About This Product
When you're working with high-current electrical systems – like in vehicles, boats, or industrial equipment – you need a fuse that's up to the job.
This ANM MEGA bolt-down fuse is built for serious amp loads.
This one is rated at 400 amps, but the series ranges from 40A all the way up to 500A, so there's a version for just about any heavy-duty application.
It's a time-delay fuse, which means it can handle brief spikes in current without blowing instantly – useful for systems with motors or other inductive loads that draw a big surge on startup.
Once that surge passes, the fuse holds steady under normal load.
But if current keeps climbing, it'll blow and protect your equipment.
Voltage ratings are flexible too – it works with 32V, 48V, 72V, and even 125V systems.
The physical size is MEGA type – about 68 x 16mm – with bolt-down terminals for a secure connection that won't vibrate loose.
The materials are Bakelite housing with copper terminals – that gives you a rugged, heat-resistant fuse that handles high heat without degrading.
It's a reliable failsafe for alternators, battery banks, inverters, and other high-power gear.
If you need a serious fuse for a serious electrical system, this is it.
