150A AGC High-Current Fuse for Marine DC Systems
Heavy-duty overcurrent protection for high-current marine DC circuits. This 150-amp AGC fuse is designed for main feed and high-draw circuit protection applications where a standard blade or glass tube fuse isn't rated for the load. Fast-blow design trips quickly under overload to protect wiring and connected components before damage occurs.
At 150A, this fuse is purpose-built for protecting large DC loads and main battery feed circuits rather than individual accessory circuits.

Parts Desk Insights
The 150A AGC is a high-current fuse in a format that bridges the gap between standard panel fuses and full ANL fuses. It's the right choice when your circuit demands more than a standard blade fuse can handle but your existing holder is AGC-format. For main battery cable protection at similar or higher amperage using an ANL format, the 300A ANL Fuse Block with Cover – BSS-5005 is worth considering for new builds. For the AGC inline fuse holder to complete this install, see the Inline AGC/MDL Fuse Holder – BSS-5063. For lower amperage AGC fuses, the family ranges from 0.25A (BSS-5201) through 25A (BSS-5219). Always size your fuse to the wire gauge, not just the load.
