    1 pole Miniature Circuit Breaker Details

    Tips: Working principle of 1 pole miniature circuit breaker

    The miniature circuit breaker is composed of operating mechanism, contacts, protection devices, arc extinguishing system, etc. The main contact is manually operated or electrically closed. After the main contact is closed, the free trip mechanism locks the main contact in the closing position. The coil of the overcurrent release and the thermal element of the thermal release are connected in series with the main circuit, and the coil of the undervoltage release is connected in parallel with the power supply. When the circuit is short-circuited or severely overloaded, the armature of the overcurrent release pulls in, causing the free tripping mechanism to operate, and the main contact disconnects the main circuit. When the circuit is overloaded, the heating element of the thermal trip unit will bend the bimetal and push the free trip mechanism to move. When the circuit is under-voltage, the armature of the under-voltage release is released. It also makes the free trip mechanism act.

    Easy to install
    This was purchased as additional protection and as a quick disconnect for my solar panels. I have a combiner box with breakers and lightning arrestor, but wanted the additional safety/security.
