Blue Sea Systems AGC Fast-Acting Glass Fuse, 32V DC, 25pk

Overview

The Blue Sea Systems AGC Glass Fuse is a fast-acting glass cartridge fuse for protected low-amperage circuits on boats, supplied here as a 25-pack in the selected amperage. AGC fuses are commonly used with Blue Sea Systems ST Glass fuse blocks and AGC or MDL fuse holders, and they are typically used in DC systems up to 32V DC.

This fuse style suits onboard electronics, small accessory circuits, and service spares where a clear glass body makes a blown fuse easier to spot during troubleshooting. AGC fuses up to 10A are rated for AC use at 125V AC and up to a maximum of 250V AC, while higher-amperage AGC options in this range are used for DC applications up to 32V DC.

Key features

• Fast-acting AGC glass fuse for small electronic devices and accessory circuits on marine electrical systems.
• Compatible with Blue Sea Systems ST Glass fuse blocks and AGC or MDL fuse holders.
• Typically used in DC systems up to 32V DC, covering common 12V and 24V boat installations.
• Visible blown condition helps speed up dockside or underway troubleshooting.
• Available in selected amperages from 1A through 30A, so fuse rating can be matched to the protected circuit.
• 25-pack format is useful for refits, service kits, and keeping spares aboard.

Variants

This AGC glass fuse range is offered in multiple amperage options: 1A, 2A, 3A, 5A, 7.5A, 10A, 15A, 20A, 25A, and 30A. The amperage is the key selection point, and it should match the rating required by the fuse holder, protected wire, and equipment manual.

Across the range, the product remains an AGC glass fuse supplied as a 25-pack. Lower ratings are commonly used for lighter electronics and control circuits, while higher ratings are used only where the circuit and holder are specified for that load.

Installation and fit

Install this fuse only in a compatible AGC or AGC/MDL fuse holder, with power disconnected before removal or replacement. The fuse should seat firmly in the clips or holder contacts; loose contact can create heat and intermittent faults, especially on boats where vibration is constant.

Fuse sizing should protect the wire first, then the equipment. When replacing a blown fuse, use the same amperage unless the circuit has been reviewed and corrected by a qualified marine technician.

Use cases on board

These fuses are practical spares for navigation electronics, small lighting circuits, pumps with suitable fuse requirements, instrument panels, and other protected accessory circuits that use AGC glass fuses. They are a good match for owners, installers, and service yards maintaining DC electrical panels that already use Blue Sea Systems ST Glass fuse blocks or AGC-compatible holders.
