Victron Energy MEGA-fuse 250A/58V for 48V products

MEGA-fuse 250A/58V — is a high-current fuse designed to protect DC systems in Victron Energy power solutions. It provides reliable circuit protection against overloads and short circuits in systems up to 250 amps at a rated voltage of up to 58 V (12, 24, or 48 V).

Ideal for protecting inverters, chargers, battery cables, and DC busbars where a fast response to current anomalies and minimal resistance are critical.

Key advantages of the MEGA-fuse

• Rated current: 250 A, voltage — up to 58 VDC
• Low internal resistance: 0.2 mΩ — minimal energy loss
• Voltage drop: 80 mV — optimal electrical efficiency
• High response speed during a short circuit
• Standardized MEGA format — compatible with popular holders
• Compact size, easy installation
• Certified by Victron Energy — works perfectly in combination with other equipment from the brand

Technical Features

• Fuse type — trips when the current exceeds the rated value, preventing damage to cables, batteries, and electronics
• Low cold resistance (0.2 mΩ) — suitable for applications with high inrush currents
• Provides selectivity — in multi-level systems, allows for proper calculation of cascade protection

Application scenarios

• Protection of battery banks in 12/24/48 V systems
• Protection of Victron Energy inverters (MultiPlus, Quattro)
• Protection of cables and DC busbars
• Marine systems — where compactness and reliability are critical
• Motorhomes and campers — protection for high-current loads
