300A Max Marine Rated Battery Fuse MRBF Terminal Block Combo Pack Ignition Protected

Marine-grade, ignition-protected fuse blocks accommodate high amperage MRBF fuses. Suitable for protecting DC main, inverter, windlass, and bow thruster circuits. Mounts on a 3/8" battery post, battery switch or busbar, allowing for easy installation in tight space constraints and satisfies circuit protection rule. Includes insulating cap to prevent accidental shorts. Surface mount fuse blocks accommodate 1 MRBF fuses, for consolidated high amperage circuit protection. Utilizes marine-grade stainless steel and UV-stabilized plastics, and are ignition protected. Clip-on cover insulates terminal connections and includes label recesses for easy circuit identification.
