Overview

The BOJACK Terminal Fuse 300A MRBF is a compact, high‑amp protection device designed for both automotive and marine electrical systems. With a 58VDC rating and 300A nominal current, it delivers robust circuit protection in tight spaces, while meeting essential DC main circuit requirements for large battery banks. The fuse boasts an impressive 10,000 AIC at 14VDC and IP66 waterproofing, making it suitable for demanding environments. An ignition‑protected design per SAE J1117 adds a layer of safety for installations aboard gasoline powered craft.
