Hamolar 200A Manual-Reset Circuit Breaker 3-Pack for 12–48V Systems — Copper Washers & Wire Lugs, Resettable Overload Protection

Hamolar 200A manual-reset circuit breakers are compact, reusable overload protectors for 12–48V DC systems that safeguard amplifiers, trolling motors and vehicle electronics by interrupting excessive current and allowing a quick manual restart.

Designed for automotive, marine and powersports use, this 3-pack of Hamolar circuit breakers replaces inline fuse holders with a push-button reset that doubles as a kill switch. Each breaker is rated for 200 amps and compatible across 12V and 24V systems, fitting installations in cars, boats, ATVs, RVs and more. Built to withstand wide temperature ranges and supplied with copper washers and wire lugs, these breakers simplify wiring while reducing the need for disposable fuses.

How does the Hamolar breaker protect my audio or motor system?

When current exceeds safe levels, the internal trip mechanism opens the circuit to stop sustained overcurrent that can harm amplifiers, motors or batteries. The manual-reset button clears the fault and restores power once the underlying issue is resolved.

• 200A trip threshold interrupts harmful surges and prolonged overloads
• Manual reset avoids fuse replacement after a single event
• Can act as a quick-access kill switch for emergency shutdown

Will these breakers work with my 12V or 24V system?

Yes — the Hamolar units are specified for 12–48V DC, making them compatible with common 12V and 24V vehicle and marine electrical setups. They’re suitable for audio systems, trolling motors and winches that operate within that voltage range.

• Rated voltage range: 12–48V DC for flexible use
• Fits 12V car batteries, 24V marine/industrial banks and intermediate voltages
• Supplied wire lugs and copper washers for secure terminal connections

How do I install and reset the breaker safely?

Mount the breaker to a solid surface, secure battery and load cables with the included copper washers and wire lugs, and torque connections to manufacturer recommendations. If the breaker trips, locate and fix the cause of the overload before pressing the center button to reset.

• Disconnect power and tidy wiring before mounting
• Use supplied lugs and washers for proper contact and corrosion resistance
• Reset only after remedying short circuits or excessive loads

What environments and temperatures can these handle?

Hamolar circuit breakers are built to perform across a broad ambient range, suitable for vehicles and marine settings where temperatures and operating conditions vary. Their durable construction helps resist common workshop and outdoor stresses.

• Operating ambient temperature from −32°C to 82°C (−25°F to 180°F)
• Robust housing for vehicle, boat and ATV environments
• Corrosion-resistant copper washers improve long-term terminal reliability

Who is this for: Technicians, DIY installers and vehicle owners who need a reliable, reusable overload protection solution for 12–48V electrical systems. Ideal for car audio enthusiasts, boat owners fitting trolling motors, RVers and ATV operators who prefer a resettable breaker over disposable fuses. The 3-pack gives spare units for multiple circuits or backup replacements, and the included hardware simplifies a clean, safe installation.
