Description
xMEGA-Fuse 250A/80V — CIP138250020 (Pack of 5)
The Victron Energy MEGA-fuse 250A/80V is a high-current blade-style fuse rated for use in 12V, 24V and 48V DC battery systems. Sold in a pack of five, it is suited to professional installers who need reliable overcurrent protection on high-current DC circuits such as inverter feeds, battery interconnects and busbar connections.
Key Features
- 250A continuous current rating provides overcurrent protection on heavy-duty DC circuits.
- 80V DC voltage rating makes it compatible with 12V, 24V and 48V battery systems.
- MEGA blade-fuse format fits standard MEGA fuseholders, including Victron's own range.
- Pack of 5 fuses, practical for installers carrying spares or completing multi-circuit installations.
- Compact, low-profile body keeps installation neat within battery enclosures and distribution boards.
- Weight of 45g per pack confirms a lightweight, space-efficient form factor.
Product Overview
MEGA fuses are a widely used format in DC power systems, particularly where high current flows between batteries and inverters or charge controllers. The 250A rating is a common choice for inverter installations in the 2kW to 5kW range on 12V or 24V systems, where cable runs from the battery bank require protection against short-circuit faults. At 80V DC, the fuse is rated well above the maximum operating voltage of a 48V battery system, providing an appropriate safety margin.
The MEGA format uses a bolt-down or clip-in fuseholder rather than a plug-in blade, which makes it more suitable for high-current applications than standard automotive blade fuses. This fuse is designed to be used with a compatible MEGA fuseholder. The fuseholder is sold separately. Always verify that the fuseholder is rated to match or exceed the fuse's current and voltage ratings before installation.

Installation Notes
MEGA fuses must be installed in a compatible MEGA fuseholder rated for the circuit voltage and current. Fuses should be positioned as close to the positive battery terminal as practicable to protect the full length of the cable run. DC wiring at these current levels carries significant fault energy, and all connections should be made by a qualified electrician or competent installer familiar with DC battery systems. Ensure cable cross-section is correctly sized for 250A continuous current before selecting this fuse rating.
