①DC Current Characteristics: DC MCBs are able to adapt to the continuous and stable characteristics of DC current without naturally crossing zero as in AC current.
②Special design: DC MCBs are usually equipped with special contact materials and interrupter chamber designs to cope with the continuous characteristics of DC arcs.
③Overload protection: DC MCBs are able to effectively prevent overloads due to overcharging of batteries or reverse currents in PV systems.
①AC CURRENT CHARACTERISTICS: AC circuit breakers are suitable for AC currents and are able to utilise the natural zero crossing point of the current to break the circuit more easily.
②Wide range of applications: AC circuit breakers are suitable for AC power distribution in most standard residential and commercial buildings, as well as in industrial environments.
③Cost Effective: AC circuit breakers are typically more economical than DC MCBs due to their wide range of applications and production scale.
④Ease of Installation: AC circuit breakers are relatively simple to install and maintain and require no special skills or equipment.
——DC Power Systems: For DC power systems, such as solar photovoltaic systems, battery storage systems, etc., DC MCBs are a more suitable choice because they are specifically designed to handle the characteristics of DC current.
——AC Power Systems: For standard AC power systems, such as power distribution in homes, offices and industrial facilities, AC circuit breakers provide an economical and effective protection solution.
