DC Circuit Breakers (Marine Rated)

Manual Reset Circuit Breaker (100A / 200A / 300A) A serious upgrade over the typical low-cost breakers. These heavy-duty manual reset circuit breakers are built for reliable high-current protection in demanding 12V and 24V DC systems. Each unit uses robust internal components and proper contact pressure to deliver consistent performance — without the nuisance tripping and premature wear commonly seen in cheaper alternatives. It's quality you can actually feel. Built for Real-World Use An increased pressure, heavy-duty internal spring, ensures firm contact engagement, reduced arcing, and long service life — especially under sustained high loads. Why You’ll Love It Selectable ratings: 100A / 200A / 300A (choose your variant) Nickel-plated brass studs (M8 / 5⁄16") for excellent conductivity Stainless steel nuts & lock washers for corrosion resistance Manual reset lever — simple, reliable operation Line & Load clearly marked for quick installation Waterproof construction suitable for marine environments Ignition protected — safe for enclosed or engine bay installs Heavy-duty internal design for long-term durability Built Better Than Budget Breakers Not all breakers are created equal. Many low-cost units use undersized internals, weak contact pressure, and poor-conductivity hardware — leading to heat buildup, voltage drop, and early failure. These breakers combine high-conductivity brass studs with corrosion-resistant stainless hardware, giving you dependable protection and long-term performance where it matters most. Installation Tip Install as close as possible to the power source (battery or busbar) to properly protect downstream wiring and equipment.
