This 12 circuit ATC - style breaker block is built for larger systems that require clean, resettable circuit protection without the hassle of fuses. It supports up to 12 circuits, each rated for 30A, with a total input capacity of 100A, making it ideal for boats, RVs, off-grid power setups and custom vehicles.

Designed to accept standard ATO or ATC resettable breakers, this panel uses M6 threaded studs for the main power input and M4 studs for the outputs, ensuring reliable, corrosion-resistant connections. Constructed from stainless steel, nickel-plated copper, and polycarbonate, it’s engineered to handle tough environments while keeping your wiring safe and organized.
