About this product

Marine Rated Battery Fuse (MRBF) for direct-on-terminal high-interrupt DC circuit protection.

Protects lithium leisure battery and AGM battery banks against sudden high fault currents by interrupting short circuits directly at the terminal post. This Marine Rated Battery Fuse (MRBF) mounts straight onto M8/M10 studs, providing high-interrupt capacity right where your cables connect to protect your wiring from fire hazards. Direct post mounting eliminates unfused cable runs between the battery and main distribution points. If you require compact, ultra-reliable circuit protection for high-discharge batteries, choose between 100A and 300A ratings.
