Tripping scope as per smooth DC residual current (type B shall meet following requirements on the premise of type A)

For sinusoidal AC residual current no more than 1000Hz, the trip current range between diferent frequencies according to the requirements of Table 2.With a sudden residual trip current in Table 2, the breaking time should be no more than 0.3s,The minimum no trip time of type S should be no less than 0.13s, and the maximum breaking time should not exceed 0.5s.
lf smooth residual current 0.4 time rated residual operation current (I△n) or 10 mA smooth DC residual current (the bigger shall prevail) is overlapoed on the rated frequency AC residual current. type B RCCB shall be operated. and the AC trippind current shall be no more than l△n.
If smooth DC residua current 0.4 tme rated residual operation current (I△n) or 10 mA smooth DC residua current (the biocer shaprevai) is overlapped on the pulse DC residual current. type B RCCB shall be operated. The tripping current of RCCB with l△n > 0.01A shall be no more than 1.4 l△n while the tripping current of RCCB with l△n≤0.01 A shall be no more than 2l△n.
For the pulse DC residual current which is stably increased and produced by two relative rectifying circuits, type B RCCB shall be actuated within the scope of 0.5 l△n to 22 1△n Type B shall trip within the time range specified according to the Table 1,With a sudden pulsating DC residual current applied to the rectifier circuit.
For the pulse DC residual current which is stably increased and produced by three relative rectifying circuits, type B RCCB shall be operated within the scope of 0.5 l△n to 22 1△n Type B shall trip within the time range specifed according to the Table 1,With a sudden pulsating DC residual current applied to the rectifier circuit.
For the smooth DC residual current which is stably increased, type B RCCB shall be operated within the scope of 0.5 l△n to 22 1△n Type B shall trip within the time range specifed according to the Table 1.With a smooth DC residual current applied to the rectifier circuit.
According to the Table 3, composit wave and initial value provided in steady.RCCB composite wave residual current range of 0.5I△n to 1.4 1△n, Sudden application of 71△n,Normally the RCCB break time should be less than 0.04s, Type S RCCB break time should be less than 0.15s.
