The AllSpark AS-MCB20 is a compact, resettable 20-amp mini panel mount circuit breaker engineered for reliable overcurrent protection in 12V and 24V DC electrical systems. Unlike traditional blade fuses that require replacement after every fault, this thermal trip breaker resets with a simple button press — saving time and money on the road. Rated at 20A continuous DC current with a low-profile panel-mount body, it installs flush into distribution boards, fuse panels, and custom switch panels on caravans, camper trailers, and 4WD builds.

Purpose-built for the demands of Australian touring, the AS-MCB20 is the go-to protection solution for accessory circuits including compressor fridges, lighting rigs, water pumps, USB charging hubs, and winch control lines. Whether you're wiring a new dual-battery system in your 4WD, fitting out an off-road camper, or upgrading the 12V board in your RV or motorhome, this mini breaker slots neatly into tight panel spaces while delivering solid, dependable protection against short circuits and overload conditions on every adventure.
