    3 pole Miniature Circuit Breaker Details

    Tips: Measurements of molded case circuit breaker prevent the burning of brake windings

    1. Time delay normally open contact is changed to a pair of normally open contact. Auxiliary switch contact and auxiliary switch arm screw are often checked. The position of auxiliary switch is adjusted correctly to make sure that auxiliary switch and circuit breaker brake are put in the right position where they work efficiently.
    2. Coil of brake is well fixed and its iron core is often checked to make sure that it runs smoothly.
    3. The switch-on time generated by protection control device is capable of switching on the coil brake and quitting the switch-on order in a short time.
    4. In the annual maintenance work, the connecting rod mechanism of circuit breaker should be properly adjusted and the free tripper of circuit breaker is often checked to make sure it works well and it can be disconnected reliably in the rated low voltage between 30% and 65%.

    Easy to install.
    I bought these 3 pole miniature circuit breakers as additional protection for my solar panels. They are easy to install and work great. They function perfectly. I am pleased with my purchase.

    Great miniature circuit breaker.
    This little MCB shipped quickly and worked great on my solar system. Easy installation, even though just a 32 amp breaker, there is a lot of room for large wires in lugs. If you are building a solar system, buy it.
