    Circuit Breaker

    What is MCB?

    Mini Circuit Breaker (MCB), also known as miniature circuit breaker, is a current-limiting, high-breakage miniature circuit breaker with overload and short-circuit double protection.With advanced structure, reliable performance, strong breaking capacity, beautiful and compact appearance, etc., the miniature circuit breaker is widely used in industrial, commercial, high-rise and civil housing and other places.

    TOMD6 is the new generation of products from Tongou,it is suitable for AC 50Hz/60Hz, rated voltage 230V, rated current 63A and below in the circuit, as line overload and short circuit protection.

    What is the difference between DC MCB and AC MCB?

    Mini Circuit Breaker (MCB), also known as miniature circuit breaker, is a current-limiting, high-breakage miniature circuit breaker with overload and short-circuit double protection.With advanced structure, reliable performance, strong breaking capacity, beautiful and compact appearance, etc., the miniature circuit breaker is widely used in industrial, commercial, high-rise and civil housing and other places.

    DC Mini Circuit Breaker:

    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.

    AC Mini Circuit Breaker:

    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.

    Usage Scenarios:

    ——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.
