Leave your feedback

MEGA-fuse 250A/80V — this is an industrial high-current fuse from Victron Energy, created for the uncompromising protection of direct current (DC) circuits. It provides reliable contact interruption in case of abnormal overloads and short circuits in systems with a current up to 250 Amperes. A huge voltage reserve up to 80 V allows you to safely use it in 12, 24, and 48-volt systems.

An optimal choice for connecting flagship inverters, massive battery assemblies, and global DC busbars, where reaction speed and ultra-low resistance are critically important.

Advantages and Specifications of MEGA-fuse 250A

Operating current: 250 A, voltage support — up to 80 VDC
Internal resistance of only 0.20 mOhm — no loss of efficiency and overheating
Voltage drop of no more than 110 mV — perfect balance of conductivity
Instant circuit opening on short circuit
Popular MEGA standard size — compatible with all holders of this standard
Convenient and fast installation
Full certification by Victron Energy — guaranteed reliability in any scenarios

Design Features

Special fusible element — physically burns when the critical current limit is reached, 100% blocking the development of fire hazardous situations
Ultra-low cold resistance (0.20 mOhm) — easily withstands sharp starting currents of heavy equipment
Multi-level selectivity — simplifies protection calculation in complex tree-like electrical networks.

Where It Is Applied

Protection of main battery blocks (12 V, 24 V, 48 V)
Installation of heavy Victron Energy inverters (Quattro, powerful MultiPlus)
Safety of thick power cables and distribution platforms
Equipment of commercial water transport — where reliability is paramount
Expedition motorhomes with energy-intensive consumers (air conditioners, heaters)

Additional Equipment

MEGA Fuse Holder — insulated holder for safe installation
DC Distribution 250 — distribution panel with busbar and mounting slots
BatteryProtect — device to protect the battery from voltage drops
Victron Smart Battery Shunt — advanced battery condition monitor

Is this fuse suitable for installation in 12-volt systems?

– Absolutely, this protection element is compatible with any DC network with a voltage of up to 80 V.

What is the main difference between MEGA and MIDI fuses?

– The MEGA form factor has larger dimensions and is capable of withstanding significantly higher currents (up to 500 A).

Is it permitted to install it in inverter units?

– Yes, this is a recommended solution for the reliable protection of MultiPlus, Quattro series equipment and similar devices.

Which holder should be used for the MEGA fusible link?

– It is best to use the original MEGA Fuse Holder manufactured by Victron or high-quality certified analogues.

Is an instantaneous blowout guaranteed in the event of a short circuit?

– Yes, however, the exact melting speed of the filament directly depends on how many times the actual current exceeds the nominal rating.

At what temperature does this fuse trigger?

– The primary trigger factor is the strength of the flowing current, not the ambient temperature. But external overheating can accelerate the melting process.

Is external mounting of the fuse allowed outdoors?

– This is only possible if the holder used has an IP65 or higher dust and moisture protection class.

Is it suitable for use in automotive electronics?

– Yes, this model is fully certified for operation on various types of transport.

What is the maximum voltage for safe operation?

– A maximum of 80 V direct current (DC).

Will the link blow from short-term surge currents?

– No, the fuse is designed to withstand short-term peaks. This should be taken into account when calculating the system.

Is it strictly mandatory to buy a MEGA Fuse only from the Victron brand?

– No, it is not mandatory, but original Victron elements are guaranteed to meet the declared high-quality standards.

How to correctly calculate the required rating?

– Follow the instructions for your equipment! Usually, the rating is calculated as the peak current of the device plus a safety margin of 25–30%. If in doubt, consult a qualified specialist.
