Blue Sea Systems Marine Grade Short Stop Circuit Breakers, 2500A @ 28V DC, IP64 Boot, Push-to-Reset

Overview

The Blue Sea Systems Marine Grade Short Stop is a compact DC circuit breaker range for replacing fuses in low-voltage marine electrical circuits. It uses a thermal trip with manual reset, supports up to 28V DC, and has a 2,500A interrupt capacity at 28V DC, giving small branch circuits a resettable protection point without carrying spare fuses on board.

The breaker is made for exposed or semi-exposed boat wiring locations where spray, vibration, and corrosion are common concerns. An IP64 water-resistant boot helps protect against dust and splashing water, while stainless steel lock nuts help protect against dust and splashing water, while stainless steel lock nuts help keep terminal connections secure. The #10-32 terminal stud suits common marine ring-terminal installations when matched with the correct wire size, circuit load, and overcurrent protection plan.

Key features

• Thermal trip, manual-reset breaker that can be reset after a trip instead of replacing a blown fuse.
• Rated for DC systems up to 28V DC, suitable for many 12V and 24V boat electrical installations.
• 2,500A interrupt capacity at 28V DC for short-circuit protection within the breaker rating.
• IP64 boot helps protect the reset area from dust and splashing water in marine environments.
• Corrosion-resistant construction with stainless steel lock nuts for exposed boat wiring areas.
• #10-32 terminal stud supports ring-terminal connections, with 20 in-lb terminal torque specified for installation.
• Operating temperature range from -10°C to 60°C for common onboard electrical spaces.

Variants

This Short Stop breaker range varies by amperage, covering lower-load branch circuits through heavier DC loads. The amperage selection should match the protected wire size and the circuit requirements, not just the equipment draw, since the breaker’s main job is to protect the wiring.

The core construction and installation style stay consistent across the range, including the push-to-reset operation, 28V DC maximum voltage rating, #10-32 terminal stud, IP64 boot, and 2,500A interrupt capacity at 28V DC.

Installation and setup

Install the breaker as close as practical to the power source for the circuit it protects, following the boat’s wiring layout and applicable marine electrical practices. Use properly crimped ring terminals on clean conductors, tighten the terminal hardware to the specified torque, and protect the wiring from chafe, heat, fuel exposure, and standing water.

Because this is a manual-reset breaker, it works well in locations where quick access matters, such as battery-adjacent accessory feeds, small distribution runs, and individual DC equipment circuits. After a trip, the circuit should be checked for overloads, shorts, or damaged wiring before resetting the breaker.

Marine use

This range is a practical fit for boats that need resettable circuit protection without moving to a larger panel-mounted breaker. It suits small DC branch circuits in cockpits, consoles, helm wiring areas, equipment lockers, and other locations where a compact breaker can be mounted near the protected circuit.

Quality Boat Parts is a reseller. Many items include a manufacturer’s warranty, and all warranty service is handled directly by the manufacturer. We do not manage or administer warranty claims on behalf of customers.

Warranty terms, coverage, and duration are set by each manufacturer. Issues involving defects, repairs, or replacements must be addressed with the manufacturer’s support team. When available, the warranty period is listed on the product page. If it is not shown, contact us or the manufacturer for details before purchasing.

To start a claim, the customer must contact the manufacturer and follow their process. Keep your proof of purchase and original packaging, and register the product if the manufacturer requires it, as these are often needed for warranty service.
