30A fuses

A 30A fuse protects a relay-fed work light bank, a winch feed or a main accessory circuit on a tractor or trailer. This page lists every 30 amp fuse in the range: standard blade (ATO) fuses, mini and micro blade fuses for modern cabs, maxi fuses for heavier feeds and glass fuses for older machines and accessories, singly and in trade packs, plus inline holders that take them.

Choosing a 30A fuse

Replace a blown fuse with the same type and rating; the product page states the fuse format so it matches the holder. When adding a circuit, a 30A fuse suits a load up to 24A continuous, and the fuse sits within 300mm of the battery on the new feed. Blade fuses are colour coded to their rating, so a 30A fuse is always the same colour whatever the brand. Other ratings are on the fuses and fuse holders page, and the relays and switches on the same circuit are under relays and switches.
