The Victron Energy MEGA-fuse 125A/80V is a high-current blade-style fuse used to protect DC battery systems, inverters and solar installations from overcurrent faults. This listing is for a pack of five, model CIP138125020, sized for installers fitting protection across several circuits at once.

MEGA fuse features and rating

• Current rating, 125A continuous, with an 80V DC voltage rating suited to 12V, 24V and 48V battery systems.
• Format, MEGA-fuse blade type, a compact high-current standard used in automotive and marine DC wiring.
• Pack quantity, 5 fuses, weighing 45g per pack.
• Compatibility, fits standard MEGA fuseholders, including Victron's own CIP range.

Applications

Fitted between battery banks and inverters or inverter/chargers, in DC distribution boards and busbars, and in motorhome, caravan and commercial vehicle builds. Also used for multi-circuit protection in off-grid solar systems with high battery discharge currents, and as replacement fusing in existing MEGA fuseholder installations.

Fuse selection and installation

A fuse should be rated to protect the cable, not the load, so the 125A rating needs pairing with cable capable of carrying that current continuously. Fit it as close to the battery positive terminal as practically possible to keep unprotected cable length to a minimum. DC work on battery systems, particularly where inverters or lithium banks are involved, should be carried out by a qualified electrician or accredited installer, and cable cross-section should always be checked against the fuse rating before fitting.
