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

Hamolar 200 Amp manual-reset circuit breaker — a compact, reusable overload protector for 12–48V DC systems that safeguards amplifiers, trolling motors, and vehicle electrical circuits.

Whether you’re wiring a boat stereo, protecting a trolling motor, or adding a safeguard to an ATV winch, this triple-pack of Hamolar manual-reset breakers delivers high-current protection without the waste of one-time fuses. Each breaker is rated to interrupt up to 200 amps and is designed for environments from cold winters to hot engine bays. The unit includes practical installation extras — wire lugs and copper washers — so you have what you need to mount and secure the connections quickly.

How does this breaker keep my equipment safe?

The Hamolar breaker trips under excessive current to prevent wiring and connected devices from overheating or sustaining electrical damage. Instead of blowing a fuse, the push-button mechanism cuts power and can be reset once the fault is resolved, reducing downtime and consumable costs.

• Automatic interrupt at overloads, manual push-button reset
• Rated 200A for high-current circuits like amplifiers and winches
• Reusable protection lowers long-term replacement expense

Will it work with my boat, car, or RV electrical system?

Yes — the device is compatible with common 12V and 24V vehicle and marine systems and operates across a wider DC range up to 48V, making it suitable for many mobile power setups. It tolerates extreme ambient temperatures, so it’s stable in both cold storage and warm engine compartments.

• Operates from 12–48V DC, fits 12V/24V installations
• Temperature tolerance from roughly -32°C to 82°C (-25°F to 180°F)
• Supplied wire lugs and copper washers for reliable terminal connections

How easy is it to install and use?

Installation is straightforward: mount the breaker, attach the lugs to the power cable, and tighten the copper washers onto the stud terminals. After wiring, the red push button provides an obvious reset or convenient manual power cut if you need to disable the circuit quickly.

• Includes wire lugs and copper washers for immediate wiring
• Stud-style terminals accept common ring or lug terminals
• Push-button reset doubles as a simple kill switch for maintenance

What applications are best suited to this breaker?

This 200A manual-reset breaker is built for heavy-draw accessories and systems that may experience surges or short circuits. It’s especially practical where replacing fuses is inconvenient or when a reusable, visible reset control is preferred.

• Car and truck audio amps and alarm systems
• Marine gear such as trolling motors and onboard amplifiers
• ATVs, RVs, winches, and other high-current DC accessories

Who is this for: The Hamolar 3-pack fits DIY installers, marine enthusiasts, car-audio builders, RV owners, and small-fleet operators who want reliable, reusable overcurrent protection. If you need a high-amp, manual-reset solution that performs across harsh temperatures and includes the basic hardware for installation, this pack gives three identical breakers so you can protect multiple circuits or keep spares on hand.
