Description
xMEGA-Fuse 100A/80V (Pack of 5)
The Victron Energy MEGA-fuse 100A/80V is a high-current blade fuse designed for DC circuit protection in battery systems, inverters and other high-current 12V, 24V and 48V applications. Supplied in a pack of five, it is suited to installers and system builders who need reliable overcurrent protection on DC busbars and cable runs.
Key Features
- 100A continuous current rating for high-current DC protection.
- 80V DC voltage rating, compatible with 12V, 24V and 48V battery systems.
- MEGA blade fuse format, compatible with standard MEGA fuseholders.
- Supplied as a pack of 5, reducing per-unit cost for multi-circuit or multi-system installations.
- Compact and lightweight at 45g per pack, easy to carry as service stock.
- SKU CIP138100020, GTIN 8719076061663 for straightforward ordering and inventory management.
Product Overview
MEGA-fuses are a widely used format in DC electrical systems, particularly where high continuous currents must be protected at relatively low voltages. The 80V DC rating covers the full range of common battery bank voltages, including 48V nominal systems which can reach higher voltages during charging. At 100A, this fuse is appropriate for protecting main battery cables, inverter feeds and DC distribution connections where the circuit design calls for that current threshold.
The MEGA format uses a bolted or clamped fuseholder rather than a push-in blade, which provides a more secure connection under vibration and thermal cycling. This makes it a practical choice for marine, vehicle and off-grid installations where connections are subject to movement. Victron Energy produces these fuses to complement their range of MEGA fuseholders, ensuring dimensional and electrical compatibility across their DC protection product line.

Installation Notes
MEGA-fuses must be installed in a compatible MEGA fuseholder rated for the intended current and voltage. Ensure the fuseholder and all associated cabling are correctly rated for 100A continuous DC current before installation. DC electrical work on battery systems carries risk of arc flash and short-circuit injury. Installation should be carried out by a qualified electrician or competent person familiar with DC system design. For systems connected to a solar PV array or grid-tied inverter, ensure all relevant UK wiring regulations and G98/G99 requirements are observed by a suitably qualified installer.
