BOJACK MRBF Terminal Fuse Block 60A Marine Battery Fuse Holder IP66 Waterproof, Stainless Studs

BOJACK MRBF Terminal Fuse Block is a compact, marine-rated 60A battery fuse holder that protects high-current DC circuits up to 58V while resisting water and dust with an IP66 rating.

This dual MRBF fuse block combines robust materials and a small footprint so you can add reliable circuit protection where space is limited. Built from temperature-resistant PA66 thermoplastic and stainless-steel studs, the assembly accepts a 60A MRBF fuse and ships with a waterproof insulating cap and mounting hardware. It’s designed for boat, vehicle and industrial DC systems that demand corrosion resistance, strong conductivity and easy installation.

How does this fuse block protect my high-current DC system?

The BOJACK MRBF holder interrupts excessive current flow using a replaceable 60A MRBF fuse element, preventing wiring and component damage from sustained overloads. Its ceramic insulation and nickel-plated copper alloy fuse ensure consistent contact and thermal stability under heavy loads.

• Rated for up to 58V DC and 60A continuous current
• Ceramic insulation and thermoplastic PA66 body for heat resistance
• Nickel-plated copper alloy fuse strip for reliable conductivity
• Stainless-steel studs and nuts resist corrosion in marine environments

Is the fuse block suitable for marine and outdoor use?

Yes — the unit meets IP66 protection class, shielding the fuse from heavy spray and dust ingress. The included waterproof red cap covers the terminal to reduce accidental shorts and minimize environmental impact on electrical performance.

• IP66-rated enclosure resists water jets and dust
• Sealable insulating cap prevents accidental contact
• Stainless fasteners reduce corrosion in saltwater settings
• Compact footprint fits tight installations on boats and vehicles

What are the physical and electrical specifications I should know?

The block accepts an M8 (5/16") stud and mounts with an M10 (3/8") hole, making it compatible with common battery and busbar hardware. The fuse material and holder thicknesses are chosen for strength and low resistance to preserve voltage under load.

• Fuse rated current: 60A; maximum voltage: 58V DC
• Stud size: 5/16" (M8); mounting hole: 3/8" (M10)
• Body: PA66-RG301 thermoplastic; studs: stainless steel
• Fuse strip: 2.5mm copper alloy, nickel-plated; housing: clear PES plastic

How easy is installation and maintenance?

Installation is straightforward: secure the holder with the M10 mounting hole, attach battery leads to the M8 studs, and fit the supplied MRBF fuse. Replacement is fast — lift the waterproof cap, swap the MRBF cartridge, and reseal the cover to restore protection.

• Comes with washer, lock washer, hex nut and one 75A fuse (choose required amperage before purchase)
• Replaceable MRBF cartridge simplifies service without rewiring
• Compact layout allows mounting in cramped panels or near battery terminals
• Clear fuse housing provides visual inspection of fuse condition

Who is this for? The BOJACK MRBF Terminal Fuse Block is ideal for boat owners, RV and motorhome builders, off-grid inverter setups, light industrial equipment and custom automotive installations that need a compact, corrosion-resistant fuse solution. If you require dependable high-current protection in wet or dusty environments and prefer easy servicing, this fuse holder offers a durable, conductive and space-saving option.
