    Tips: What are A, B, C and D tripping curves of the circuit breaker?
    As to the miniature circuit breaker, there are a total of four kinds of magnetic tripping curve types. The tripping curve can be A/B/C/D:

    1. A-model tripping curve
      The magnetic tripping current is (2-3)In. It is suitable to protect the semiconductor electronic circuit, measurement system with small-power power transformer or system with long circuit and low current.
    2. B-model tripping curve
      The magnetic tripping current is (3-5)In. It is suitable to protect the power distribution system of the residents, household appliances and personal safety.
    3. C-model tripping curve
      The magnetic tripping current is (5-10)In. It is suitable to protect the distributing line and the lighting line with a relatively high connecting circuit.
    4. D-model tripping curve
      The magnetic tripping current is (10-20)In. It is suitable to protect the equipment with a relatively high impulse current, such as the transformer and solenoid valve and so on.
