Maxi Blade Fuses & Holders

Maxi blade fuses and holders for higher-current automotive and 12V wiring, protecting heavier circuits against overload and short circuits. This guide explains how to choose them.

Maxi blade fuses — A maxi blade fuse is the larger version of the standard blade fuse, made for the higher currents that a bigger blade fuse can carry, such as main feeds and heavier accessory circuits. Each rating is colour-coded so you can identify it at a glance. The correct rating is set by the wiring and the circuit it protects, so match the fuse to the circuit rather than fitting a higher rating to stop it blowing. Confirm the amperage you need before ordering.

Inline fuse holders — An inline holder wires a fuse into the run itself, letting you add a fused connection to an existing circuit or a heavier accessory. It suits main feeds, auxiliary circuits and add-on equipment where a fuse box position is not available. Choose a holder rated for the circuit and sized to your cable.

Choosing the pair — Order the fuse and holder together so the rating and fit match. Keep a spread of ratings to hand, as the fuse is a consumable that needs replacing when a fault blows it. If a fuse keeps blowing, the fault needs fixing rather than fitting a higher rating.
