This 12-position breaker block is designed to deliver both power and ground distribution in a compact, durable layout. Supporting ATO or ATC style blade fuses, it protects up to 12 circuits—each rated for 30A, with a total block capacity of 100A.

The unit features a split bus design, allowing you to separate your circuits into two isolated groups, ideal for managing critical vs. non-critical systems or switched vs. constant power setups. This makes it a versatile choice for marine, RV, or off-grid installations where clean separation and reliable protection are essential.

Built from stainless steel, nickel-plated copper, and polycarbonate, it’s ready to withstand harsh environments. The block uses M5 threaded studs for main connections and M4 studs on the outputs, rated at 25A max per terminal. Mounting is easy with 0.1695” holes spaced at 4.85” high by 2.76” wide, ensuring a secure and tidy fit into most panels or compartments.

Whether you’re building from scratch or upgrading an old fuse box, this atc fuse block provides a clean, protected, and efficient wiring solution.
