About the FB4BF — 4 Way Blade Fuse Box

A blade fuse box provides a centralised fuse panel for multiple 12V DC circuits — one common supply connection feeds power to multiple individual fused outputs, each protected by its own blade fuse. This is the standard approach to fusing multiple accessory circuits in Australian caravan, RV, marine, and 12V DC installations — rather than running individual inline fuse holders for each circuit, a fuse box centralises all circuit protection into a single, accessible location.

The FB4BF handles up to four separate circuits — each fuse position accepts a standard ATC/ATO blade fuse, allowing each circuit to be individually rated and protected with the correct fuse for the load. Any standard ATC/ATO blade fuse from 1A through to 40A can be used in each position, making the fuse box suitable for a wide mix of circuit types and current ratings within the same installation.

Common applications include: caravan accessory circuits (lighting, water pump, USB outlets, refrigerator, entertainment), vehicle auxiliary circuits (driving lights, air compressor, UHF radio, dashcam, auxiliary battery feeds), marine accessories (navigation lights, bilge pump, electronics), and any 12V DC installation where multiple circuits need individual fuse protection from a single supply point.

Q: Do fuses come with the FB4BF?
A: No — the FB4BF is the fuse box only. ATC/ATO blade fuses are sold separately. Select the appropriate fuse rating for each circuit being protected.

Q: What fuses fit the FB4BF?
A: The FB4BF accepts standard ATC/ATO blade fuses — the same blade fuses used in standard vehicle fuse boxes. Any rating from 1A through to 40A in the standard ATC/ATO blade format is compatible.

Q: Can different fuse ratings be used in each position?
A: Yes — each of the four fuse positions is independent. Different fuse ratings can be installed in each position to match the individual current requirements of each circuit being protected.

Q: Is the FB4BF sold individually?
A: Yes — the FB4BF is sold individually.
