Bussmann 184150F-03-1 – Frequently Asked Questions

1) Can the Bussmann 1841 series 150A breaker be used on a 24V or 12V vehicle system?
Yes. The 184150F-03-1 is rated 42 Vdc, so it covers 12V and 24V DC vehicle and equipment systems up to that ceiling. Its interrupting rating is 3 kAIC at 30 Vdc. It is a DC-rated automotive breaker, so don't put it on an AC circuit.
2) What cable lugs and hardware do I need to land wire on the Bussmann 184150F-03-1?
The terminals are 1/4 inch - 28 TPI studs, so you need ring lugs with a 1/4 inch hole sized for your cable. Stainless steel nuts and washers come with the breaker. Torque the stud nuts to 50 lb-in.
3) Is this Bussmann 150A breaker a manual reset, or does it reset itself?
It's a manual, switchable unit. The 1841 series breaker uses a reset lever actuator, so after a thermal trip someone has to flip it back by hand, and the same lever lets you switch the circuit off deliberately for service. If you need a breaker that re-closes on its own after cooling, this isn't it.
4) Can I use the Bussmann 184150F-03-1 as a battery disconnect switch?
It doubles as one on a single circuit. The reset lever is switchable, so you can open the circuit manually for maintenance, and it's single-pole, meaning it protects and breaks one conductor only. It is not a two-pole or main isolator for both battery legs.
5) Will this 150A Bussmann breaker hold up mounted in an engine bay?
Operating temperature runs -25 to 180 degrees F, which covers under-hood and enclosure heat in most vehicle and off-road equipment installs. Keep in mind it's a thermal breaker, so sustained high ambient temperature brings the trip point down relative to a cool location.
6) Should I use a 150A breaker like this or a fuse and holder on a DC feed?
A resettable breaker makes sense where the circuit trips occasionally and you want it back on without carrying spares, such as inverters, winches, and auxiliary power feeds. It also gives you a switch to kill the circuit for service, which a fuse doesn't. A fuse block is the better pick when you want the smallest possible footprint and no moving parts. This 1841 series unit is thermal and switchable with a reset lever.
7) What amperage and part number do I order to match an existing Bussmann 1841 breaker?
The exact part is Bussmann 184150F-03-1, an Eaton 1841 series single-pole breaker rated 150 A. If the unit you're replacing is a different amperage, the 1841 series number changes with it, so read the rating off the old body before ordering.
8) Does the Bussmann 184150F-03-1 carry any compliance marking?
It's CE marked. That's the rating stated for the 150A 1841 series breaker; no other listing mark is carried on the part record.
