Overview

The Victron Energy CIP134050020 is a MIDI-fuse rated at 50A and 58V DC with M6 connections, supplied as a package of five. It is a compact over-current protection part for DC distribution on boats, especially where battery chargers, DC-DC chargers, solar charge controllers, inverters, or branch circuits need a serviceable fuse in a compatible MIDI holder.

For the 50A/58V MIDI rating, the fuse has an approximate voltage drop of 65 mV and a cold resistance of 1 mO. Those values matter in low-voltage marine systems, where every connection and protection device adds some resistance and heat under load.

Key features

• 50A current rating for protecting DC circuits that have been sized and fused around that load.
• 58V DC rating for low-voltage marine electrical systems where the circuit voltage stays within the fuse rating.
• MIDI format gives a smaller footprint than MEGA fuses in compact battery and distribution panels.
• M6 connection format matches fuse holders and studs specified for M6 MIDI fuses.
• Approximate 65 mV voltage drop and 1 mO cold resistance help keep losses predictable in protected DC runs.
• Five fuses in one pack gives installers spares for commissioning, service, and future circuit changes.

Compatibility and fit

Use this fuse only with a compatible MIDI fuse holder that accepts M6 connection hardware. It is not a replacement for ANL or MEGA fuse formats, and the holder, cable size, terminal hardware, and fuse rating should all match the circuit design.

The 50A rating makes it suitable for DC circuits that call for this specific fuse size rather than a higher-current main battery fuse. The fuse is a one-time protection device, so a blown fuse should be replaced after the fault has been found and corrected.

Installation and service

In a boat installation, place the fuse holder in an accessible DC distribution area where it is protected from spray, bilge moisture, and accidental contact with tools or loose gear. Clean, tight terminals are important on any marine DC circuit, especially around batteries and charging equipment where vibration and current load can expose weak connections.

This pack is useful for refits, spare parts kits, and service work on Victron-based electrical systems. It suits boat owners and installers who want matching replacement fuses on board instead of mixing fuse formats during maintenance.
