Product Overview
MEGA fuses are a widely used format in automotive, marine and off-grid solar DC systems. The blade-style body fits into a dedicated MEGA fuseholder and provides a clear, serviceable point of overcurrent protection on the main positive cable between the battery and the load or inverter. At 500A, this fuse is rated for the highest-draw DC equipment, including large Victron Quattro and MultiPlus inverter/chargers where cable protection at the battery terminals is required.
The 80V DC rating gives adequate headroom above nominal 48V battery voltages, including lithium systems that may reach 58V or above at full charge. This makes the fuse suitable across the full range of common battery chemistries and voltages used in off-grid, marine and vehicle installations. Using the correct fuse rating for the cable cross-section and connected equipment is essential: a 500A fuse should only be used where the cable and terminals are rated to carry that current continuously.

Installation Notes
MEGA fuses must be installed in a compatible MEGA fuseholder rated for the current and voltage of the application. Ensure the fuseholder, cable lugs and cable cross-section are all rated to carry 500A continuously before fitting this fuse. DC systems at these current levels carry significant energy and can cause fire or serious injury if incorrectly wired. Installation should be carried out by a qualified electrician or experienced system integrator familiar with DC battery systems. For grid-connected solar installations, work must comply with current UK wiring regulations and be carried out by a suitably qualified installer.
