• Voltage rating, 80V DC, covering 12V, 24V and 48V battery systems.
• Format, standard MEGA-fuse blade body, fits standard MEGA fuseholders.
• Pack size, 5 fuses, useful for stocking spares or multi-installation jobs.
• Part number, Victron Energy CIP138175020.
• Weight, 45g per pack.

Product overview

MEGA-fuses are used to protect main battery cables in inverter, charger and battery management installations. A 175A rating sits between the more common 150A and 200A options, useful where cable sizing or equipment ratings need a tighter protection threshold. The 80V DC rating gives margin over standard lead-acid and lithium voltages up to 48V nominal.

Fit the fuse in a MEGA fuseholder that accepts the standard blade body and secures it with bolt terminals. Fuse selection should be based on cable cross-section, ambient temperature and the continuous current draw of the connected equipment: the fuse protects the cable, not just the load.

Applications

• Main battery cable protection in off-grid solar installations with Victron inverters or inverter/chargers.
• DC circuit protection in marine electrical systems.
• Vehicle and motorhome leisure battery installations.
• Battery bank protection in 12V, 24V and 48V energy storage systems.
• Replacement fusing for existing MEGA fuseholder installations.

What's in the box

Installation notes

Fit MEGA-fuses in a compatible fuseholder rated for the application voltage and current, positioned as close to the battery positive terminal as practicable. DC work on battery systems, especially those above 48V or with high short-circuit current, should be carried out by a qualified electrician or accredited installer. Check the fuse rating suits the cable cross-section before fitting.
