Blue Sea Systems AGC Fuse Kit, 41-Piece, 32V DC, Heavy Duty In-Line Fuse Holder

Overview

The Blue Sea Systems 5289 is a 41-piece AGC fuse kit for DC circuits up to 32V. It includes 40 AGC glass fuses in eight amperage ratings from 1A to 30A, plus a heavy-duty in-line AGC/MDL fuse holder, so you have a useful spread of common replacements in one pack.

This kit suits boats that use AGC or MDL glass fuses for smaller accessory and electronics circuits. It gives you four fuses each in 1A, 2A, 3A, 5A, 7.5A, 10A, 15A, and 30A, which helps when you are tracing a fault, replacing a blown fuse at the dock, or keeping spare protection on board for routine electrical work.

The AGC/MDL format works with ST Glass fuse blocks and AGC/MDL fuse holders. For a boat owner or technician trying to keep an older glass-fuse setup supported, this kit keeps the common ratings together with a matching in-line holder instead of piecing them together one by one.

Key features

• 41-piece kit with 40 AGC glass fuses and 1 heavy-duty in-line AGC/MDL fuse holder
• Eight common ratings included: 1A, 2A, 3A, 5A, 7.5A, 10A, 15A, and 30A
• Four fuses of each amperage, which is useful for spare stock and repeat replacements during troubleshooting
• 32V DC rating for low-voltage DC circuits used on many 12V and 24V boats
• AGC/MDL glass fuse format for systems that use ST Glass fuse blocks or AGC/MDL holders
• Glass-body fuse style makes the blown element easy to inspect during service checks
• Resealable pack keeps assorted fuse values together in one place

Compatibility and fit

This kit is for circuits that already use AGC or MDL glass tube fuses. It is not the right match for blade-style fuse panels or larger fuse types such as MIDI, ANL, or Class T, so it is worth checking the fuse holder or fuse block on the boat before ordering.

The included holder gives you an in-line option for repairs or small circuit additions where AGC or MDL protection is the correct format. That can be useful for accessory feeds, older electronics circuits, and other low-voltage runs that still rely on glass fuses.

Installation and use

When replacing a fuse, match the amperage to the circuit requirement and the existing protection scheme rather than moving to a higher value. If a fuse opens more than once, the problem is usually elsewhere in the circuit, so the load, wiring, and holder should be checked before another fuse goes in.

This assortment makes sense for owners who keep spare electrical consumables on board, as well as yards and technicians who service boats with AGC fuse blocks and holders. It is especially useful where a quick replacement can get a small circuit back online without hunting for individual fuse values.
