About the ATC/ATO Blade Fuse

The ATC/ATO blade fuse is the industry-standard automotive fuse used in virtually all Australian vehicle fuse boxes, marine fuse panels, caravan fuse blocks, and 12V DC accessory circuits. The blade fuse format uses a colour-coded plastic body with two flat metal prongs that plug directly into a standard blade fuse holder or fuse block — making replacement fast and straightforward without tools.

The 3 Amp rating makes the 3BF suited to low-current control circuits, small lighting loads, instrument illumination, and electronic accessories where a 3A circuit protection level is specified. The violet housing immediately identifies the fuse as a 3 Amp unit, consistent with the standard ATC colour code used across all Australian automotive, marine, and 12V applications.

Q: What is the difference between ATC and ATO blade fuses?
A: ATC (closed) and ATO (open) refer to whether the top of the fuse body is enclosed or open — both are the same physical size and are interchangeable in standard blade fuse holders. The 3BF suits both ATC and ATO fuse holders.

Q: How do I know which amp rating I need?
A: Match the fuse to the circuit it protects — the fuse should be rated at or just above the normal operating current of the circuit, but below the current that would damage the wiring. Always refer to the vehicle or equipment wiring diagram for the correct fuse rating. Never replace a blown fuse with a higher rated fuse without identifying and rectifying the fault.

Q: How many fuses are in a pack?
A: The 3BF is sold in a pack of 5 fuses.
