MEGA-fuse 400A/32V — is a high-current fuse designed to protect direct current (DC) systems in Victron Energy electrical solutions. It provides reliable circuit protection against overloads and short circuits in systems up to 400 amps at a rated voltage up to 32 V (12 or 24 V).
Ideal for protecting inverters, chargers, battery cables, and DC busbars, where fast response to current anomalies and minimal resistance are critical.
Key advantages of the MEGA-fuse
- Rated current: 400 A, voltage — up to 32 VDC
- Low internal resistance: 0.13 mΩ — minimal energy loss
- Voltage drop: 70 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 (0.13 mΩ) — suitable for applications with high inrush currents
- Provides selectivity — in multi-level systems, it allows for the correct calculation of cascaded protection
Application scenarios
- Protection of battery banks in 12/24 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
