XS Power FU-350 350 Amp ANL Fuse – Silver Finish

The XS Power FU-350 is a 350 amp ANL fuse with a silver finish, made for the main power run in a serious car audio install. It drops into any standard ANL fuse holder and sits in line between the battery and the amplifier, so if the power wire ever shorts against the chassis, the fuse blows instead of the wire burning. XS Power is the battery brand behind a lot of big audio builds, and this is the fuse they make to match their hardware.

A main fuse this size protects the wire, not the amplifier — the amp has its own fuses on board. Size the fuse to what the wire can carry: 350 amps is 1/0 AWG territory, the heavy copper feeding one large amplifier or a distribution block serving several. Go too small and you'll pop fuses on hard bass hits. Go too big and the wire becomes the fuse, which is exactly what you're trying to avoid.

Fits Standard ANL Fuse Holders

The FU-350 is a wafer-style bolt-down fuse. Two slotted lugs clamp under the holder's bolts, so vibration can't work the connection loose the way it can with a spring-clip fuse — a real consideration on a daily driver taking Northeast Ohio roads all winter. It interchanges with any standard 350 amp ANL fuse, including Bussmann's ANL-350, so if that's what's blown in your holder, this replaces it. One honest caution: if your holder takes Mini-ANL (AFS) or MIDI fuses, this one is physically larger and will not fit. Check your holder before you buy, or call us and we'll check it with you.

Key Features

• 350 amp rating covers 1/0 AWG power runs and multi-amplifier systems
• Standard ANL wafer size fits XS Power and other common ANL fuse holders
• Silver finish on the contact lugs for clean, low-resistance connections
• Bolt-down lugs hold tight where spring-clip fuses can rattle loose
• Direct interchange for other 350A ANL fuses, including Bussmann ANL-350

The same fuse does duty outside car audio: high-current marine DC runs, dual-battery setups, and inverter feeds all use ANL fuses in this range. If you're not sure a 350 amp fuse is the right size for your wire and load, tell us the gauge and what it's feeding — we'd rather check twice than sell you the wrong one.
