200A DC Circuit Breaker for 12-48V Systems

This waterproof circuit breaker provides high-current overload protection for automotive, RV and marine electrical systems. It operates across 12, 24 and 48 volt DC circuits with a 200 ampere rating. The unit mounts on a panel or firewall and accepts 0, 2, 4 and 8 gauge power cables with the supplied adapter.

Push-Button Reset and Kill Switch Function

The manual reset button doubles as a main disconnect and kill switch, letting you isolate the circuit without replacing a fuse. A protective rubber bolt cover shields the terminals, while the high-temperature plastic and zinc-alloy steel housing resists heat and moisture. Built-in terminal blocks simplify wiring for both battery input and auxiliary output.

Suited for High-Current DC Installations Needing

Installers who want a reusable alternative to blade fuses on amplifier, winch or accessory feeds will benefit from the reset function and 200A capacity. Builders requiring AC voltage ratings, lower amperage limits or automatic reset behaviour should look at other devices.

Questions about this item

Does the 200 A breaker ever need its internal fuse element replaced after a trip?

No. The unit uses a manual push-button reset instead of a replaceable fuse link, so nothing is consumed during an overload event.

What stops the breaker from carrying 200 A continuously in a hot engine bay?

The plastic and zinc-alloy housing is rated for high temperature, but sustained 200 A load will eventually trip the thermal mechanism as its primary limit.

How much heat or noise does the 200 A breaker produce when it stays closed all day?

The device is passive with no fan or moving parts, so it generates no audible noise and only the normal warmth of a 200 A current path.
