Features. Protects - and + poles or AC90~400V protects L and N poles High quality IP65 waterproof circuit breaker box, which can block rain and dust, making your electricity safer and more reliable Arc extinguishing: DC arc extinguishing is more difficult than AC arc extinguishing. This DC miniature circuit breaker has a magnetic system to assist in interrupting the arc. It is widely used in solar panel grid-connected system, wind and solar hybrid system and other DC circuit systems to avoid damage due to excessive current caused by overload or short circuit. It can also be used for home 120V/240V circuit switching use. Specifications.
