar systems.
• Voltage rating, 58V, covering typical 12V, 24V and 48V DC system voltages.
• Terminal, M6 bolt connection for a secure, low-resistance contact.
• Format, MIDI blade fuse, compatible with standard MIDI fuseholders.
• Pack quantity, supplied as 5 pieces, useful as spares for commissioning and maintenance.
• Weight, 0.015 kg per pack.

Applications

MIDI fuses are a common choice for DC overcurrent protection in off-grid and battery-based systems. The 50A rating suits cable and equipment protection on 12V, 24V or 48V battery banks, inverter inputs, and DC distribution circuits. The M6 bolt terminal gives a firm mechanical connection that resists vibration and thermal cycling, relevant to marine, mobile and fixed off-grid installations. The 58V rating covers fully charged 48V lithium and lead-acid battery systems.

Typical uses

• DC overcurrent protection on 12V, 24V and 48V battery systems.
• Inverter input cable protection in off-grid and hybrid solar installations.
• DC distribution boards and busbar protection in marine and motorhome builds.
• Battery-to-charge-controller wiring protection in solar PV systems.
• Replacement fuses for existing MIDI fuseholder installations.

What's in the box

• 5 x Victron MIDI-fuse 50A/58V M6

Installation notes

Fit these fuses only in a compatible MIDI fuseholder rated for the same voltage and current. Torque the M6 bolt terminals to the fuseholder manufacturer's specification to avoid loose connections. Size DC fusing to protect the cable, not just the load. Isolate the battery before replacing fuses, and use a qualified installer for battery and inverter work.
