Blue Sea Systems ATO/ATC Fuse Pack, 25pk, 32V DC, 1000A Interrupt Capacity

Overview

The Blue Sea Systems ATO/ATC Fuse Pack is a 25-pack of fast-acting blade fuses for low-voltage DC circuit protection on boats, vehicles, and other small-load electrical systems. Each fuse is rated for up to 32V DC and has a 1000A interrupt capacity, giving installers a straightforward replacement or service-stock option for ATO/ATC fuse panels and holders.

This range covers common branch-circuit sizes from 1A through 30A, so it is useful for marine electronics, lighting circuits, pumps, accessories, and other DC loads when the fuse amperage matches the equipment requirement and wiring size. The tin-plated connector blades help resist corrosion at the contact points, which matters in damp lockers, consoles, cabins, and other boat locations where moisture can shorten service life.

Key features

• 25 fuses per pack for stocking spares, refits, or repeated service work on DC panels.
• ATO/ATC blade format for use in compatible ATO/ATC fuse holders and fuse blocks.
• Fast-acting protection for electronics and other small loads that need quick response to overcurrent.
• 32V DC maximum voltage rating for common 12V and 24V DC installations.
• 1000A interrupt capacity for fault-current handling within the fuse rating.
• Tin-plated connector blades help limit corrosion at the fuse contacts in marine environments.
• Available amperage options include 1A, 2A, 3A, 5A, 7.5A, 10A, 15A, 20A, 25A, and 30A.

Variants

The range varies by amperage only, with each configuration supplied as an ATO/ATC fuse pack. The correct selection depends on the protected circuit, the equipment requirement, and the conductor size in the installation.

Across the listed amperages, the fuse style, 32V DC maximum voltage rating, 1000A interrupt capacity, tin-plated connector blades, and 25-pack format remain consistent.

Compatibility and fit

These fuses fit ATO/ATC blade-style fuse holders and fuse blocks, including Blue Sea Systems ST Blade, SafetyHub, ATO/ATC fuse holders, ST-Blade water-resistant fuse blocks, and WeatherDeck fuse panels that use this fuse format. Before replacing a fuse, match the amperage to the circuit protection requirement rather than simply copying a failed fuse that may have been installed incorrectly.

Installation and use on board

Install the fuse only with power removed from the circuit and with the fuse holder in good condition. A loose, heat-damaged, or corroded holder should be corrected before a new fuse is installed, since poor contact can create heat and nuisance failures even when the fuse rating is correct.

This pack is a practical fit for boat owners, marine electricians, and service teams that maintain DC distribution panels, electronics circuits, lighting, and accessory feeds. Keeping the right amperages on board can make troubleshooting faster during a weekend cruise, fishing trip, or dockside repair.
