Bussmann AMG-150 – Frequently Asked Questions

1) Will the Bussmann AMG-150 work on a 24-volt truck or bus system?
Yes. The AMG-150 is rated 32Vdc, which covers both 12V and 24V vehicle systems. That 32Vdc ceiling is a DC-only rating, so it is not a fuse for AC panel work or for hybrid/EV high-voltage packs running above 32 volts.
2) How does the AMG-150 fuse mount - does it use a fuse block or bolt down?
It bolts down. The AMG-150 uses a bolted blade end x bolted blade end connection, so it lands on two studs (typically a battery distribution block or a bussed power stud) rather than plugging into a clip-style holder. Plan on ring terminals or a stud block at both ends, torqued to a clean, low-resistance joint.
3) Is the Bussmann AMG-150 a fast-acting or time-delay fuse?
It has time-delay characteristics. The published response is 100 hours minimum at 100% of rating, 4 hours minimum at 110%, 90 seconds minimum to 3600 seconds maximum at 150%, and 5 to 100 seconds at 200%. That built-in tolerance for overload lets it ride through the inrush of a winch, inverter, or motor start without nuisance opening.
4) What are the physical dimensions of the Bussmann AMG-150 for fitting inside a battery box?
The fuse body measures 2.693 x .66 x .354 inches and weighs .27 lb. That thin profile is what lets it sit between stacked stud terminals in a tight battery compartment, but check the stud spacing on your block against the overall 2.693 inch length before you commit.
5) Can I tell at a glance whether an AMG-150 has blown?
No. It is a non-indicating fuse, so there is no pop-up pin or LED flag to show an open element. On a fleet where fast roadside diagnosis matters, expect techs to check for voltage across the fuse with a meter instead of eyeballing it.
6) What size wire and load does a 150A AMG fuse protect?
The AMG-150 is a 150A device, so it belongs on high-current feeds - main alternator output, battery-to-distribution cable, inverter and winch supply, upfitter power runs on fleet vehicles. Size the cable to carry 150A continuously for the run length, since the fuse protects the conductor, not the load.
7) Will the AMG-150 hold up to heat and vibration under the hood?
The housing is thermoplastic with copper terminals. The copper terminations give a low-resistance bolted joint that resists heating at the stud, and the bolted-blade design is what keeps it seated under vehicle vibration, unlike a push-in blade fuse that can back out.
