Victron MEGA-Fuse 250A 58V fuse

Product Description

The Victron MEGA-Fuse 250A 58V is designed to protect direct current circuits with high power levels in 48 V systems. Its MEGA-type construction with bolt-down mounting provides a large-surface, very low-resistance electrical connection, reducing losses and heating in main feeds. This fuse opens quickly in the event of short circuits or prolonged overcurrents, preserving the integrity of cables, terminals, inverters/chargers, MPPT controllers, and DC distributors. It is a robust and professional option for residential and commercial photovoltaic installations, as well as for marine, light industrial, and special vehicle applications.

Main Features

• 250 A rated current for very high demand lines.
• 58 V DC service voltage, optimal for 48 V battery banks.
• Standard MEGA-Fuse (bolt-down): secure connections, low voltage drop, and excellent thermal stability.
• Simple visual inspection and quick cartridge replacement in the DC panel.
• High mechanical resistance to vibrations and demanding environments.

Advantages or Benefits

• Selective protection in main feeds, preventing catastrophic damage to high-value equipment.
• Maximum efficiency due to its reduced internal resistance, key for high currents.
• Long-term reliability thanks to the bolted mounting that maintains torque.
• Minimal maintenance: front access, visual verification, and replacement in minutes.
• Native integration with Victron fuse holders and DC busbars for clean and organized panels.

Purpose or Applications

Suitable for protecting 48 V battery feeds to high-power inverters/chargers, outputs to high-capacity DC busbars or distributors, high-range MPPT solar controllers, and critical loads (pumps, compressors, DC-DC converters, light traction systems) in premium off-grid homes, small businesses, boats, and professional vehicles.
