xMEGA-Fuse 125A/58V for 48V Systems — CIP137125010
The Victron MEGA-Fuse 125A/58V is a high-current blade-style fuse designed for overcurrent protection in 48V battery and DC systems. It is suited to professional solar, off-grid and battery installations where reliable, rated protection of DC cabling and equipment is required. Sold as a single unit.
Key Features
- Rated at 125A continuous current with a maximum voltage rating of 58V DC, making it compatible with 48V nominal battery systems.
- MEGA-fuse format: a widely used, bolt-down blade fuse standard designed for high-current DC applications.
- Provides overcurrent protection for DC cables, busbars and equipment in battery-based systems.
- Compact and lightweight at 9g, suitable for installation in tight enclosures and battery compartments.
- Single-piece supply (CIP137125010). If stock is zero, the equivalent twin-pack alternative is CIP138125020.
- Compatible with standard MEGA fuseholders used across Victron and third-party DC distribution assemblies.
Product Overview
MEGA-fuses are a bolt-down, high-current fuse format commonly used in DC battery systems, inverter installations and solar charge controller wiring. The 125A rating makes this fuse appropriate for protecting cables and equipment on 48V battery banks, where fault currents can be substantial. The 58V maximum voltage rating provides adequate headroom above the typical fully-charged voltage of a 48V lithium or lead-acid battery bank.
In a correctly designed system, the fuse should be installed as close as possible to the positive terminal of the battery, in line with the main DC feed. This limits the length of unprotected cable in the event of a short circuit. The MEGA format requires a compatible fuseholder; this listing covers the fuse element only.

Installation Notes
This fuse must be installed in a compatible MEGA fuseholder rated for the application voltage and current. Always install the fuse as close as practicable to the battery positive terminal to minimise unprotected cable length. DC battery systems at 48V can deliver very high fault currents; installation should be carried out by a qualified electrician or accredited installer familiar with DC battery system wiring. Do not exceed the 58V DC voltage rating of this fuse.
