    Tips: Different types of break curves of miniature circuit breaker

    • A trip curve: The magnetic tripping current is (2-3) In, which is suitable for protecting semiconductor electronic circuits, measuring circuits with low-power transformers, or systems with long circuits and low currents.
    • B trip curve: The magnetic tripping current is (3-5) In, which is suitable for pure resistive loads and low-voltage lighting circuits. It is often used to protect household power distribution systems, household appliances, and personal safety.
    • C trip curve: The magnetic tripping current is (5-10) In, which is suitable for inductive loads and high-inductance lighting circuits, and is often used to protect power distribution lines and lighting lines with higher on-current.
    • D trip curve: The magnetic tripping current is (10-20) In, which is suitable for systems with high inductive loads and large inrush currents, and is often used to protect equipment with high inrush currents, such as transformers, solenoid valves, etc.
    Existing reviews of 16 amp 2 pole Miniature Circuit Breaker
    High quality MCB
    I use this 16A 2 pole miniature circuit breaker as a switch on the DC input side of the PV charge controller. The DIN rules are wide enough and its functions are perfectly, with a nice positive feel at startup. It is a very good and high quality MCB that deserve 5 stars.
