    2 pole Miniature Circuit Breaker Details

    Tips: Wiring means of circuit breaker
    The wiring means of the circuit breaker includes five types, which are respectively front-panel wiring, back-panel wiring, plug in, pull-out wiring and rail type.

    1. Front-panel wiring
      This is a most pervasive wiring means. When the circuit breaker is installed into a set of equipment together with switch cabinet, power distribution cabinet etc., the wires are connected in front of the panel and fastened by bolts, that is, the power lines and load lines are directly connected in front of the wiring panel of the circuit breaker.
    2. Back-panel wiring of the circuit breaker
      This means when the circuit breaker is installed on the package equipment, at the back of the installing plate, there are six wires on the junction plate of the circuit breaker base(three at the power terminal and three at the load terminal) which have been tightened by the nuts passing through the bolts of the installing panel and connecting with the power line and load line.
    3. Plug-in wiring
      It means to install one installation base of the circuit breaker on the installing panel of the package equipment. There are six plugs on the installation base while six sockets on the connecting panel of the circuit breaker. There is a connecting panel on the surface of the installation base (front-panel wiring of the insert type) or there are bolts at the back of the installation base (back-panel wiring of the insert type). The installation base is preset with the power line and load line. In using, the circuit breaker will be inserted into the installation base directly.
    4. Rail wiring
      Rail mounting is applicable to the small-size or miniature circuit breaker. The circuit breaker is embedded into the rail and then carries out front-panel wiring.
    Existing reviews of 3 amp 2 pole Miniature Circuit Breaker
    Seems like an excellent product.
    I like this 2 pole MCB is DIN mounted and it works excellent. Used it as a breaker off of my battery solar bank. Well-made and easy to use. Highly recommend.
