Hamolar 200A Manual Reset Circuit Breakers 3-Pack for 12V–48V DC — Wire Lugs & Copper Washers

Hamolar 3 Pack 200 Amp manual-reset circuit breakers offer reusable overcurrent protection for 12V–48V DC systems in cars, boats, ATVs and audio setups. Built for mobile and marine power systems, this three-piece set of 200A manual-reset breakers replaces inline fuse holders while giving a visible push-button reset and the option to act as a kill switch. Each breaker includes wire lugs and copper washers so you can install them directly into battery or distribution circuits for trolling motors, amplifiers, winches and other heavy-draw equipment. The units are rated for a broad temperature range and compatible with standard 12V/24V systems that operate up to 48V DC.

How do these breakers protect my amplifier and battery?

These manual-reset breakers interrupt excessive current before wiring or components overheat. When an overload or short occurs, the breaker trips and disconnects the circuit, preventing damage to amps, batteries and connected devices.

• 200A trip rating for high-current circuits
• Reusable push-button reset avoids fuse replacement
• Prevents overheating and wiring damage from sustained overcurrent
• Includes copper washers and wire lugs for secure connections

Can I use these on boats, trolling motors and other marine gear?

Yes—these breakers are suitable for marine environments when installed correctly. They protect trolling motors, marine amplifiers and other DC loads by stopping dangerous current spikes and allowing quick manual reset once faults are cleared.

• Rated for 12V–48V DC systems common in marine setups
• Wide ambient temperature tolerance from −32°C to 82°C
• Manual reset also doubles as an accessible kill switch
• Corrosion-resistant copper washers included for reliable terminals

How do I install these on my vehicle or RV?

Installation is straightforward for anyone comfortable with basic DC wiring: mount the breaker to a secure surface, attach the supplied wire lugs with the copper washers, and torque the terminals to spec. Always disconnect the battery before wiring and follow recommended wire gauge for 200A circuits to maintain safety.

• Mount using the threaded stud and secure nut provided
• Use appropriately sized cable and proper crimped lugs
• Disconnect battery power before beginning installation
• Confirm torque and inspect connections for corrosion or looseness

What limits and operating conditions should I watch for?

These breakers are designed for DC systems up to 48 volts and ambient temperatures between −32°C and 82°C. They protect against overloads but are not intended as a substitute for circuit designs that exceed the 200A rating or for continuous loads above rated capacity.

• 200A maximum current rating per breaker
• Operates in −32°C to 82°C (−25°F to 180°F) environments
• Compatible with 12V and 24V systems; safe up to 48V DC
• Manual reset must be used only after diagnosing the fault

This Hamolar 3-pack is ideal for DIY installers, boat owners, audio enthusiasts, and off-road vehicle operators who need durable, resettable overcurrent protection without frequent fuse replacement. If you want a reusable, visible protection device that also serves as a manual kill switch and arrives with installation hardware, this set simplifies wiring upgrades for amplifiers, trolling motors, winches and other high-current DC loads.

FAQ

Q: Are these breakers reusable after tripping?

A: Yes. The Hamolar 200A breakers reset with the push button, so you don't need to replace fuses after a trip.

Q: Do these work on 24V and 48V systems?

A: Yes. They are compatible with 12V and 24V systems and safe for use in DC systems up to 48V.
