    Tips: Circuit breaker working principle
    The main contacts of low voltage circuit breaker are operated manually or electrically. After the main contact is closed, it will be locked by the free tripping mechanism. The trip coil of over-current and the thermal element of thermal overload releaser are connected in series with the main circuit. The under-voltage releaser coil and the power supply are connected in parallel.

    1. When the circuit is short-circuited or severely over-loaded, the armature of over-current releaser will be pulled in to make the main contact cut off the main circuit under the effect of the free tripping mechanism.
    2. When the circuit is overloaded, the thermal elements of thermal releaser will bend the bimetal plates by heating to cut off the main circuit under the effect of the free tripping mechanism.
    3. When the circuit is in the state of under-voltage, the armature of under-voltage releaser will be released to cut off the main circuit under the effect of the free tripping mechanism.
    4. When the shunt trip is pressed, its armature will be pulled to cut off the main circuit under the effect of the free tripping mechanism.

    Fit perfectly, works like it should.
    This 1-pole miniature circuit breaker fit perfectly in my 125 amp OQ panel. I used it for an RV hookup, works great and will trip when needed.
