Blue Sea Terminal MRBF Fuse Block 2 Stud (2151)

Designed for high-performance DC systems, the Blue Sea 2-Stud MRBF Terminal Fuse Block is ideal for installations where compact, high-current protection is essential. With its dual-stud layout, it facilitates direct connection of two fuses - perfect for systems with parallel circuits or dual loads such as battery banks, inverters, or bow thrusters.

Constructed to fit in tight spaces, the block supports up to 300A and 58V DC, ensuring reliable protection for even the most demanding applications. The isolated M8 (5/16") terminal studs allow for secure stacking of ring terminals and simple installation using standard hardware.

For added safety, the fuse block includes an insulating cap to prevent accidental short circuits. While not ignition protected on its own, it becomes ignition protected when paired with Blue Sea Systems' MRBF Terminal Fuses, making it safe for use near engines or batteries.

The fuses are sold separately, allowing you to choose the appropriate amperage (60A-300A) to suit your specific setup.
