Victron MEGA-Fuse 125A 58V Fuse

Product Description

The Victron MEGA-Fuse 125A 58V provides precise protection in direct current installations operating at high voltages, such as 48 V battery banks. Its MEGA standard (bolt-down cartridge) ensures a firm electrical contact with very low resistance, reducing losses and hot spots, and guaranteeing rapid opening in the event of severe faults. It is the appropriate solution to protect connections to 48 V inverters/chargers, DC distributors, high-power MPPT solar controllers, and lines supplying critical equipment in residential, commercial, and marine environments.

Main Features

• 125 A rated current for 48 V lines with significant demand and service continuity.
• 58 V DC operating voltage, compatible with 48 V systems and associated Victron electronics.
• MEGA-Fuse bolt-down format, with low voltage drop and excellent thermal stability.
• Direct visual inspection and quick cartridge replacement to minimize downtime.
• High mechanical robustness for applications with vibration or movement (marine, service vehicles, light industry).

Advantages or Benefits

• Enhanced safety at 48 V: limits fault energy before reaching inverters, BMS, or expensive wiring.
• Energy efficiency: its low-resistance construction helps maintain the overall performance of the installation.
• Long-term reliability: bolt-down mounting prevents loosening and improves contact stability.
• Simple maintenance: front access and replacement in minutes, with visual verification of the fuse status.

Purpose or Applications

Ideal for protecting the 48 V battery connection to inverters/chargers, outputs to distributors or power bars, inputs of high-range MPPT solar controllers, DC-DC converters, and critical loads in residential and commercial photovoltaic projects, vessels, and professional off-grid systems.
