Residual current action breaking time
|In（A）||I△n（A）||Breaking time (s) when the residual current is equal to the following value|
|Note: a. 5A, 10A, 20A, 50A, 100A, 200A tests are not tested for current values that are greater than the lower limit of the current instantaneous tripping range; b. Overcurrent instantaneous tripping when I△t is equal to Type B and Type C The test is carried out at the current at the lower limit of the range.。|
Overcurrent protection tripping characteristics (reference temperature 30℃)
|test||Type||Test current||starting state||Trip or not trip time limit||expected outcome||Remark|
|a||B、C||1.13In||cold state||t≤1h||Does not trip|
|b||B、C||1.45In||Immediately after a test||t<1h||trip||The current rises steadily within 5s|
