Tuff Terrain puts the MRBF terminal fuse block and 12 circuit ST blade fuse block in one tidy kit, letting you run a main feed and up to 12 branches off the same setup. The MRBF block sits on your 3/8" battery stud, handling 30–300A protection for big loads like inverters, winches, or bow thrusters. The cap covers the live terminal, meaning stray tools or lugs do not arc across the battery.

The ST blade block brings a positive and negative bus together, which keeps your wiring neat from the bush to the beach. Tin‑plated copper tracks carry up to 100A total with 30A max on each fused way, giving plenty of headroom for lights, pumps, fridges, and comms. The clear cover and circuit labels line up every fuse position, so fault‑finding on the road stays quick and simple.

Q: Are MRBF fuses and blade fuses included in this kit?

A: No, all fuses are sold separately.

This kit supplies the terminal and blade fuse blocks only, meaning you choose ratings to match each circuit. MRBF fuses cover the 30–300A range for the main feed. ATO or ATC blade fuses suit the 12 branch circuits. Always match each fuse size to the cable and load.

Q: What voltage systems can this Tuff Terrain kit be used on?

A: The kit is rated up to 48V DC.

That covers typical 12V and 24V setups found in vehicles and marine systems. The rating refers to maximum system voltage, not recommended operating voltage. Always confirm your system voltage is within this limit. Follow standard wiring and fuse selection practices.

Q: What type of terminals can I use on the 12 circuit blade fuse block?

A: The ST blade fuse block accepts ring or snap‑fork type terminals.

These terminal styles fit the screw connections on each circuit way. Ring terminals give a more captive connection on mobile setups. Snap‑forks help when you need quicker removal under a screw head. Use correctly sized lugs for the cable cross‑section and screw size.

Q: Can the MRBF terminal fuse block be stacked with other lugs on the same stud?

A: Yes, the isolated stud design permits stacking of terminals.

The block uses a standard M8 stud layout, which lines up with common battery and busbar hardware. You can place cable lugs under or over the MRBF fuse base as required. Always follow torque recommendations and keep contact faces clean.

Q: Is the MRBF terminal fuse block ignition protected?

A: The MRBF terminal fuse block is ignition protected when used with an MRBF terminal fuse.

Ignition protection means the assembly will not ignite surrounding flammable vapours under normal fault conditions. This feature suits many marine and engine bay installations. Always check applicable standards for your vessel or vehicle before installation.
