Hamolar 80A Manual-Reset DC Circuit Breaker 3-Pack 12-48V for Car RV Marine - Includes Wire Lugs

Hamolar 3-pack 80 amp manual-reset DC circuit breakers protect 12–48V systems by interrupting overloads and allowing quick manual restart without swapping fuses.

These compact, user-resettable breakers are built for vehicle and marine 12V–48V electrical systems where repeated protection and convenient recovery are important. Each unit replaces an inline fuse holder and features a push-button reset that doubles as a quick shutoff. Supplied with wire lugs and copper washers, the set is sized for common audio amplifiers, trolling motors, RV systems, and other DC loads that need reliable overcurrent defense.

How does this breaker protect my amplifier or trolling motor?

The Hamolar 80A manual-reset device trips when current exceeds the rated threshold, stopping sustained overloads that can damage wiring, batteries, or connected electronics. Because it interrupts the circuit rather than melting like a fuse, it helps prevent thermal damage and unsafe battery conditions.

• Interrupts continuous overcurrent to prevent amplifier or motor damage
• Manual reset avoids repeated fuse replacements after transient events
• Rated for 12–48V DC to suit common automotive and marine systems
• Includes wire lugs and copper washers for secure terminal connections

What are the electrical and environmental specifications?

Each breaker is specified for DC operation across 12V through 48V systems, and carries an 80 amp trip rating suitable for mid- to high-current circuits. The units are designed to function across a wide temperature range, making them appropriate for both enclosed vehicle installations and exposed marine environments.

• Operating range: 12–48V DC compatible with 12V and 24V systems
• Trip rating: 80 amps for steady-state overcurrent protection
• Ambient temperature tolerance from cold starts to hot engine bays
• Supplied hardware: wire lugs and copper washers for reliable terminals

How do I install and reset these breakers in my vehicle or boat?

Installation replaces an inline fuse holder or installs at a convenient point between battery and accessory. Secure the wire lugs to the breaker posts with the included copper washers, torque to the vehicle manufacturer’s recommendations, and route wiring away from heat or abrasion. To restore power after a trip, simply press the top-mounted push button.

• Mount on a flat surface near the protected circuit using the supplied lugs
• Tighten terminals with copper washer to ensure low-resistance contact
• Use the push-button to manually reset after verifying the fault is cleared
• Can act as an accessible kill switch for rapid shutdown when needed

Why choose a manual reset breaker over a fuse?

Unlike single-use fuses, manual-reset breakers restore service with a button press, cutting maintenance costs and downtime for systems that experience occasional surges. They also provide clearer diagnostics: a tripped breaker signals an overload event without requiring fuse inspection or replacement.

• Reusable protection eliminates repeated fuse purchases and replacements
• Fast recovery after non-destructive trips—no spare fuse inventory needed
• Durable construction suited for automotive, marine, RV and off-grid setups

Who is this for? The Hamolar 3-pack of 80A manual-reset DC circuit breakers is made for installers, DIY vehicle and boat owners, and audio enthusiasts who need reliable, reusable overcurrent protection. It fits applications such as car audio amplifiers, trolling motors, RV electrical circuits, ATV winches, and marine sound systems where robust 12–48V protection and easy reset capability matter. Each kit includes wire lugs and copper washers to simplify mounting and ensure secure electrical contacts, helping you maintain safer, more dependable DC power installations.
