• Tidy high-current and branch fuse layout

• MRBF block mounts straight on battery stud

• 12-way blade block runs up to 12 circuits

• Tin-plated buses support up to 100A

• Clear cover keeps fuses visible and protected

• Accepts common ATO and ATC blade fuses

Tuff Terrain’s MRBF terminal fuse block teams with the 12-way ST blade fuse block to tidy up high-current feeds and branch circuits in one neat setup. The MRBF unit bolts straight onto 3/8" battery studs, meaning less cable, less mess, and less voltage drop across your main DC runs. The insulating cap snaps over the live stud, helping protect against accidental shorts when you are working around the battery.

The ST blade fuse block takes 12 ATO or ATC blade fuses at up to 30A per circuit, which lets you split lights, pumps, fridges, and electronics into clearly labelled zones. The built-in negative bus bar keeps returns in one spot to make fault finding simpler outback to the backyard. The clear cover uses a push-button latch for quick access, while the supplied labels keep every circuit easy to recognise. Terms and conditions apply.

Q: Are any fuses included in this Tuff Terrain fuse block bundle?

A: No, the bundle does not include fuses. This lets you choose MRBF and ATO/ATC fuse ratings that match each circuit’s load and cable size. It also means you can standardise spares across your setup. Always select fuses within the 30–300A range for the MRBF block and up to 30A per circuit on the blade block.

Q: What fuse types do these blocks accept?

A: The terminal block accepts MRBF terminal fuses and the 12-way block accepts ATO or ATC fast acting blade fuses. MRBF fuses suit high-current battery feeds where you need compact protection. ATO and ATC fuses cover typical accessory circuits like lighting, fridges, and pumps. Using common formats makes replacements simple across Australia.

Q: Can the 12-way fuse block be used on 24-hour circuits?

A: Yes, the ST blade fuse block can be wired for 24-hour circuits. A direct feed from the battery or main distribution bus keeps selected circuits powered when the ignition is off. This suits alarms, trackers, fridges, or bilge pumps. Correct cable sizing and fuse values remain critical for every always-on load.

Q: What terminal types can I use with the blade fuse block?

A: The 12-way block accepts ring or snap fork type terminals. Ring terminals give strong mechanical retention on vibrating vehicles or boats. Snap fork terminals let you remove a circuit without fully undoing the screw. Always crimp terminals with the correct tool to prevent hot joints under load.

Q: What is the maximum system voltage for these fuse blocks?

A: Both the MRBF terminal block and the ST blade fuse block are rated to 48V DC maximum. This covers common 12V and 24V setups and some higher-voltage systems within the rating. Never exceed 48V DC, as higher voltage can arc across gaps and damage the blocks. Always confirm your system voltage before installation.
