3, C tripping curve: magnetic tripping current for (5-10), In suitable for distribution line protection and lighting circuit with high current is switched on, the feature is the most commonly used, is commonly used In building lighting electricity, etc.

4, D type tripping curve: magnetic tripping current for (10-20) In, is suitable for protection has very high impact current devices, such as transformer, solenoid valve, etc., 10 to 20 times the rated current, commonly used In power distribution.
