MEGA-fuse 400A/32V (package of 5 pcs). The Victron Energy MEGA-fuse is a type of high-current fuse specifically designed for DC systems. It is commonly used in systems such as:
- Battery Management Systems (BMS) – To protect batteries from overcurrent.
- Inverters and Chargers – To provide overcurrent protection for high-power equipment.
- Solar Power Systems – For protecting wiring and equipment in high-current DC solar setups.
Key Features
- Current Ratings: Available in a range of ratings, typically from 60A to 500A.
- Voltage Rating: Rated for up to 32V DC.
- Construction: Compact and durable with bolt-on terminals for secure connections.
- Application: Designed for use in automotive, marine, and renewable energy systems.
Installation
- The MEGA-fuse is typically installed in a fuse holder or on a busbar.
- Ensure the fuse rating matches the system’s maximum current requirements to avoid nuisance tripping or insufficient protection.
- Use proper tools to tighten the connections securely to prevent overheating.
Advantages
- High current-carrying capacity.
- Reliable and robust for demanding applications.
- Easy to replace when blown.
Applications in Solar or BMS
In a solar power system, the MEGA-fuse is commonly placed:
- Between the solar charge controller and the battery.
- Between the inverter and the battery.
- On the positive lead for load protection.
For a battery management system (BMS):
- It can serve as overcurrent protection for battery packs.
- It helps safeguard against short circuits.
