Victron MEGA-Fuse 200A 58V fuse

Product Description

The Victron MEGA-Fuse 200A 58V is a professional protection element for direct current lines operating in 48 V battery banks. Its MEGA-type construction (bolt-down cartridge) ensures a firm and very low-resistance contact, reducing losses and hot spots, and providing fast and controlled opening in case of short circuit or sustained overcurrent. With a 200 A rating, it is especially suitable for main connections to high-power inverters/chargers, DC distributors, and high-capacity MPPT solar controllers in residential, commercial, marine, or mobile photovoltaic installations.

Main Features

• 200 A rated current for high-demand lines in 48 V systems.
• 58 V DC service voltage, suitable for 48 V battery banks.
• Standard MEGA-Fuse bolt-down: solid connections and low voltage drop.
• Direct visual inspection of cartridge status and quick replacement.
• High mechanical robustness against vibrations in marine, automotive, and light industry applications.

Advantages or Benefits

• Greater electrical safety by limiting fault energy before reaching critical equipment.
• System efficiency thanks to a very low internal resistance that minimizes heating.
• Prolonged reliability due to screw fixation, which prevents loosening over time.
• Agile and economical maintenance: front access and replacement in minutes.
• Compatibility with the Victron range of fuse holders, busbars, and DC distributors.

Purpose or Applications

Designed for 48 V battery connections to high-power inverters/chargers, outputs to distributors or power busbars in DC panels, protection of inputs/outputs of wide-range MPPT controllers, DC-DC converters, and critical loads (pumps, compressors, onboard electronics) in off-grid homes, businesses, boats, campers, and professional off-grid systems.
