c.Short time delay over-current protection characteristic
d.Short time delay over-current protection is with fixed time setting. When inverse time limit is required to be low multiples, its characteristic
should according to I2Ts=(8Ir1) 2 ts, ts is for common delay time setting; when pver load current >8 Ir1 , automatically changes to fixed
time setting characteristic, its characteristic view table below, time accuracy is ±15%.
