Residual current action breaking time


In(A) In(A) Breaking time (s) when the residual current is equal to the following value
In 2In 5In 5A、10A、20A、50A、100A、200A It
6~40A 0.03、0.1、0.3 0.1 0.05 0.04 0.04 0.04
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
c B、C 2.55In cold state 1s trip  
d B 3In cold state t≤0.1S Does not trip  
5In t<0.1S trip
e C 5In t≤0.1S Does not trip  
10In t<0.1S trip
