    Tips: Types of the low-voltage circuit breakers
    The low-voltage circuit breaker is also named as the automatic air switch. It is mainly used as the power switch in the low-voltage distributing line or switch cabinet (box) not operated frequently and can be used to control the motor not started frequently. When there is any serious overcurrent, overload, short circuit, phase loss, electricity leakage and other faults, it can cut off the power supply automatically and play a role of protection.

    1. Air circuit breaker in frame type(conventional)-ACB
      All components of ACB are installed in one insulated metal frame. It is normally the open-type. It can be equipped with several accessories, so the exchange of contact terminal and component are rather convenient. It is mostly used for the main switch of the power terminal.
    2. Molded case circuit breaker-MCCB
      MCCB can cut off the current automatically when the current exceeds the current tripping setting. MCCB usually includes the thermomagnetic tripping unit. However, the large-size MCCB will be equipped with the solid tripping sensor. It is appropriate for being the protective switch of the branch.
    3. Miniature circuit breaker-MCB
      MCB is a kind of terminal protective equipment which is mostly extensive used in the power distribution unit of the architecture electric terminal. It is used for the single-phase, three-phase short circuit, overload and over pressure protections below 125A, including the single pole 1P, dipolar 2P, tripolar 3P and quadrupole 4P.
    Existing reviews of 63 amp 2 pole Miniature Circuit Breaker
    I am happy with this purchase.
    I got one of this 2 pole miniature circuit breaker to disconnect the solar panels from the controller and to protect the whole system. This is working well. Very easy now to turn power on and off to the charge controller. I am happy with this purchase.
