Overview

The Blue Sea Systems 5060 is a crimpable in-line fuse holder for AGC and MDL glass fuses in DC circuits on board. It accepts 12 to 18 AWG wire and supports fuse ratings up to 30A, with the fuse selected separately to match the circuit you are protecting.

This type of holder is used when you want fuse protection in the wire run for one accessory or branch circuit instead of at a larger fuse block. It suits 12V and 24V systems that use AGC or MDL fuses and is a straightforward fit for lighting, electronics leads, instrument feeds, and other circuits wired in the 12 to 18 AWG range.

Key features

• Crimpable in-line holder for AGC and MDL glass fuses
• Accepts 12 to 18 AWG wire for smaller DC branch circuits
• Supports fuse amperage up to 30A
• Fuse is sold separately, so the circuit can be protected with the correct amperage for the wire and load
• In-line format lets circuit protection be placed where it makes the most sense in the wiring run

Compatibility and fit

Check that your circuit uses 12 to 18 AWG cable and that the chosen AGC or MDL fuse does not exceed 30A. This holder is a practical option when the rest of the system already uses glass fuses and you need a simple in-line replacement or a new fused lead for one device.

Installation and setup

The in-line crimp format works well when the holder is installed close to the power source or near the start of a branch lead so the protected section of wire stays short. On a boat, that usually means using proper marine crimping practice, securing the wire so vibration does not pull on the holder, and choosing a fuse value that matches both the connected load and the wire size.

Use on board

This product is a good fit for boat owners and installers adding a single fused circuit without moving to a multi-circuit fuse block. It also makes sense as a service replacement where an existing AGC or MDL in-line holder has become worn and the rest of the wiring layout is still suitable.
